In October we’ve been collecting native plant seed in our parks. After all the work of growing, flowering, and making seed, plants have one more task for the year: dispersing the seed. Fluffy seeds ride the wind, buoyant seeds float on water, tasty seeds ride in the guts of animals, and “sticker” seeds cling to animal fur (or your favorite pair of socks!). And a few seeds ride in the paper bags of industrious humans! So it’s all hands on deck to collect seed during harvest time!
We collect native seeds to continue our natural areas restoration work throughout the parks. In 2019 we spread quite a bit of seed at Charles Ilsley Park, Stony Creek Ravine Nature Park, and Bear Creek Nature Park in areas where we had removed invasive shrubs. The competition from native plants helps prevent non-native species from coming back. We also spread native plant seed after controlled burns to help increase plant diversity in an area.
We try to remove only about one-third of the available seed for any of our target species. We want to leave enough seed to maintain healthy populations of native plants, while also providing food for birds and other wildlife. If the area is large enough we collect from many different plants to ensure that our seed has lots of genetic diversity.
We collect seed on a small scale, so we mostly harvest by hand. For some plants we simply snip the dried inflorescence from the plant, collecting the entire seed head. This method works best for species that are very tough and difficult to remove by hand (Black-eyed Susan), and for plants with seed that might shake off easily (asters). We also strip seed from the stem by hand. We use this method for many grasses when the seeds are mature and easy to remove from the stem. We place the collected seed in paper bags so that it can dry without molding or rotting.
After the seed dries we clean it so that it is easier to mix and spread. We remove the seeds from the seed heads, pods, or other “fruits,” and winnow out any excess plant material. We only need the seed clean enough to combine with other species in seed mixes. We aren’t too worried about some extra leaves, stems, and other chaff. Our end product is a nice bag of seed packaged in plastic bag to keep extra moisture out.
We are almost finished collecting seed for the season since most of the plants have dispersed their seeds. Keep an eye out for next year’s fall newsletter to see which days we will be collecting seed in 2020. If you are interested in helping us this year, we have a seed cleaning work day on December 3, 2019 from 12:30 – 3:30 pm at Watershed Ridge Park (1720 W. Buell Rd). If you have any questions about this work day or any questions about seed collecting don’t hesitate to ask!
Wow! 2018 was another big year for the Natural Areas Stewardship program. We completed botanical inventories of several small parcels. The Land Preservation Millage was renewed for another 10-year term. Major invasive shrub control projects began at Bear Creek Nature Park, Blue Heron Environmental Area, Charles Ilsley Park, Paint Creek Heritage Area – Wet Prairie, and Stony Creek Ravine Nature Park. Volunteers monitored vernal pools, lakes, and nest boxes. Our fire crew gained experience and was able to complete several burns in the spring. Our planted prairies from 2015 really started to look like prairies in 2018. And the word continued to spread about our natural areas stewardship program and the wonderful, consistent support from our township residents. What fun! Check out the highlights of the year below, or read the full 2018 Annual Stewardship Report. (Click link to view). The table of contents in the PDF is hyperlinked to help you navigate the report.
Volunteers contributed 1212 hours in 2018! Weekly bird walks continued, gathering useful data about avian life in the park and engaging residents. Volunteer workdays focused on garlic mustard (May), invasive shrub control (July to November), and seed collecting (October). Volunteers also monitored nest boxes at Draper Twin Lake Park, Charles Ilsley Park, and the Paint Creek Trail; monitored vernal pools at Bear Creek Nature Park; and monitored water quality at Lost Lake and Twin Lake. We had fun at summer and winter potlucks and the December birder coffee hour!
The nest box monitoring program was made possible by volunteer Tom Korb, who built, helped install, and Charles Ilsley Park, Draper Twin Lake Park, and the Paint Creek Trail. We enjoyed watching bluebirds and tree swallows nesting in these new boxes!
Prairie Restoration with USFWS Partners for Fish and Wildlife Grants
After planting 55 acres of prairie reconstructions in 2015 and 2016, we completed our third round of plantings in 2018. Using our second Partners grant, we planted an additional 15 acres at Charles Ilsley Park and 3 acres at Gallagher Creek Park in May 2018. We continued maintenance of areas planted in 2015 and 2016, working to give native plants the upper hand during the critical establishment phase.
We contracted with Plantwise LLC for spring burns at Cranberry Lake Park(40.4 ac), Lost Lake Nature Park (24.6 ac), and Paint Creek Heritage Area—Wet Prairie (9 ac). We also worked with private landowners to burn 13.1 acres of habitat adjacent to the Paint Creek Trail right-of-way, including high quality oak savanna, prairie remnants, and fen wetland. We held volunteer prescribed burn crew training again in February. The volunteer crew completed burns at Bear Creek Nature Park (23 ac), Charles Ilsley Park (1 ac), Draper Twin Lake Park (9.4 ac), Watershed Ridge Park (2.4 ac), and Paint Creek Trail at Gunn Road (0.4 ac).
The stewardship blog continued to thrive, with regular posts from Cam Mannino. She regularly highlighted cool features across all of our parks, all with excellent writing and photographs. The blog also continued to serve as an up-to-date source of information about stewardship volunteer opportunities and events. We published 45 posts and had 6233 visitors, with 11,744 page views.
Stewardship talks included presentations on native bees, rain gardens, prescribed fire, emerging invasive species, bird nest box monitoring, and oak wilt. We enjoyed a pleasant April evening at our annual Woodcock Watch at Cranberry Lake Park.
Phragmites Outreach Program
We continued the Phragmites Outreach Program to help township residents get Phragmites treated on their property. We received about 32 requests for no-obligation cost estimates, and treated about 25 properties with a contractor, PLM Lake and Land Management.
Billy Gibala returned to our crew through June. He graduated from University of Michigan-Flint in 2017 with a degree in wildlife biology and minors in regional and urban planning, We welcomed Alyssa Radzwion to the crew. She graduated from Oakland University in December 2016 with a Bachelor’s degree in biology, and had previous experience working for the Michigan DNR stewardship crew. Katlyn Hilmer recently graduated from State University of New York College of Environmental Science and Forestry, where she focused on forestry work. Sarah Rosche joined the crew in July after completing her Master’s, studying the effects of fire on Northern Bobwhite nesting ecology and habitat selection. We had a great crew with diverse experiences!

Early summer is blooming and buzzing at Draper Twin Lake Park. The golden petals of Sand Coreopsis (Coreopsis lanceolata) ruffle in the wind among dancing white Ox-eye Daisies (Leucanthemum vulgare) and Yarrow (Achillea millefolium). What a sight for a summer afternoon!
Birds suddenly burst from the deep grass or sway on a sturdy plant stem while being tossed by the wind. Butterflies settle in sunny spots along the moist trails near the marsh or dance along a sunny prairie trail seemingly unable to choose which early summer bloom might please them. Such summery abundance after a cold spring!
Butterflies Take to the Air!
I often begin blogs with birds, because they’re the favorite wildlife for many park visitors. But for better and worse, early summer begins the high season for insects! Yes, some sting, or bite – but mostly they’re just colorful and simply amazing. On a breezy visit to the eastern side of the park, I was greeted by two Eastern Tiger Swallowtails (Papilio glaucus) dancing their courtship ritual high in the air, full of chases, flutters, soaring and falling. I craned my camera upward, clicked a few times and got lucky. An exciting first for me to get photos of butterflies in flight! (Click on photos to enlarge; hover cursor for captions.)
The male took a brief rest to sip some nectar as the female flew away. But the wind was so strong that he only paused for a few brief moments before he was blown off his flower!
Undeterred, he fed on a bit more nectar and was soon back in the sky, dancing off above the treetops with his female companion.
Nearby, a flash of orange and black made me think I was seeing a Monarch Butterfly (Danaus plexippus) among the greenery. But no! The bars at the bottom of its hindwings were the unmistakable insignia of a Viceroy Butterfly (Limenitis archippus).
Viceroys are “Müellerian” mimics, meaning they mimic the color and pattern of Monarchs which, like them, are distasteful to predators. By mimicking each other’s appearance, they give potential attackers a warning. “If you see something that looks like us, stay away or you’ll be sorry!” Isn’t evolution amazing?
In the western portion of the park, a Red-spotted Purple butterfly (Limenitis arthemis), paused on the trail in front of me. In my photo on the left, its red spots can just barely be seen on the underside of the forewing. This beautiful – and very active! – creature is said to be a “Batesian” mimic of the Pipevine Swallowtail (Battus philenor) (on the right) which is toxic to its predators. The Red-spotted Purple isn’t but its similar appearance might make an attacker think so. (Pipevine Swallowtail photo by Annabelle Corboy, an inaturalist.org photographer.)

In the grass along an eastern path sat one of the smaller butterflies much loved by generations who raised them in their classrooms or released them for special events, our very own American Painted Lady (Vanessavirginiensis). The two large eye-spots on the underside (ventral) of its hindwing distinguishes it from the Painted Lady (Vanessa cardui) which has four smaller eyespots in the same place and is widespread, appearing on every continent except Antarctica and South America.
The tiny butterflies and moths can’t claim the same glamour as the large ones, but they add their own beauty and sprightly flutter as they accompany me along the paths. (Click pause button for identification captions.)
Dragons and Damsels Flying Hither and Yon
Summer truly begins for me when damselflies settle delicately on shady leaves and dragonflies patrol prairies or ponds in search of a mate. The Common Whitetail Dragonflies are out in force right now near Twin Lake and the wetlands.
The female Eastern Pondhawk (Erythemis simplicicollis) below was hunting away from the water. She waits on vegetation until prey comes sailing by. After about two weeks, she will approach water to find a mate and choose an area of the pond in which to lay her eggs. Within one minute of mating, she will start dipping her abdomen into the water to release eggs, while the male hovers nearby.
Damselflies (in the order Odonata like dragonflies) look like delicate flying sticks. Many are iridescent or sport elaborate patterns on their abdomen and/or thorax. They are ancient creatures dating back to the early Permian, at least 250,000 years ago, and live on every continent but Antarctica.
As part of the courtship ritual, the male Ebony Jewelwing (Calopteryxmaculata) damselfly bobs up, down and around with other males in what are called “flights of attrition,” until his opponents become exhausted and leave – or he does!
I’d forgotten that the brown and black damselfly below left was a female Violet Dancer (Argia fumipennis violacea) until I got assistance at the Odonata of the Eastern U.S. Facebook page. The male is a much more glamorous purple and blue. I saw the female this week at Draper Twin Lake Park and the male there three years ago.
A Native Bird Returns to the Prairie and Avian Parenting Proceeds Around the Park
The restoration of the Draper Prairie is beginning to entice some native birds to return, as well as native plants. On a windy day, I spotted my first Savannah Sparrow (Passerculus sandwichensis) swaying on a plant stem in a stiff wind. In fact, the wind knocked him from his perch at one point, like the Viceroy butterfly mentioned above. This small sparrow with yellow over its eye may be seen more often now that restored prairies are providing the native plants that attract the insects it prefers. I couldn’t record its call in the wind, but listen here for its song that has an insect-like buzz in the middle!
I began my Draper Twin Lake Park visits with a second scolding from a male bird, akin to my escapade with the goose at Lost Lake. I approached the marsh on the eastern side of Draper Park to look at what appeared to be some female Red-winged Blackbirds (Agelaius phoeniceus) among the giant leaves of Fragrant Water Lily. Almost immediately a male blackbird began its alarm call, left its perch in the distance and flew directly toward me.
He landed in a tree next to me and never stopped expressing his irritation until I moved away. Click below to hear a worried blackbird dad!
As soon as I focused my camera’s long lens, I knew why he was upset. Fledgling blackbirds look very much like their mothers. It was clear the birds among the lily pads were his fledglings and he wanted me to back off. And I did, of course!
Another avian dad was a little further along in parenting his offspring. A male House Finch (Haemorhousmexicanus) rested on a vine near the eastern parking area and just below sat one of his offspring on a guy wire, looking straight up at Dad longingly, begging to be fed. Evidently the male thought this was no longer necessary, because no feeding was forthcoming.
As I strolled through the prairie, I watched a Tree Swallow (Tachycineta bicolor)flying open-mouthed to scoop up food for the young in its nest box. Later I saw some gnats dancing busily above the prairie grass and wondered if the large clouds of them over the prairie were part of the Tree Swallow’s diet.
A female House Wren (Troglodytes aedon) seemed to be carefully watching an Eastern Kingbird (Tyrannus tyrannus) flying near what appeared to be her nest box. The Eastern Kingbird can be fiercely territorial about its nest and later I saw it land nearby and look toward the wren’s box. But eventually it flew away. Drama avoided.
Each time I came to Draper I heard the call of the Eastern Towhee (Pipilo erythrophthalmus) – but it never appeared. It was always in dense shrubs and trees near the soggy edge of the marsh where I couldn’t approach. So here’s a 2016 photo of one throwing his head back and letting loose with “Drink your teeeeeea!”
I did, however, record the male’s wonderful song again this year. [He repeats it at 6-7 second intervals about 4 times on this recording.]
Wildflowers Provide the Colorful Backdrop for All This Activity
The restoration plantings of Draper Twin Lake Park’s northern prairie grow more luxuriant and varied every year. This summer many native wildflowers began to bloom after spending years spent sinking deep roots to resist drought. I’ll be excited to see what arrives with mid-summer and fall as natives find their footing in this gently rolling prairie. (Click pause button if you need more time for captions.)
In moister regions of the park, other native plants emerge. Scouring Rush (Equisetum arvense), a native fern-ally, produces spores on its cone that look like Indian beadwork. Fragrant Waterlilies (Nymphaea odorata) send up bright yellow club-like buds from the marsh and Wild Columbine(Aquilegiacanadensis) dangles its exotic blossoms in the shade.
Sunlight, Rain and Earth Make It All Possible
Plants deserve a bit more respect from the creatures, like us, that depend on them. We tend to notice most the animals, birds, insects that have faces like ours, I guess. But of course, all around us plants are doing the amazing work of pulling up minerals and water from the earth, soaking up sunlight from the sky and miraculously turning those elements into the food that fuels all living beings. Directly or indirectly, everything that all of us eat is provided by plants. I feel very lucky that volunteering for Dr. Ben VanderWeide, our natural areas stewardship manager, has taught me to honor a wider scope of nature. Now while I’m fascinated with wildlife, I’m also learning to notice and name the plants, particularly the native wildflowers and grasses, that have performed the miracle of photosynthesis right here for thousands of years. Such a generous gift!

After three years of consistent stewardship work in key project areas, we are beginning to see good results. New wildflower species were found at the Wet Prairie along the Paint Creek Trail. Invasive shrubs were cleared from over 20 acres at Watershed Ridge Park and Stony Creek Ravine Nature Park. Prairie species planted a few years ago at Draper Twin Lake Park and Charles Ilsley Park began to flower. And more people like you got involved in the adventure through bird walks, volunteer workdays, nest boxes, potlucks, and stewardship talks. What fun! Check out the highlights of the year below, or read the full 2017 Annual Stewardship Report (click link to view).
Volunteers contributed 637 hours in 2017! Weekly bird walks were well attended. For the first time we hosted a summer stewardship potluck to help build our conservation community. Volunteer workdays focused on garlic mustard (May), invasive shrub control (July to November), and seed collecting (October). Volunteers also helped with maintenance of native plant gardens, prescribed fire, vernal pool monitoring, and building nest boxes.
Volunteer Tom Korb led the effort to revitalize nest boxes in our parks. Tom built nearly 30 nest boxes for installation at Charles Ilsley Park and Draper Twin Lake Park. We hope to see more breeding bluebirds, kestrels, and other cavity-nesting birds in our parks in the future!
Prairie Restoration with USFWS Partners for Fish and Wildlife Grants
Using our second Partners grant we prepared sites for planting 15 acres of native prairie plants at Charles Ilsley Park and 3 acres at Gallagher Creek Park. Planting was delayed until spring 2018 due to seed shortages, but that will give us a little more time to get the site in good shape. We continued maintenance of areas planted in 2015 and 2016, working to give native plants the upper hand during the critical establishment phase.
We contracted with Plantwise LLC for spring burns at Cranberry Lake Park, Lost Lake Nature Park, and Marsh View Park. We also worked with private landowners to burn habitat adjacent to the Paint Creek Trail right-of-way, including high quality oak savanna, prairie remnants, and fen wetland. We held volunteer prescribed burn crew training again in February. The volunteer crew completed burns at Marsh View Park, Paint Creek Heritage Area—Wet Prairie, and the Art Project prairie north of Gallagher Road along the Paint Creek Trail.
The stewardship blog continued to thrive with regular posts from Cam Mannino. The blog also continued to serve as an up-to-date source of information about stewardship volunteer opportunities and events. We published 52 posts and had 5324 visitors, with 8797 page views. Natural Areas Notebook, oaklandnaturalareas.com
Stewardship hosted education events in early 2017. Topics included the importance of protecting public land in Michigan, reptiles and amphibians of Michigan, and prescribed fire in Oakland Township parks.
Phragmites Outreach Program
We continued the Phragmites Outreach Program to help township residents get Phragmites treated on their property. We received about 33 requests for no-obligation cost estimates, and treated about 21 properties with a contractor, PLM Lake and Land Management.
We had one technician return for 2017, Zach Peklo. Zach came to us from Grand Valley State University studying natural resources management with an emphasis on Geographic Information Systems. New to our crew as seasonal land stewardship technicians in 2017 were Josh Auyer and Billy Gibala. Josh graduated from Calvin College in May 2017 with a degree in Biology. Billy graduated from University of Michigan – Flint in spring 2017 with a degree in wildlife biology and a minor in regional and urban planning. Alex Kriebel also returned to our crew as a Stewardship Specialist, bringing additional experience in natural areas management from his work with Oakland County Parks and Recreation.

Charles Ilsley Park sways with grass and colorful wildflowers right now as restoration begins returning the rolling fields to the prairies they once were. The eastern prairie, featured this week, is breath-taking! Butterflies dance in and out of native Black-eyed Susans, bees hum, grasshoppers leap at your feet and dragonflies swoop above the Yarrow and Bee Balm. Birds perch and forage at the trail edges and sing from the woods.
These former farm fields, once full of invasive and non-native agricultural plants, are gradually being restored to provide for the birds, insects and other wildlife that historically nested and foraged here. A new path through the thirteen acres of the eastern prairie now provides a perfect quiet stroll on a sunny morning or afternoon.
Birds are Plentiful, Colorful and Sometimes Difficult to See
At this time of year, adult birds are busy feeding and over-seeing either nestlings or fledglings. So they’re deep in the leaves, high in the sky, or down in the grass, foraging for whatever will feed the young. Here’s a graceful female Baltimore Oriole (Icterus galbula) with seeds in her beak approaching her nearby nest hidden in a clump of leaves that hangs right over the trail as you enter the park.
Earlier in the summer, the bird boxes along the trail into the park were busy places! A House Wren (Troglodytes aedon) took over a rather dilapidated one. You’ll notice in one of these pictures, the wren is pecking at a spider web. Cornell Lab says that wrens often put spider egg sacs into their nest box so the spiders will rid it of mites! (Click on arrow for slide show; use pause button for captions.)
The Tree Swallow (Tachycineta bicolor) spread its huge wings as it swooped in and out feeding its mate or young in June. Now the box seems to be just a stop-over spot as it soars and dives in the meadow beyond.
Thanks to Laurie Peklo, a member of the birding group who cleaned out the nesting boxes this spring, the Eastern Bluebirds (Sialiasialis) also found a home at Ilsley again this year.
A few weeks later, we saw a Bluebird fledgling in a tree, perhaps the male’s offspring. Baby bluebirds take a while to turn really blue, so I’ve also included a photo of a bit older one begging in our front yard. (Click on photos to enlarge; use back arrow to return to blog.)

When you reach the sign about Prairie Restoration, you’ll see that the center of the park is brown and mowed. Don’t worry. Ben VanderWeide, township stewardship manager, and his crew are just preparing the ground so that in the fall, it can be sown with native prairie plants – just as the eastern prairie was planted two years ago, and the north and west were planted last year. In a few years, we’ll have close to 50 acres of prairie in this park!
On every recent visit, a male Common Yellowthroat (Geothlypis trichas) has sung from the bushes on the hill in the center field. That’s why Ben left the greenery there when the field was prepared for prairie planting – to protect their young. The photo below, was taken in the spring when one male came a bit closer and really belted out his “witchedy, witchedy” song!
A Field Sparrow (Spizella pusilla) foraged in the grass of the trail on one of our birding walks. Its pink-ish beak matches its pink legs – an easy field mark for these little birds. Ben describes their rolling song as a bouncing ball.
Young Chipping Sparrows (Spizella passerina) and their elders forage there as well. Thanks to birder extraordinaire, Ruth Glass, for the identification! (Click on photos to enlarge.)
Ruth also identified the rather scruffy Eastern Wood- Pewee fledgling (Contopus virens) below.
We birders heard an adult one singing in the woods near the eastern prairie last week, but didn’t see it – as is often the case with singing Pewees. Luckily, one landed near our deck at home a few weeks ago, singing its name on a rising note – Pee-weeee! Nice to see one up close and personal!
In a clump of trees on the south side of the east prairie, an Indigo Bunting (Passerina cyanea) sang from a very tall snag on my last three trips to Ilsley. He must have a nest nearby. He’s so far up, singing his song in phrases of twos and threes, that it’s hard to even see he’s blue!
But my husband and I were lucky enough to have one fly down to a small tree near us while walking at Addison Oaks about ten days ago. Such a glorious bird!
As some of the birders exited the eastern prairie last Wednesday, they saw a very unusual bird, a Yellow-throated Vireo (Vireo flavifrons). I didn’t get a look before it flew – so here’s a lovely photo from a generous Creative Commons photographer at inaturalist.org, Donna Pomeroy.
We also saw the Red-eyed Vireo (Vireo olivaceus) again. Here’s a photo of this elusive bird by gifted local photographer, Bob Bonin.
Prairie Wildflowers – What a Sight!
In 2015, the eastern prairie was sown with native seed acquired through a grant from the U.S. Fish and Wildlife Service. It will take three or four summers of careful stewardship for these native, drought-resistant prairie plants to grow deep roots and reach full bloom. Although this is only their second summer, the native wildflowers are already carpeting the prairie with color.
Ben mowed the field once this year already and will mow once more in August. This relatively high mowing reduces the seed production of annual and biennial plants (like burdock, thistle and Queen Anne’s Lace) and allows sunlight to reach the prairie plants while they are small and growing roots. Look at just of few of the native wildflowers already coming up!
And we still have autumn flowers to look forward to!
That Carpet of Prairie Wildflowers Brought All Kinds of Butterflies!
What a glorious sight! All over Ilsley’s eastern prairie, butterflies float and flutter in and out of the colorful tapestry of native plants – sipping the nectar and enjoying the sunlight. The birders sighted a relatively uncommon black butterfly called the Spicebush Swallowtail (Papilio troilus), though it took a lot of talk and research to identify it correctly! Luckily, the next day I saw the very similar Black Swallowtail (Papilio polyxenes) and was able to study the photos to spot the distinctions between the two. Here’s a swallowtail identification link I found very useful. (Note that on this site, the butterflies’ names are above rather than below the photos, which can be confusing at first.)
This is the male Spicebush Swallowtail. Notice that he only has white dots along the edge of his forewing, a faint line of pale blue dots above and a wash of blue (or blue scaling) on each hindwing.
The Black Swallowtail has a larger second (or postmedian) row of yellowish spots above the row at the edge of its forewings and its more intense blue is contained in spots, rather than a wash of blue. It has a complete orange dot on each hindwing. This is the female, I believe, since her orange dots have a black center and the male’s are solid orange. Whew! Glad I had photos to help me!
My husband and I saw a third swallowtail flying high into the trees at Ilsley – the Eastern Tiger Swallowtail (Papilio glaucus). Here’s a photo from Bear Creek several years ago, just to remind you of its beauty, too. The female of this species can also be black! But that’s for another blog…
One hot morning, four different Monarch butterflies (Danaus plexippus) drank from blossoms on the Eastern Prairie. They didn’t leave their wings open for long when they settled; they only used them to move from bloom to bloom. Perhaps closed wings kept them cooler, since less sunlight would fall on their closed wings than on open ones. I’ve learned that dragonflies tip their bodies vertically to stay cool on really hot days for that reason.
Some of the birders spotted a Red Admiral (Vanessa atalanta) one Wednesday morning when I was off looking at the Spicebush Swallowtail. So here’s an older Bear Creek photo of one of those also.
On my last trip to the park, I saw a finger-nail-sized, triangular-shaped, white butterfly that I could not identify (help anyone?) and a tiny orange one that I believe is a Delaware Skipper (Anatrytone logan). To assess their size, consider that the little white one is under a Daisy Fleabane and the orange one is on a blade of grass! Interesting things come in small packages, eh?
A finger-nail sized white butterfly I could not ID.
A Delaware Skipper, I believe
A Spray of Tiny Grasshopper Nymphs, a Nice Big Carolina Locust, and a Widow Skimmer Dragonfly as well
On the path that crosses the center of the Eastern Prairie, you’ll see – and hear! – hundreds of tiny grasshopper nymphs jumping off the path. They sound like rain falling on the taller grass stalks! Only about an half inch long now, they’re hard to identify. My guess is they’re Red-legged Grasshoppers (Melanoplus femurrubrum). The larger one in the slideshow below is definitely a Red-legged but it’s still a nymph, too. These guys molt 5-7 times before reaching adulthood. The brown Carolina Locust (Dissosteira carolina)is much bigger, about 2 inches.
Of course no prairie is complete without dragonflies! Female, or possibly juvenile male, Widow Skimmers (Libellula luctuosa), with yellow abdominal stripes, hunted above the greenery last week. Adult males eventually develop a white wing band next to the dark one and their brown abdomens take on a bluish-white sheen as they mature.
Step by Step, Restoring Our Natural History
We all love local history, so it makes such perfect sense to restore our natural areas, too. At Charles Ilsley Park, we have an opportunity to see what our township looked like before European settlement, when Native American tribes lived on the rolling oak savannahs covered with tall grasses, wildflowers and widely spaced oaks. Even more importantly, natural areas restoration re-creates at least some of the rich diversity of plants, insects, birds and other wildlife that historically shared our green corner of the world. We’re on our way now to something very special here in Oakland Township. Come have a look!
