Jen Berlinghof is a graduate of Loyola University Chicago and The National Outdoor Leadership School, as well as a Certified Interpretive Guide through The National Association of Interpretation. Her work as an outdoor guide and naturalist has taken her from the canyonlands of Utah to the shores of Lake Superior. Since 2003, she has been rediscovering nature near her hometown and working as an Environmental Educator for the Lake County Forest Preserves in northern Illinois.
Around the first frost is the best time for spotting bears in the Lake County Forest Preserves in northern Illinois…woolly bears, that is! These fuzzy caterpillars succumb to a late fall wanderlust and can often be found traversing trails and roads, as well as climbing vegetation and nibbling a last few bites before winter sets in. They belong to the subfamily Arctiinae, commonly known as tiger moths. Their scientific name stems from the ancient Greek word arktos (“bear”), for the appearance of their hairy larvae.
The sun had set, the campfire was doused, and the food was stashed away for the night as my sons and I tucked ourselves into our sleeping bag cocoons, thoroughly exhausted in a way one can only be from a day spent entirely outdoors. Still, sleep would not come easily. The whirling drone of thousands of annual cicadas buzzed through the nylon walls of our tent loud enough to overpower our fatigue. I lay awake, thinking it odd the cicadas would be calling after dark, when I caught a hint of the rising full moon through the ceiling screen and realized they were staying up late to party with the extra light. One of my boys groaned, “Isn’t there anything that can stop these CICADAS?” As a matter of fact, the next day we found just the thing: a cicada killer wasp (Sphecius speciosus).
Last week, our Wetland Explorers summer nature campers went wild…in a good way! We were hiking along the Des Plaines River Trail when we came upon a major toad hatch-out. Hundreds of dime-sized toadlets took over the trail, prompting shrieks of excitement from the campers. The kids scurried around, scooping up handfuls of toads, trying to save all the hopping and popping amphibians from potentially hazardous bike tires and hiking boots along the trail.
Everywhere you look this time of year, animals are tending to nests during spring’s baby season. Squirrels are very active at this time with the bounties of spring. Food reserves from winter are low, and energy demands are high with young in the drey (their leafy, treetop summer homes) demanding to be fed. So, squirrels turn from their habits of digging for winter caches and begin eating buds, flowers, fungi and lichens. They will take advantage of almost ANY food source at this time of year!
Late spring and early summer are busy seasons for children visiting the Lake County Forest Preserves for pond study programs. The shorelines of ponds pulse with the excitement of students, nets in hand, ready to discover the macroinvertebrates teeming under the water’s surface. The most delightful find this season by students has to be what Henry David Thoreau once called the “submarine cottages” of caddisfly larvae.
Spring seems to be a bit accelerated this year in the Lake County Forest Preserves. Trillium are already blooming at Ryerson Woods. Yesterday, I even saw a tiger swallowtail butterfly, wafting its way through the dappled light of the forest. Both of these species are typically associated with mid-May. With earlier than usual spring weather comes earlier than usual “tick season.” Like the trillium and swallowtail, ticks are a part of our natural areas.
By learning more about ticks, along with some mindful actions before you head outside, interactions with ticks can be minimized so our enjoyment of the outdoors can be maximized.
Contrary to what many people think, ticks are not insects. They are arachnids. Like spiders, they have two body parts and eight legs. In addition, ticks have intricate mouthparts designed to bite and hang onto their host, which can be any warm-blooded animal in the area, including us. Continue reading →
