Fast forward to summer 2021. The hum continues to reverberate after multiple sightings of this keystone species were documented across the county from Flint Creek to Wadsworth Savanna in Wadsworth. While summer’s the height of hive activity, the shoulder seasons—usually defined as May, June, September and October—might be key to the success of the rusty patched bumble bee. This is partly due to the timing, or phenology, of the species’ lifecycle. It’s one of the first bees to emerge in spring and the last to enter hibernation in fall.
Many years ago, while hiking through a prairie at dusk, I saw a stalk of delicate white flowers. They seemed to rise and hover above the surrounding plants like a group of little dancing ghosts. This was the first and last time I ever saw an eastern prairie fringed orchid (Platanthera leucophaea). Due to its dwindling numbers and hidden habitats, this rare plant has reached almost mythical status—a holy grail of sorts in the Midwest. We’re thrilled that this endangered native orchid seems to be gaining a foothold in the Lake County Forest Preserves, which are home to some of the largest remaining populations. Just this month, one of our restoration ecologists discovered an orchid in bloom (photo below). It was found at one of the preserves known to provide habitat for this species but is the first documentation of a population at the site.
Last week while visiting Lyons Woods, I noticed that a large patch of garlic mustard was quivering. When I got closer, I found that it was not the breeze making the plants sway, but rather a huge group of red admiral butterflies (Vanessa atalanta) flitting from flower to flower. In many areas, all you have to do is walk out your front door to witness the population explosion of these ubiquitous butterflies that is sweeping the northeastern United States this spring.
During a training hike for volunteer nature guides last week, a fellow naturalist pointed out a series of pea-sized holes in the ground. I walk along this same trail regularly and had never noticed them. As our group stooped around these holes, shivering on this cold but sunny spring morning, a tiny head crept slowly out of the one of the holes. It was the head of a mining bee! Continue reading →
