I’ve spent many days this summer living the “lake life,” from the sandy dunes of the Great Lakes to the cattail-studded coves of inland waters. The waterways found within the Lake County Forest Preserves in northern Illinois have been especially rewarding. Each shoreline has provided unique glimpses of wildlife, including an osprey (Pandion haliaetus) diving full throttle to catch a fish at dawn, and a red fox (Vulpes vulpes) pouncing on prey hidden among the beach grass at dusk.
Also present at every waterway this summer has been the jewel-hued, common green darner dragonfly(Anax junius). These ubiquitous insects effortlessly nab multitudes of mosquitoes on the wing. While the monarch butterfly (Danaus plexippus) reigns in our minds when it comes to insect migrations, recent research reveals the green darner takes a multi-generational, miles-long journey of its own each year.
It comes as no surprise that in a place named “Lake County” you are never more than a stone’s throw away from water. Lake County, Illinois is scattered with thousands of acres of wetlands, dotted with over 170 lakes and rivers, crisscrossed with 400 miles of streams, and bordered by massive Lake Michigan. This year at the Lake County Forest Preserves, we are celebrating this wealth of water by exploring how Water Connects Lake County through educational programs and recreational opportunities.
One way water connects the critters of Lake County is through the magic of metamorphosis. Ponds, streams and other wetlands host and hide well-known animals in surprising forms. Take a look at the picture below. This is a type of insect found in most local bodies of water. Can you identify this creature?
