The morning temperatures are in the mid 70’s, under sunny skies as Caroline and I hike with our friends, Jeff and Maria Reynolds on a nature trail in Giant City State Park, near their home in Carbondale, ILL,500 miles SW of Alma. Soon, I come upon a resting Harvestman. One of 60 species of North American Daddy-long-legs, this one is known for its uncanny ability to detach a limb to evade predators, a self-defense tactic accompanied by a twitching motion to distract the threat while it escapes. Its diet is diverse, consisting of small invertebrates, decaying vegetation, and fungi. Up ahead, I spot white blossoms of Indian Physic and purple blossoms of Limestone Wild Petunia. Each Petunia flower only lasts for a day, but the plant has a very long flowering period, starting in early spring and going strong through the fall. It is named because the plant is primarily found in areas of the state underlain by limestone. Next, I follow the trail between giant walls made of sandstone. This sandstone was formed over millions of years as sandbars and dunes in a prehistoric river delta of sediments were compacted and cemented together. After that, earthquakes uplifted, cracked, and crumpled the earth in this area to form hills, bluffs and the giant cracks or fissures in the rock. Subsequently, erosion by wind and water etched the bluffs by removing softer minerals, forming pocket-like depressions, called honeycombs. Adding to the slow weathering of the bluff walls are the mosses and lichens that cover rock surfaces, including this Orange Wall Lichen. Around the bend, I spot a small Black Bee fly. Bee flies are a family of true flies and are not bees at all. Lacking the ability to sting or to bite, their bee mimicry helps them avoid many would-be predators. Near the path, I observe a patch of May Apple plants with one displaying a one-inch, green “apple”. All other parts of the plant (e.g., rhizomes, leaves, stems, and unripe fruit) are considered toxic to humans. After ripening the edible fruit is soft, yellowish and tastes like a mix of pineapple and Starburst candy. Wildlife that have been observed eating the fruit, include raccoons, deer, and squirrels. Continuing down the trail, birdsongs come from all directions. One originates from a Red-eyed Vireo (stock photo) another from a Carolina Wren (stock photo). Nearing the car, I look down in a stony creek bed to see a Question Mark Butterfly with partially open wings. These butterflies are quite unusual because the undersides of these wings are camouflaged and resemble dead leaves (stock photo) allowing them to hide from predators.
