Leaf-footed bugs (Hemiptera: Coreidae) get their common name from the wide, flat projections found on the hind legs of the adults of many species. Adults of many other species lack this feature, as do the young nymphs like the one pictured here.
I found this nymph along the edge of the River Raisin near Blissfield, Michigan last week. It was crawling around on the fruit of a wild cucumber (Echinocystis lobata, Cucurbitaceae). Although I didn’t observe it feeding, these insects do feed on plant juices and it may have been sizing up the plump fruit, leaves, or stems for a meal. A number of leaf-footed bugs like Euthochtha galeator, Anasa tristis, and Anasa armigera do feed on cucurbits.
