Big-legged Bug
A large, dark coreid bug found in eastern North America with prominently expanded hind tibiae. The hind femora of males are greatly swollen with large spines. It feeds on a wide variety of trees and shrubs.
Did You Know?
The exaggerated hind legs of males serve as weapons and signals of fitness, with larger-legged males winning more fights and mates.
Common Water Strider
A slender dark brown insect that skates across the surface of streams and ponds using water surface tension. Its long middle and hind legs distribute its weight over the water film.
Did You Know?
Tiny hydrophobic hairs on its legs trap air and repel water, allowing it to stand on the surface without breaking through.
