This bug is named for its leaf-like expansion of its hind legs. The adults grow to about 1 inch long (25 mm). They are dark gray in color, with orange to yellow terminals of their antennae. The nymph shown in image 2 is probably a 3rd instar (developmental stage).
Both adult and nymph feed on plant juices. They are fairly common in moist hollows and on the floodplain at both nature centers.
