Dallas’s leaf-footed bug
Order: Hemiptera (True Bugs)
Family: Coreidae (Leaf-footed Bugs)
▶Scientific name: Anoplocnemis dallasi Kiritshenko
▶Size: Adult body length 18.5–24 mm
▶Host plants: Soybean, wild soybean, lespedeza, and other legumes

Adults measure 18.6-24mm in length. The body color is mostly dark brown to black, though some individuals may appear lighter brown. The membranous part of the forewings is always dark brown, while some may look grayish due to dense yellowish-white hairs scattered on a black background. The underside of the body is also dark brown.
The rostrum (beak) is short, four-segmented, and reaches only as far as the base of the mid-lef. The head is small, with the antennal based touching at the front of the head. The pronotum has raised ridges near both the anterior and posterior margins, and the posterior corners are slightly elevated. The scutellum is small, triangular, and pointed at the tip. The forewings are narrow, extending well beyond the end of the abdomen, with long membranous portions showing nearly parallel veins.
In males, the fermora of the hind legs are thickened into a triangular shape, while in females they are more curved and swollen; both sexes have a single inner spine at the end of the femora. Adults suck sap from young shoots and pods of soybeans, lespedeza, and other legumes. They usually appear from August to September.
