Acanthocephala terminalis

Acanthocephala terminalis is a species of leaf-footed bug in the family Coreidae. It is found in North America.



Description
Acanthocephala terminalis is usually around 18-25mm long with a dark gray to black color. They have large femora (or thighs), the fourth (and last) section of their antennae have orange coloration, and the tibia (or end) of their hind legs have a flat, leaf-like, appearance. Both juveniles and adults produce defensive scent from their thorax as a repellant.

Range and habitat
Acanthocephala terminalis is usually found in the eastern half of the United States and parts of southeast Canada. They will usually live in woodlands, fields, and meadows.

Life cycle
Acanthocephala terminalis will begin its mating period in late spring, and females will lay eggs on host plants. Once the juveniles hatch they will molt five times before they reach adulthood. With each molt the nymphs will slightly more resemble the adults. Acanthocephala terminalis overwinters and are seen in groups before and after meeting in overwintering quarters.

Sexual dimorphism
Sexual dimorphism is relatively limited, although males typically have thicker, curved hind legs and will have fewer spikes, while body size remains relatively stagnant.

Diet
Acanthocephala terminalis will eat the sap of trees and other plants without causing damage. Notable plants eaten are staghorn sumac, riverbank grape, and ninebark.
