Leaf-footed Bugs

Acanthocephala terminalis Acanthocephala terminalis

What are they?

A group of Hemipteran bugs that are best distinguished by the swollen mid-section to the hind leg which often forms a distinctive, leaf-like or flag-like segment. They vary considerably in size, from tiny, easily overlooked species to some that can reach almost an inch in length when adult. These insects fly readily if disturbed, making them often difficult to approach and observe. Like the related stink bugs, insects may release a noxious odor if handled.

Identification

Many species in this group are fairly easy to identify, based on details of leg structure and overall shape, color and markings.



     Acanthocephala terminalis

Adults of this species are one of the largest leaf-footed bugs in our region, growing up to almost an inch long. They are often encountered in wooded areas and give a distinctive buzz when they fly off. Note the adults' bright orange tips to the antennae.
