In southern Quebec, leaf-footed bugs are usually small, stocky, dull-coloured bugs. The membrane of their forewings is marked with parallel veins.
In tropical species, the tibiae on the hind legs are sometimes very broad and leaf-shaped, hence their common name of leaf-footed bugs.
When disturbed, some of these insects release a foul-odoured substance similar to that emitted by stink bugs, produced by glands on the thorax.
The adults are 10 to 20 mm long.
