The Western Conifer Seed Bug is relatively new to this region being first noticed in the north eastern part of the country in the late 1990s.
It is a true bug (Hemiptera) of the family Coreidae, leaf footed bugs, with the scientific name: Leptoglossus occidentalis. Normally it overwinters under bark or in bird or animal nests. Unfortunately for us, and fortunately for the bugs, our homes also make a good overwintering spot. This makes this insect kind of a pest. They do no harm. They do not bite, although being true bugs they have piercing sucking mouth-parts and if handled they may try to stab. They use their mouth-parts to pierce the scales of conifer seeds and suck out the endosperm, the good part of the seed. They do no damage to the trees and the seeds can still develop. Please be aware if you squish them they let out a unpleasant odor, so it is best not to kill them but remove them from the house while alive.
This is a handsome bug, reddish brown with a black and white or yellowish pattern under its closed wings (elytra). It has small spikes on the upper hind legs and widened, leaf-like projections on its hind legs.
