Length: typically 6.5-8.5 mm
Coelidia olitoria is a common species; adults are found in all but the coldest months in West Virginia.
Elsewhere in North America this species is wide-ranging, found in a majority of states and a couple of provinces.
As the images here show, the colors of this species vary from individual to individual. Nevertheless, looking at the shape of the head and eyes, and at the relatively short wings, no other species looks quite like this one.
Note that a number of sources use the name Jikradia olitorius for this species.
Also on the Insects of West Virginia site are images of the nymphs of Coelidia olitoria.
