Dead twigs or branches (Mound and Marullo 1996).
The head is elongate and the cheeks often have prominent warts. The eyes are bean shaped and large. The posterior setae on the cheeks are about the same size as other cheek setae, and the postocular setae are well developed. The intermediate antennal segments are vase shaped. The mouth cone is large and pointed. The pronotum is hexagonally reticulate and has stipple-like dots. One or two well-developed epimeral setae are present on each epimeron. Males and females are macropterous. The forewings are broadened and occasionally are indented in the middle. The abdomen is reticulate and the pelta is small. Each abdominal tergite has 2 or 3 pairs of wing holding setae. The tube is moderately long and the anal setae are not quite twice as long as the tube (Stannard 1968).
The second instar larvae have head horns (Stannard 1957, Heming 1991).
Species in this genus feed on fungal hyphae (Mound and Marullo 1996).
Members of this genus can be found in Alberta (Chiasson 1986), and across the holarctic region (Stannard 1957).
