This species is closely related to, and resembles, Aneugmenus species. The body is black and the legs are black, marked with white. The hind tibia is black apically and the tarsal claws have a small subapical tooth. The head above is covered with small tubercles, or warts, and the frontal area has a defined raised hexagonal platform.

Birka cinereipes larvae feed on water forget-me-not. Initially larvae feed on the underside of leaves eventually eating the whole leaf. Pupates in the ground litter layer.
