Length: typically 3.6-3.9 mm
The margin between the head and the pronotum is sinuate in the genus Agalliopsis, with the head a little longer near the eyes than at the center.
Adults are active in all the warmer months in West Virginia.
Shaw (1976) at Iowa State University studied the sound production of an Agalliopsis species, A. novella. The male begins by emitting "common sounds" which are unique to the species. If receptive, the female responds with the common sounds. The two then alternate producing these sounds, and eventually the male moves alongside the female.
At the side of the female, the male soon attempts copulation "by leaping onto her back." But just before making this leap, the male emits the precopulatory sound, "a sequence of irregular buzz-like pulses" accompanied by a vibrating of his wings. If the mating attempt is not successful, the male may start over with the common sounds.
