The species fly from May to June. The lifecycle is not known but the
larvae are thought to be external parasites that feed on the
pupae of other beetle
species including
Amara convexiuscula and a
staphylinid beetle,
Tasgius ater (Gravenhorst, 1802). When disturbed, the species shoot liquid from two
glands through their
anus. Since one of the glands contains
hydrogen peroxide and the other
hydroquinone, when two the contents mix with enzymes in a "firing chamber", the liquid explodes, and harms the attackers. ==Habitat==
