Life History. Many are often collected at light. Others come frequently to dung baited pitfall traps, which implies they are surface generalists as adults. A few are rodent or tortoise burrow specialists. Most seem to prefer sandy substrates, and may be detritivores.
Larvae. The larvae of B. stercorosus and B. troglodytes are described in Ritcher (1966).
