Adults have been found in ant nests (4), rodents nests, feces, malt-baited pitfall traps, and at black lights. (1)

Walter et al. (1938) report, "This adult scarabaeid was found apparently freshly emerged on March 14 in an abandoned [Atta texana] chamber containing waste material. In this same chamber were a number of pupal cells containing prepupae that may have been of this species. The walls of the pupal cells were composed of a mixture of earth and waste material firmly cemented together. They were quite hard, nearly round, and about an inch in diameter. Specimens taken for rearing were lost when the underground rearing chamber became flooded one night during a heavy rain." (4)
