Bolitotherus cornutus
''Bolitotherus cornutus'' is a North American species of darkling beetle known as the forked fungus beetle. As a holometabolic insect, its life cycle includes four life stages: egg, larva, pupa, and adult. All life stages are associated with the fruiting bodies of a wood-decaying shelf fungus, commonly ''Ganoderma applanatum'', ''Ganoderma tsugae'',〔 and ''Ganoderma lucidum''.
== Description ==
Adults are brown, armored beetles, about 1 cm long, that are sexually dimorphic with respect to the presence of horns. Females lack horns. Males use their two sets of horns, clypeal and thoracic, to compete for mates. Unlike many species of scarab beetles that exhibit male dimorphism for horns with major and minor morphs,〔Emlen DJ (1996) Artificial selection on horn length body size allometry in the horned beetle Onthophagus acuminatus (Coleoptera: Scarabaeidae). Evolution 50: 1219–1230. doi:10.2307/2410662〕 male ''B. cornutus'' possess a continuous range of horn and body sizes.〔Conner JK (1988) Field measurements of natural and sexual selection in the fungus beetle, Bolitotherus cornutus. Evolution 42: 736–749. doi:10.2307/2408865.〕 Adult beetles are active at night, but may be found during the day on the undersides of their host fungi.
