Filmed near Mountain Lake Biological Station, Pembroke, Virginia. This video (HD, IR) depicts courting Bolitotherus cornutus (forked fungus beetles) on fungal bracket. Males typically court females for several hours with repeated bouts of vigorous shaking episodes. Males mount a female head to abdomen while gripping the dorsal surface of females with his legs. Females have complete control over a successful spermatophore transfer due to the presence of a restrictor plate over her genitalia.
