Gonioryctus species are large, 4.0-10.0 mm, with the majority ~7 mm. They are diverse morophologically and ecologically.  David Sharp, in the Fauna Hawaiiensis, called Gonioryctus "the perfect insect". By this he meant that their adult stage is extremely short. Specimens are often collected at lights at dusk in pairs of 1 male and 1 female. They are also found in wood, under bark, in rotting vegetation, and in fresh flowers.
