• Araeopidius monachus

  Araeopidius monachus is the sole species in the subfamily Araeopidiinae within the beetle family Ptilodactylidae. It is endemic to western North America, where adults are rarely encountered. The species exhibits an unusual three-year life cycle among beetles, with larvae feeding on woody material while adults appear to be non-feeding. Its biology remains poorly understood due to the scarcity of specimens and limited field observations.
