• Pleocoma

  rain beetles

  Pleocoma is the sole extant genus of Pleocomidae, a family endemic to the Pacific states of North America. These beetles are notable for their extreme subterranean lifestyle, with adults emerging only during fall and winter rains to mate. The genus name derives from Greek words for 'abundant hair,' referring to the dense ventral hair covering. Adults are non-feeding, while larvae are root-feeders with exceptionally long development periods of up to 13 years.
