Pleocoma hirticollis
rain beetle
Pleocoma hirticollis is a species of rain beetle in the family Pleocomidae, a group of scarab beetles endemic to western North America. The species is active during autumn and winter rains, emerging only when soil is saturated. Three subspecies are recognized: P. h. hirticollis, P. h. reflexa, and P. h. vandykei. Like other Pleocomidae, adults are sexually dimorphic and do not feed.
