BotW: Bembidion poculare

Bembidion poculare

Bembidion poculare

This Bembidion is common in oak woodlands in southern Arizona.  It is not directly associated with a body of water (which is unusual for a Bembidion), instead living between oaks and mesquite trees where the soil is slightly damp (perhaps in a valley, above a river bank) and there is some leaf litter on the ground.  For example, it is common in Walker Canyon, the same locality that is pictured in the post on Chlaenius pimalicus.

B. poculare is a member of subgenus Cyclolopha.  A very closely related subgenus, the subgenus Bembidion itself, has several species that live in similarly open, dry environments.
