Overview

Bembidion petrosum is a species of ground beetle in the family Carabidae. It is found in North America, Europe, and temperate Asia. The species breeds in the summer and hibernates as an overwintering strategy. They are often found in riparian habitats, aggregating beneath stones.

Bembidion petrosum, the älvstrandlöpare, is declining primarily due to habitat loss and degradation of its specialized riverine environments. Human activities including river regulation, hydroelectric development, and changes to natural flow regimes have severely impacted the dynamic gravel and sand substrates this species requires for survival.
