These ground beetles, whose wing covers look as if they’ve been painstakingly sculptured, are introduced from Europe and are typically seen in our area in April and May. Peter noted that they were common on Mount Jumbo on the trail above the “L” …and that they appeared to be busy ensuring there was a new generation. They overwinter as adults, sometimes in groups, and are primarily nocturnal, often hiding under stones or other objects when not active. Snails, insects, and earthworms fall prey to these fast-crawling predators.
