Detailed explanation-1: -Bembidion zephyrum is a species of ground beetle found in British Columbia, Canada and California, Oregon and Washington of the United States.

Detailed explanation-2: -The group of insects that belong to the order Coleoptera is known as beetles. As of now, beetles are the largest order of insects.

Detailed explanation-3: -Introduction. There are more species of beetles than of any other kind of insect. They constitute the largest order of insects-Coleoptera-which includes more than a third of a million recognized species. In fact, the beetle order is the largest order in the entire animal kingdom.

Detailed explanation-4: -Pupal: This stage of the beetle life cycle is where the greatest change in form takes place. The worm-like larvae form the pupa or cocoon as it often called, then lay dormant.

Detailed explanation-5: -Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. Beyond that it is difficult to make broad generalizations about the aquatic Coleoptera. Most adults and larvae are substrate dwellers, but some are efficient swimmers (e.g., larval and adult Dytiscidae and Hydrophilidae).
