I have been fascinated with ground beetles of the genus Bembidion since I was a teenager. This large genus (over 1250 described species) and their near relatives are small beetles, but they have elegant shapes, and, in some, bright or complex colors. They are common predators on the shorelines of cold temperate bodies of water, and in some drier habitats, too. I find them not only beautiful, but fascinating in their diversity of structure.
