The family of Coleoptera known as Haliplidae or the Crawling Water Beetles includes small sized beetles that may be readily recognized by the oval shape and the ten segmented filiform antennae. They are usually light brown or yellow, spotted with black, in color. The elytra have rows of punctures and are widest near the front.
