 Crawling water beetle - Wikipedia, the free encyclopedia
The crawling water beetles are a family (Haliplidae) of water beetles who swim poorly using an alternate motion of the legs, and therefore prefer to get around by crawling.
These beetles are generally oval in shape, with lengths from 1.5 to 5 mm, and generally yellowish to light brown in color, frequently with light and dark patterns dotted with 10 or more rows of punctures.
The eyes are distinctly protruding from a smallish head, and the legs have long swimming hairs, but the family's most distinctive characteristic is the large coxal plates underneath, which extend back to cover most of the abdomen, and are used as air storage supplementing the air carried under the elytra.

 FINAL RULE: HUNGERFORD'S CRAWLING WATER BEETLE, U.S. Fish & Wildlife Service   (Site not responding. Last check: 2007-11-04)
Brychius hungerfordi is a small (4.20 mm), distinctive, yellowish brown beetle with irregular dark markings and longitudinal stripes on the elytra, each of which is comprised of a series of fine, closely spaced and darkly pigmented punctures.
Because adult beetles must swim to the surface for air, they are vulnerable to predation by fish, tadpoles and other aquatic insects (Hickman 1931; Wilsmann and Strand 1990).
The beetles are thought to live longer than one year and to overwinter as larvae in the dense aquatic vegetation at the stream's edge (Wilsmann and Strand 1990).
