Gyrinus substriatus (Stephens, 1828)
More commonly known as the Whirligig Beetle, Gyrinus substriatus is one of several UK species. It is also the commonest of the three and was found present in numbers (150+) on the surface of the pool on Budby South Forest in late August 2009. The beetles can go underwater, but spend most of their time on the surface, where they feed on small insects that fall onto the water. Known to be widespread and common across Nottinghamshire, thanks to the recording work of Bob Merritt.
