Species account from Provisional atlas of British hoverflies, Ball & Morris, 2000.

Chrysotoxum cautum (Harris, 1776)

Biology: The larvae of this species remain unknown, but the genus is thought to be associated with ants, perhaps feeding on ant-attended root aphids. Adults are usually found in well drained grassy places, often near shelter such as woodland edge or hedgerows where they visit a wide range of flowers. Seen in flight, they have a striking resemblance to a social wasp

Distribution: This species occurs south and east of a line from the Severn to the Humber (an almost complete reversal of the range of C. arcuatum), except for scattered localities along the coast of Wales and the coast of north-west England. It is locally abundant, especially in southern-central England
