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

Chrysotoxum verralli Collin, 1940

Biology: This species has been reared from larvae found in a nest of the ant Lasius niger. Also, pupae have been found under a stone, and females seen ovipositing, close to the entrances of ants nests. Found on well drained soils usually near the shelter of trees or hedgerows. Typical situations include grassy places in scrub, woodland rides and glades or on the fringes of heathland. They are often seen resting on vegetation, and occasionally visit flowers such as Rubus and Rosa

Distribution: Mainly southern England, but extending through the Midlands in a broad band to Merseyside and South Lancashire. Whilst very local, it can be abundant where it occurs
