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

Platycheirus ambiguus (FallÚn, 1817) Melanostoma ambiguus FallÚn in Coe (1953)

Biology: The larvae feed on aphids on trees and shrubs. They are most often found visiting spring blossom, especially Prunus spinosa and flowering Salix in sunny, sheltered situations such as woodland margins and large hedgerows. According to Speight (1998) there is a strong association with scrub: Males hover close to flowering shrubs, often in amongst the branches, whilst females are found at the flowers or in the immediate vicinity

Distribution: Although a very local species, it can be abundant in suitable localities. It is widespread in England and Wales north to Northumberland, but more frequent towards the south-east
