Species Description

Widespread and fairly frequent throughout the UK. Habitat includes: gardens, parks, allotments, churchyards, hedgerows, scrub, woodland etc. Flight period: May to September. Length: 5 - 8 mm. Food Plant: Various members of the Rosaceae family including: Crataegus, Fragaria, Prunus, Pyrus, Sorbus etc. Very similar to C. brullei but has translucent instead of darkened wings and the abdomen lacks the brown spot in the middle of the first tergite. Also the ridge which separates the median facial fovea between the antennae from the frontal basin above is more or less broken rather than continuous.
