I often see these tiny, colourful flies in one particular spot in a local field. They are known as ‘Fruit Flies’ or ‘Picture-winged Flies’. A yellow coloured gall fly with dark patterns on its wings. Length 4 to 5mm.
The larvae feed on Burdock causing galls.
It flies June to August, and is found where the foodplants grow, meadows and gardens.
Common and widespread in the south of England, rarer further north.
