Thaumatomyia notata

A very tiny (2.5 mm) yellow fly with dark stripes on the thorax. Note this is a tentative identification. Other chloropids, e.g. Chlorops pumilionis have similar markings on head and thorax and for this reason the image is placed in a red box.

Mainly in flower meadows but sometimes it enters homes in large numbers and for this reason has been nicknamed Yellow Swarming Fly.

Spring and summer.

Larvae predaceous on aphids.

Widespread in England and Wales, but difficulties of species identification means that true status is uncertain.

Status in Leicestershire and Rutland is not known.
