This fly is unusual in being almost completely orangey-yellow.

Phaonia pallida is a very similar orange muscid. Females can be separated by the frontal vitta (area between eyes) which is orange in P. pallida but dark in T. diaphanus. Males will generally need microscopic examination.

Woodland and well wooded areas.

Usually seen from summer through to late autumn/early winter.

Larvae are carnivorous on other larvae in fungi.

Widespread and fairly frequent in England and Wales.

Fairly common in Leicestershire and Rutland
