Eriothrix rufomaculata is a fly in the family Tachinidae.[2]


This species is present in most of Europe and in European Russia. It can be found in Britain, where it is quite widespread throughout the country. It is also found in Ireland.[3]


These rather common flies mainly inhabit hedge rows,[4] grasslands or sunny rough ground, meadows, ruderal areas and fields.[5]


Side view

Eriothrix rufomaculata can reach a length of 5–10 millimetres (0.20–0.39 in) and a wingspan of 13–15 mm.[4] This bristly species shows a greyish thorax with four narrow black stripes and a prominent but quite variable orange patches on the sides of its cylindrical abdomen, separated by a dorsal black line. Its face is silvery, with a protruding mouth edge. The legs are black. Wings are slightly shaded, yellowish at the base. Vein-m is petiolate and costal spine is longer than vein r-m.[5][6][7][8]


Eriothrix rufomaculata is a univoltine species. Adults can be found from July to October. They are flower feeders, visiting in particular members of the Umbelliferae (especially Heracleum sphondylium) and Asteraceae. The species is parasitic, the larvae developing inside the subterranean larvae of moths, especially of crambid moths (Chrysoteuchia culmella,[2] Crambidae), tiger moths (Ammobiota festiva, Erebidae), lappet moths (Dendrolimus pini, Lasiocampidae) and ermine moths (Yponomeutidae)).[4][5][9]
