Scathophaga lutaria
Typically a rather large species with a strong dark streak on the outer surface of the front femora (similar in this respect to S. furcata which has a bare arista), however, as with many Scathophaga, smaller specimens with colour characters poorly developed are not infrequent. In the male the greyish thoracic dorsum contrasts with the yellow humeri and scutellum. Abdomen yellow with hind margins of the tergites darkened. Most readily distinguished from S. inquinata by examination of the male 5th abdominal sternites although care is needed because the abdomen often shrivels in dried specimens and it can be quite difficult to work out which bit to look at. Wing length: ♂ 4.7 - 7.1 - 8.8 mm (20); ♀ 5.0 - 7.0 - 8.6 mm (12).
Widespread and not uncommon, but not usually found in abundance. Often in woodland or other sheltered places.
World distribution: Palaearctic: Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Norway, Poland, Slovakia, Spain, Sweden, Switzerland; Russia: northern European regions, Karelia, east Palaearctic; North Africa.
