Suillia bicolor (Zetterstedt, 1838)

Suillia bicolor is a Palearctic species of Heleomyzidae. The sctellum is covered with light, fine, scattered hairs. The wing venation is characterized by the presence of small spines on the costal vein. The first pair of legs of the male has the first tarsal segments equipped with a spike of a triangular shape and a width smaller than the width of the segment. The female's abdomen has a seventh segment that is longer than the sixth. The reproductive organs of females have three irregularly jagged, cylindrical in outline, seminal receptacles narrowly curled at the apex. For terms see Morphology of Diptera.
