About Psila fimetaria (Linnaeus, 1761)
Psila fimetaria grows to a body length of 7.7–8.8 millimetres (0.30–0.35 in). Its basic body color is yellow-red, and the body is covered with short black bristles. The abdominal tergites of this species are sometimes distinctly browned. The head is red with a black ocellar triangle. The eyes are large and kidney-shaped. The palps are yellow. The antennae are short and red; the third antenna segment is subconical, slightly thicker than other segments, and black at the base. The arista has longer pubescence. The legs are long and yellowish, with slightly dark tips on the tarsi. The wings are transparent, with a slight yellow tint along the anterior edge. Like all species in the genus Psila, male Psila fimetaria do not have thickened hind femora, and females have only a simple ovipositor. This species is very similar to Psila merdari, but can be distinguished by two features: the hairs beneath the second antennal joint are longer, and the third antennal joint is darkened on the outer side at the base of the arista. This species is distributed across parts of Europe including Belgium, Great Britain, Czech Republic, Denmark, Germany, Hungary, Italy, Lithuania, Slovakia, and Ireland, as well as in Russia and North Africa. These common flies live in woods and forests, bushes, and among herbs. They are especially found in damp places with lush vegetation, along hedge rows, and among growing crops.
