Melangyna quadrimaculata - Melangyna quadrimaculata

Description

The males are unusual in having only four spots on the abdomen (hence the scientific name), this together with long pale hairs on both the thorasic dorsum and pale yellow scutellum are identifying features. The eyes are also very hairy. Females are distinct in being entirely black with a shape and venation that quickly separates them from spring-flying Cheilosia or Pipiza.
