Rhamphomyia marginata is a fly from the family of dance flies (Empididae).
features
The flies reach a length of 4–5 mm. The thorax is colored gray and has three dark longitudinal lines. The females are distinctive because of their wings. The triangular transparent wings are colored dark brown along the rear and outer edge. When sitting, the wings overlap with the exception of the rear wing tips and a narrow side edge. The males, however, have a normal wing shape and no darkening of the wings. The eyes touch each other in the male, while they are separated in the female.
distribution
The species is widespread in Europe. The occurrence ranges from Scandinavia and Great Britain in the north to Central and Western Europe.
Way of life
The flies are predatory, but also ingest plant nectar. They live in mixed and deciduous forests. They are observed from the end of April. In contrast to other dance flies, the females of this species form swarms into which the males fly to mate. They usually carry a captured insect.
