The beaked hover flies ( Rhingia ), also known as snout flies , are a genus of hover flies (Syrphidae), which are particularly characterized by the beak-shaped extension of the face area.
features
The beaked hover flies are medium-sized with eight to eleven millimeters in length. The body is stocky and, unlike many other hoverflies, has no wasp-like black and yellow markings. The most striking feature below the eyes is the clypeus drawn out into a beak-shaped structure , on the underside of which the mouthparts lie. The wings are often yellowish-brown.
Way of life
The animals can be found as flower visitors from May to September on meadows and pastures, whereby they prefer flowers with deep calyxes. They are mainly found on purple and blue flowers, especially on oregano , Günsel , buttercups , cranesbills or dead nettles .
The eggs are laid on blades of grass above cow dung . The larvae are coprophagous in cow dung and camouflage themselves there with dung particles.
species
There are three types of Rhingia in Europe :
- Common snout hover fly ( Rhingia campestris )
- Mountain-beaked hover fly ( Rhingia borealis )
- Rhingia rostrata
