The green-gloss gun fly ( Microchrysa polita ) belongs to the gun flies (Stratiomyidae).
features
Shiny green gun flies can reach a body size of four to five millimeters. Their bodies usually have a metallic green shine. The abdomen is slightly flattened and protrudes laterally from under the folded wings.
Feelers such as feet ( tarsi ) and thighs ( femora ) appear black-brown, the lower legs ( tibia ) yellowish. The wings are transparent to slightly grayish or brownish and show a fine veining. They tower above the end of the abdomen. Microchrysa polita is one of the gun flies that lack the eponymous "weapons", the thorn-shaped extensions of the scutellum of the middle back segment .
The head has large complex eyes . In female adults they are separated by a large forehead, in males the eyes can almost touch.
There may be a risk of confusion with Chloromyia formosa , which is, however, significantly larger and whose complex eyes are hairy.
The similar Microchrysa flavicornis and Microchrysa cyaneiventris , which often occur in the same habitats , can be seen in the color of the anterior tarsi (in M. polita black, in the others partly yellow) and the antennae (in M. polita pure black, in the others the first Yellow link).
Occurrence
Microchrysa polita is widespread in the Holarctic . It occurs throughout Europe and North Asia . The occurrences in North America (southern Canada and northern USA ) are believed to have been introduced by humans ( neozoon ).
In Germany, the shiny green gun fly is one of the most common species of the Stratiomyidae family. They adults can be observed from March to September.
Way of life
Pollen and nectar form the basis of nutrition for adults. Umbelliferae and hawthorn are preferred. Female adults of the gun flies lay their eggs in early summer on rotting substrate like compost . The maggots feed on vegetable matter in the state of rotting. A keratinized (sclerotized) larval skin protects them against excessive drying out, but places that are more humid and warm are sought out. The maggots overwinter and pupate in their last skin, which sclerotizes. Adults hatch in March or April.
Since Microchrysa polita is not considered endangered, it is also not under nature protection.
