The peacock fly ( Callopistromyia annulipes ) is a decorative fly from the subfamily Otitinae . The specific epithet annulipes means "with curled legs", the common name is the translation of the English name peacock fly and refers to the striking wing movements of the male.
The genus Callopistromyia is originally only represented in the nearctic fauna with two species . The peacock fly ( Callopistromyia annulipes ) has now also been found in Europe, where it was introduced as a neozoon and is spreading. The genus was named Callopistria by Loew in 1873 , but this name was already given to a genus of butterflies and therefore had to be changed.
Characteristics of the imago
The fly reaches a body size of 3.5 to 5.5 millimeters. The body is dull gray with numerous brown tomentose spots .
The head is slightly higher than it is long and about 1.5 times as wide as it is high. It narrows towards the front. The eyes are only very slightly higher than they are wide. The forehead is flat and without a central keel and arched inwards when viewed from the side. The head shield is moderately strong and slightly curved outward when viewed from the side. The antennae are of medium length and spaced apart at the base, the antenna bristles are bare. The cheeks are less than half of eye level.
The chest is longer than it is wide. The oval wings are 2.1 times as long as they are wide. The wing vein radius 1 is bristled briefly, in the middle area (discal cells) the wings are covered with numerous small dark and transparent spots, in the area of the front edge larger spots appear. The spots are loosely distributed and do not form any transverse bands. The gray and continuously matte top of the chest is covered with microscopic black hair.
The abdomen is also darkly spotted. The sides of the abdomen are hairy. The rails are at the base and near the tarsi yellow and curled three times dark.
biology
The animals were found on dead or dying wood from various trees ( Acer negundo , Populus deltoides , Robinia pseudacacia ). The larvae eat the excrement of wood-boring insects. The males flap their wings up like a peacock. The flies can be seen from the beginning of April. They often hang out on tree trunks.
distribution
The species is originally native to North America and has been reported from Canada and the United States . Numerous new finds suggest that it is spreading there too. The first published report from Europe dates back to 2007 and relates to the discovery of a female in a vineyard in southern Switzerland. The first reports from Germany should be in Hanhofen in 2006 , in Bonn in 2008 and in Rottenburg and Gelsenkirchen in 2009 . The request for identification of the taxo image was classified by the Diptera Forum as the first report from France (July 15, 2011). The species was first observed in Slovakia in 2016.
