Systematics
Order : Fly (Diptera)
Subordination : Flies (Brachycera)
Family : Hoverflies (Syrphidae)
Genre : Eristalinus
Type : Shiny rotten mud hover fly
Scientific name
Eristalinus aeneus
( Scopoli , 1763)
In southern Europe, especially female animals often have five gray longitudinal lines on the mesonotum , similar to the black eye-spot hover fly ( Eristalinus sepulchralis )

The eristalinus aeneus ( Eristalinus aeneus) is a fly from the family of hoverflies (Syrphidae).

features

The flies reach a size of 8 to 11 mm. From a distance, the dark and shiny metallic species looks a bit dusty on the head. On closer inspection, one can see the dotted and colliding eyes. The antennae are dull brown and the forehead is lightly dusted. A dark central welt can be seen on the hairy, light face. The mesonotum , shields and the abdomen are bronze-colored, metallic, shiny and lightly haired. In southern Europe, especially female animals often have five gray longitudinal lines on the mesonotum. The legs are black, the knees yellow. The rail has a gradient from yellow to black. The wings have slightly brownish veins. The species can be confused with the black eye-spot hover fly ( Eristalinus sepulchralis ), which is not as shiny, has slightly wider separate eyes and is smaller.

Occurrence

The glossy silt hover fly is common in Europe, North and Central Asia, Africa and North America. In Central Europe they are mostly found near fresh water, coastal lagoons, ponds, slow rivers, streams and irrigation ditches, but also inland but also away from the water. It flies from April to September.

Way of life

The Imagines fly very fast and low over ground vegetation, rocks and plants. They are flower visitors on daisies , ground elder , coltsfoot and wild carrot . The adults overwinter in southern Europe. The larvae live as rat-tail larvae in muddy waters, silt, fresh water seepage and in the unclean rock pools on the sea coast, inland also in animal manure such as that of pigs and sewage treatment plants.

Taxonomy and systematics

The shiny rotten mud fly was described by Scopoli in 1763 under the name Conops aeneus and placed in the genus Eristalis by Latreille in 1804 . Meigen delimited this genus in 1822 according to morphological aspects, especially according to the veining of the wings. In 1845 Rondani put together the Palearctic species, including the shiny silted mud flies, in the subgenus Eristalinus . In 1897 two genera, namely Eristalodes and Lathyrophthalmus, were separated from the genus Eristalis by Mik, and the shiny mud flies came under the genus Lathyrophthalmus . The subgenus Eristalinus with a few remaining species was also mostly viewed as a separate genus. The directories in the late 20th century as the Catalog of the Diptera of the African Tropical Region of Smith and Vockeroth, 1980, and the Manual of Palaearctic Diptera Thompson and Rotheray, 1998, the three genera were however again as subgenera in the genus Eristalinus summarized . Therefore, the scientific name Eristalinus (Lathyrophthalmus) aeneus is currently mostly used for the shiny silt hover fly . Molecular genetic work, larval studies and the investigation of the male genital organs of the flies introduced by Kanervo in 1938 to distinguish between species could lead to a regrouping of the species complex. However, the abandonment of the concept of the three sub-genera does not entail any change in the generic and species names, especially in the case of the glossy silt hover fly.
