The black eye-spot-hover-fly or spotted- eye-hover -fly or mat rotten mud -hover-fly ( Eristalinus sepulchralis ) is a fly from the family of the hover- flies (Syrphidae).
features
The flies reach a body length of 7 to 9 millimeters (males) or 9 to 11 millimeters (females). Her body is small and stocky, the strong head is covered with hair. The compound eyes have a light brownish-yellow base color and are dark marbled. The two eyes are also separate in the males. The antennae are brown, the third link is slightly lighter on the underside. The face is colored white-gray and has shiny black bumps. The mesonotum is black in color and has three indistinct, light vertical stripes in the male, which are easily recognizable in the female, which converge at the back. The legs are black, occasionally the knees and the base of each tarsal link are reddish brown. The thighs and rails of the hind legs are clearly curved. The wings are transparent and have a black point on the edge. They lack the spurious vein ( vena spuria ) typical of hoverflies . The abdomen is oval and tapered backwards. That of the males is velvety black, is shiny on the rear edges of the front tergites and has shiny round spots on these tergites. The tergites of the fourth and fifth abdomen segments are glossy. The females have a completely shiny abdomen. The species can be confused with Eristalinus aeneus , which, however, has a shiny abdomen in both sexes.
Occurrence and way of life
The species occurs from West Africa across the entire Palearctic to the Oriental . It flies from April to September. The adults can be found on flowers, the larvae develop in muddy waters and in silt , which is also referred to by the German name Matte Faulschlammschwebfliege.
