Classification:
Helophilus trivittatus belongs to the subfamily Eristalinae, tribe Eristalini.
Distribution:
From Fennoscandia south to the Mediterranean and from Ireland eastwards through Eurasia to the Pacific, including Iran and Afghanistan.
Habitat:
Various preferably open and humid habitats; river margins, seasonal flooded grassland, salt marshes and irrigation ditches in farmland.
Description:
Helophilus trivittatus has a body length of 12 - 18 mm. The eyes are bald. The face has a wide, bare yellow median strip. The antennae are black, the third antenna segment is longer than it is wide.
Helophilus trivittatus differs from the other Helophilus species in Germany in the color of the median strip on the face which is black in the other species.
Biology:
Helophilus trivittatus flies in two generations from April to October. The species belongs to the migrants. Not infrequently, imagines can be found at greater distances from sites suitable for larval development. Adults fly fast and low in the ground vegetation, usually near slow flowing water. They visit the flowers of a variety of different plants, here for example Cirsium and Canada goldenrod (Solidago canadensis).
The larvae develop in water with a high content of organic matter, such as animal faeces and rotting plants. Helophilus trivittatus overwinters as a larva. The pupal stage lasts about 2 weeks.
