Rhingia campestris is a species of hoverfly, Script error: No such module "convert". long, with a wingspan of Script error: No such module "convert".. It is common across the Palearctic from March until November. It has a broad orange abdomen with a black line along the sides (the black line is absent along the sides of Rhingia rostrata), and has the distinctive long snout of all Rhingia species. Rhingia campestris is the main pollinator for many plant species[1] and due to its long snout it can forage on tubulous flowers. Larvae are associated with cow dung. Adults males feed on nectar, while adult females feed on protein rich pollen, reflecting the cost of developing eggs.
