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 and due to its long snout it can forage on tubulous flowers. Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle.
