Larva(e) |
Syrphid larvae [Allograpta oblique (Say) and others]: Syrphid larvae are greenish or brownish maggots that are predators of aphids. The larva has an indistinct tapering head with mouth hooks on the anterior end. A pair of dorsal tracheal trunks, visible through the thin skin, make this maggot appear to have two longitudinal stripes along its back. Larvae feed on aphids by sucking out their body fluids. Depending on the species, a larva can consume 100-900 aphids during its lifetime. The brown pupal case is tear-drop shaped with a prominent tube at the posterior end. The adult flies are brightly colored, wasp-like insects with bands across their abdomen. They are often seen hovering over plants. Syrphid flies have one pair of wings, while wasps have two pairs. |
