Syrphid fly adults resemble bees but have only one pair of wings and much shorter antennae. They can be seen hovering in the air near plants. Their larvae are predators.
Syrphid fly larvae are usually light green, legless maggots, rounded at the rear and tapering to a point at the head. When the maggot is crawling, the head moves from side to side .
The larvae eat aphids and other soft-bodied insects.
Tachinid fly adults are hairy and bristly. Their larvae feed on moth, beetle, and stinkbug larvae.
Robber flies are general predators that eat aphids, moths, beetles, and many other pests.
