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.
