Syrphid Fly

Syrphid Fly - Toxomerus marginatus

These are some of the smallest (3/16" or so) of a group of flies often called Hover Flies. They feed on nectar and pollen and, with their black and yellow markings, seek to mimic bees or wasps. However, syrphid flies cannot sting.



Syrphid flies are generally consider beneficial because the adults are pollinators and their larvae are voracious consumers of aphids, thrips and small caterpillars.
