General: Hover Flies (Family Syrphidae), also called Flower Flies and Syrphid Flies, are a diverse group of flies that have color patterns that match, or mimic, wasps and bees. These flies are often seen hovering in mid air or hovering over flowers. Adults feed on nectar, and many species have larvae that eat aphids. As such, they are important pollinators and important natural control for harmful aphids.
