Good Deed Hoverflies

Larvae feed on many species of aphids; one larva can eat about 400 aphids during its development. They are common in orchards and are particularly strong fliers, good at finding aphid colonies, even in windy areas.


Adults are robust, shiny, yellow-and-black- or white-andblack- striped flies, 3?8 to 5?8 inch long, with large eyes. They h over over flowers like miniature hummingbirds. Hov e rflies also known as flower fliesmay resemble honeybees, but hoverflies have only one pair of wings and don’t sting. Larvae are gray or greenish, somewhat translucent, sluglike maggots up to 1?2 inch long. Eggs are tiny white cylinders laid singly or in small groups near aphids.

Getting Them on Your Side
