Are syrphid flies harmful?

Good Growing Tip of the Week: Syrphid files have sponge-like mouthparts that they use to feed on nectar, pollen, and if they land on humans, sweat. Despite what many people think, they don’t bite or sting. If you do get stung by a small insect feeding on your sweat, it is most likely a ‘true’ sweat bee.

How do you distinguish Diptera?

Do syrphid flies pollinate?

Flies are among the most frequent visitors to flowers and important pollinators of a wide range of plants.

What do syrphid flies do?

Syrphid fly adults are not predators, feeding only on pollen, nectar, and aphid honeydew. Larvae, however, are highly effective predators of green apple and spirea aphids, with each larva capable of consuming hundreds of aphids during the course of its development.

What are the flies that hover in one spot?

Why are syrphid flies beneficial?
