They belong in the Brachycera suborder. Most hoverflies are mimetic – they have a mimicry. They are similar to Aculeata (bees, wasps, and bumblebees). They can often be seen with bees and wasps on flowers. Their body is also striped, just like that of bees and wasps. They imitate Hymenoptera, who have a poisonous sting, to protect themselves from insect-eating enemies, but they do not have a poisonous sting. They have extraordinarily large eyes and when they fly, a loud buzz can be heard. They are excellent at flying: in addition to regular flying, they can also stay put in air and, to an extent, fly backwards.
