An amazing acrobat

Hover flies are capable of astounding flying feats.

When wings are present in insects, they commonly consist of two pairs. These include grasshoppers, bees, wasps, dragonflies, true bugs, butterflies, moths and others. But true flies are a large group of insects with only one pair of wings, although they have small balancing organs known as halteres where a second pair of wings might develop. The halteres vibrate with the wings and sense changes of direction.

Flies, like hover flies for example, are capable of astounding feats, including moving forward, backward, sideways, and up and down. They can truly hover also, which is an uncommon ability in insects.
