Hover-flies apparently like doing what
they are named after: hovering. When hovering, they can change their
direction, go backward or shoot forward all of a sudden.
Hovering is what the males do when they display. They approach a female that sits in a blossom, make themselves heard by their humming, go a little here and there and finally remain hovering above her. If the female does not demonstratingly take off, she thinks that he has gotten everything a good hover-fly needs to have and accepts him as the father of her offspring. The wedding often takes place in the blossom. The species in the picture is named Eristalis horticola. |
