Atylotus rusticus
Atylotus rusticus is a species of horse-flies in the genus Atylotus. It is found in Europe, Asia and North Africa.
Atylotus rusticus belongs to the group of insects known as Holometabola, which go through metamorphosis during their life. The larvae are radically different from the full-grown insects. Between the larval stage and the grown stage is a pupal stage, where the fly's inner and outer organs develop.
