Distribution

These hoverflies are present in most of Europe, the Near East, the East Palearctic realm, the Nearctic realm, North Africa, and the Indomalayan realm. In the UK S. pyrastri is a migrant which arrives in some years in high numbers and in others is almost absent.

Larva of ''Scaeva pyrastri''

The face is yellow, with reddish brown antennae. The eyes are covered with hair. Scutellum is brown yellow. The legs are red with a black base of the femur. The male's eyes do touch in the centre of the frons, while in the females they are separated.

The larvae are light green or sometimes pink, with a white dorsal longitudinal stripe.

Habitat and behavior

This species can be found in gardens, meadows and wasteland. Adults are common visitors to flowers of Apiaceae (Umbelliferae), but also of rape, honeysuckle and daisies. They fly from April to September, with the peak in July and August. During the larval stages they may consume over 500 aphids.
