Identification difficulty
Recording advice

Habitat

Associated with Prunus species (all year) and reeds (especially Common Reed (Phragmites australis) in the summer.

When to see it

April to September.

Life History

The eggs of Hyalopterus pruni overwinter on Prunus species. They hatch in April. The population of Hyalopterus on plum continues to increase through June and July, and many aphids may remain on plum all year rather than migrating to the secondary host. Others move to the summer host (reeds) and on this host the species exhibits colour polymorphism, with two colour forms - green and dark red.
