)

E. suffusana

A minor pest of hawthorn (
Crataegus

LIFE HISTORY
Moths fly in June and July, and are often common in
parks and gardens. Eggs laid on the foodplant hatch in
the following spring. The larvae then feed within spun
shoots during May and June; they also bore into the
young shoots. Pupation occurs in the larval habitation or
in a slight cocoon spun amongst debris on the ground.
