Subject: Old World psyllid on western North American hawthorns

Cacopsylla peregrina (Foerster), an Old World psyllid, has been found for the first time on hawthorns in western North America. It presently occurs in British Columbia, Washington, and Oregon west of the Cascade Mountains. This psyllid is native to Europe and Asia, and could potentially survive the winters throughout eastern Canada, where hawthorns are cultivated as ornamentals.
