Fraxinus excelsior, Dronten © Arnold Grosscurt

parasiet

Oviposition on a terminal leaf bud; two generations, both causing leaf galls; hibernation as egg on the bark of the host plant. The larvae are dark.

host plants

Oleaceae, monophagous

Fraxinus angustifolia subsp. oxycarpa, excelsior, ornus.

In his list of Psylloidea host plants, Burckhardt (2002a) mentions F. excelsior only.

notes

P. fraxini is, at least in northwestern Europe, the commonest of a group of species that all cause identical galls on ash. For an identification of these Psyllopsis species a microscopical examination of the larvae or the male genitalia is required.
