Plant Parasites of Europe

leafminers, galls and fungi

Psyllopsis repens

Psyllopsis repens Loginova, 1963

on Fraxinus


Like all species of the genus, this species has two generations. The larvae of the first generation make leaf roll galls that are indistinguishable from those of the other Psyllopsis species (see P. fraxini as an example). However, the larvae of the second generation cause a galling of terminal buds in late summer. Three or four larvae sit each under a bud scale, hidden by a dense mass of was threads, while the entire bud is transformed into an orderless mass of scales, pointing in all directions.


Oleaceae, monophagous

Fraxinus angustifolia subsp. oxycarpa + syriaca, excelsior, ornus.


The species has been described from the Caucasus, but has been found recently in Serbia.
