Lignyodes bischoffi Blatchley, 1916
Fraxinus pennsylvanica fruits with oviposition scars (from Wanat & Mocarski)
a solitary larve develops in the fruit, completely devouring its contents. The oviposition scar, generally in the basal, thickest part of the fruit, turns intensely purple, which enables to recognise attacked fruits until late autumn. The host plant, like the weevil originally north American, is regularly planted in eastern Europe.
Fraxinus americana, pennsylvanica.
Rarely, and in small numbers also Fraxinus angustifolia subsp. oxycarpa, excelsior, ornus.
