gall

oviposition scars on the petiole, generally in two rows. The later larvae, sawfly caterpillars live freely on the leaves, “hedging” the holes where they are feeding with a “palisade” of grey threads of dried saliva, that probably function as ant deterrents.

host plants

Salicaceae, monophagous

Populus nigra, tremula.

Probably not on Salix.

synonyms

Pristiphora platycerus; Cladius, Lygaeonematus, Pristiphora, Stauronematus, compressicornis auct.
