Gallformers ID Notes
“
Small clumps of white/yellow fuzz, fading to tan or brown, in pinched areas of the leaf lamina, along the midrib, down the petiole and onto stems of new growth on Notholithocarpus densiflorus. Sometimes coalesced clusters became larger swellings.
"Dasineura" is a very tentative ID, based on the fact that larvae extracted from leaf midrib galls matched descriptions of Dasineura in Gagne (1989). The taxon responsible for this gall is not known. It also remains to be determined whether the fuzzy midge gall found on tanoak flowers is caused by the same midge.
