Gallformers ID Notes
“
Oaks have occasionally been seen with an unusual density of buds. persisting on the tree through the winter. On oaks definitively identified as Quercus macrocarpa in Manitoba (2), these buds resembled normal buds except int their number and clustering. On an unidentified white-group oak in Pennsylvania, many of these buds had egress holes suggesting cynipinid wasps had inhabited them. These may not be the same species, and the Manitoba symptom may not even be a gall per se.
