Gallformers ID Notes
“
Large, irregularly globular vein pockets on the lower side of Quercus marilandica leaves, leaving a narrowly pinched linear opening above. These galls resemble those of Dryocosmus quercuspalustris in their thin, succulent, green walls, with the same pubescence as the leaf, but contain loose cecidomyiid larvae rather than a free-rolling cynipid cell, and externally are of a more irregularly globular shape. It is similar in phenology and form to the early Macrodiplosis galls found on some other eastern red oaks but seems to be considerably larger and more globular. Tentatively placed in Macrodiplosis based on the host genus and gall affinity.
Observed in Texas in April (2)
