Gallformers ID Notes

A small spherical gall on the filament of the male flower of Quercus fusiformis. Green when it first appears, developing purple marks which eventually coalesce to leave only circular spots of green. This gall resembles Neuroterus quaili as well as an undescribed gall from Quercus garryana. Male and female wasps were observed on budding flowers, including some associated with this gall by oviposition bagging, suggesting that it is an agamic generation gall. The galls are thick-walled and show no evidence of a larval cell in early April when most drop from the tree.

Female wasps emerged from galls of this type over the winter following the spring they first appeared. Unpublished genetic sequencing by the Nicholls lab confirms they are conspecific with males and females that emerged from these cryptic bud galls before flowering.
