Gallformers ID Notes

A large, hairless, irregularly globular red-orange sack gall on the lower side of leaves of an undetermined Salix species. A similar gall has been reported on Salix laevigata. Observed in Arizona in July and August.

This gall bears a resemblance to the undescribed sawfly "near Pontania pacifica" described from Salix lasiolepis in Arizona.

It is interesting to note that the two tentatively assigned hosts of this undescribed species, Salix laevigata and gooddingii, were specifically noted by Smith as "the only willows in the California area wholly found to lack" Euura/Pontania galls (page 42, second to last paragraph on left column).
