Still in Ohio, gall of the week is a leaf gall on white swamp oak, Quercus bicolor. Seems to be Neuroterus quercusverrucarum, the oak flake gall. Is this correct @gallformers?

Yes it does (and not only the hybrid), in fact three species of the aphid genus Pemphigus occur on the petioles of P. nigra and its hybrids’

Gall of the week: Galling is in Ohio USA, and came across this. Seems to be a rough oak bulletgall caused by the cynipid wasp Disholcaspis quercusmamma on swamp white oak, Quercus bicolor. Happy to be corrected.

Gall of the week is a bit of a mystery. It occurs on tree-fuschia, Halleria lucida, in South Africa, I suspect it is caused by a cynipid wasp, Halleriaphagus phagolucida, but does anyone know different?

Have been catching up with verifying cynipid galls on iNaturalist. The process can be greatly speeded up if you can remember to add the generation to the name. For example Biorhiza pallida f. sexual for the oak apple gall causer, and Andricus aries f. agamic for the ramshorn gall causers.

These are knopper galls caused by the cynipid wasp Andricus quercuscalicis f. agamic.

Gall of the week is a fungal gall which at first sight might be taken for an invertebrate gall, although the there is a larger protuberance on the underside of the leaf. It is caused by Exobasidium vaccinii on cowberry, Vaccinium vitis-idaea.
