Smooth Spangle Gall

Smooth Spangle Gall

Observation - Smooth Spangle Gall. Description: Shown near common spangle gall on oak leaf. Should insect-caused galls be in invertebrates or plants? The system puts them in invertebrates for the causer rather than the host, but I feel botanists might be better at recognising them?
