Banksia galls

Description:

Banksia integrifolia is a tough plant. The galls are appearing on a hard inflorescence in pic 1 and 2. Soft surface but firm. The inflorescence is about 200mm tall. The flower galls are about 25mm diam. and firm but furry. The third picture shows what is very likely to be a flower-like stem gall on the same plant and is about 40mm wide.

Habitat:

Nature reserve within inner suburbia.

Notes:

Yet to research this. Galls on Eucalyptus is a poorly documented subject and I expect galls on banksia to be even less well covered. My first guess for these would be wasps. http://en.wikipedia.org/wiki/Banksia_int...

Jamie Davies says Animalia: Arthropoda: Arachnida: Trombidiformes: Eriophyidae: ...possibly a species of Aceria
