Acumyia acericola Harris, 2008
Larva and pupa in the strongly disfigured and somewhat enlarged fruit. Up to seven pupae were found in a single fruit.
Acer campestre, platanoides.
In the galls also eriophyid mites have been found, of an undefined species, and the possibility cannot be excluded that A. acericola merely is an inquiline in a mite gall.
