gal: De gal onderscheidt zich van die van Aceria galiobia (die ook in de bloeiwijze voorkomt) doordat de bloemknop sterk vergroot is, maar toch als zodanig herkenbaar blijft. Eén tot drie oranje larven per gal. Binnenzijde van de gal bekleed met mycelium waarmee de larve zich voedt. Er zijn twee generaries per jaar. Skuhravá, Skuhravý & Jørgensen (2006a) schrijven dat volgroeide larven de gal verlaten en zich in de grond verpoppen, maar Redfern & Shirley (2011a) stellen dat ook poppen de gal kunnen worden aangetroffen.

gall: The gall is distinguished from the one of Aceria galiobia (that also may occur in the inflorescence) by the fact that the flower bud is strongly enlarged, but nevertheless remains recognisable as such. One to three orange larvae share a gall. Inside of the gall lined with nutritive mycelium. There are two generations per year. Skuhravá, Skuhravý & Jørgensen (2006a) write that full-grown larvae leave the gall to pupate in the ground, but Redfern & Shirley (2011a) maintain that also pupae may be found in the galls.
