Cola-nut galls
The physical appearance of the galls
The galls are found in small groups, which however do not coalesce, helping to prevent mis-identification with the
Distribution
It is well known in continental Europe, occurring from Great Britain to Asia Minor.
Life-cycle
The imago of the agamic phase emerges in early summer following the gall's inception. The bisexual generation gall is very similar to that of A. kollari, effecting the live bud of Quercus species[2] and has only been seen under culture conditions (1975).[3] Removing and destroying cola-nut galls before they dry and the wasps emerge may help to reduce an infestation. While fairly large, and sometimes present in quite large numbers on scrub specimens, they cause no measurable harm.
