Several galls were collected from the vicinity of the University of East Anglia NR4 7TJ in November 2021 and pinned for a collection. On recovering the sealed display box from my university over a year later, I found several small parasitic wasps in the corner, including this one which does not appear to be a gall wasp.
The wasp is just under 2 mm long. The galls in the collection it was found in are members of the following genera: Andricus, Biorhiza, Cynips and Neuroterus.

If it is Ormyridae, will be an Ormyrus sp. as this is only genus of this family in Britain as far as I am aware.
