Ormyridae, ex Antistrophus laciniatus, dorsal - Ormyrus - Female
Plymouth Rock, Winneshiek County, Iowa, USA
September 15, 2018
August 31, 2018: collected seed of Compass Plant, Silphium laciniatum, from a planted prairie
September 8, 2018: scattering the above seed on another prairie planting found these galls, put them into a jar

September 15, 2018: alas, no gall wasps, rather 3 parasitoids (NOT Eulophidae)

December 2018: double checking refrigerated rearing jars, 11 dead wasps, they must have emerged close to the September date

Ormyrus…
Gall wasp parasitoids. The remaining ten wasps in your image also appear to be in this genus.

See reference here.

Thank you.
It's hard to get to know the neighbors when there are so many of them! Another FAMILY I've never even heard of.
Two questions:
Are the individuals with stubbed rounded abdomens males?
If so, why so many males in the batch?
