question
Please see my comments on {thumb:1436982]. Do you know if these Eurytomids are parasites of small bees? I collected several gall-like structures from goldenrods and placed them in plastic bags. The wasps started emerging from whatever about a week after I collected the structures. Both structures also had at least one dead bee hidden among the rosettes of the structure. I noticed the following on the info tab for Eurytomids --

"Food -- Some are parasitic, others phytophagous. Almost all parasitic species feed on hosts confined to galls, stems, seeds or other protected plant parts. Some are secondary parasites."

So I think this answers my question. But I'll leave my comments here. Seems these wasps are parasites of whatever was in the galls.
