wasps emerged from spiny rose stem galls - Diplolepis spinosa
Ackworth, Warren County, Iowa, USA April 15, 2010 Size: 4 mm long
The wasps emerged! I've kept two galls in a clear plastic bottle in my garage and have been checking them daily. This morning (April 15) I noticed over a dozen small black wasps moving about inside the bottle. I quickly snapped this photo of two individuals through the plastic bottle before I headed out to work, but will get better photos later. Wasps are black-bodied (4 mm long) with reddish-brown legs and long antennae. Ventral view.
I know the caution that these might be parasitoids instead of the gallmaker, hopefully Miles Zhang or other experts can comment.
