Symmorphus crassicornis ♀︎

2021-VII-03

The nestblock I’ve installed specifically for Ancistrocerus and Symmorphus wasps, see here, has not shown results so far. This female Symmorphus crassicornis [1] has been the only visitor so far but she has not returned. On the other hand the block is full with bee and digger wasp nests.
