The Aculeate Hymenoptera in particular. This excepts the massive Ichneumon group, the Gall wasps and the Chalcids. The possibilities for photos are massive. Though these are fast and wary beasts even when they are nectaring on flowers sometimes. The possibility of identifiable species in photos is difficult at this time. I will attempt to add some more social wasp shots this year. And more of the flower bee species. See the first thumb for further info on this digging Ammophila. Also keys for the Sphecid wasp genera are linked through the main Sphecid key here.
