That's great! The dragonflies, being generally the larger, with the more visible characters are much easier to identify in the field. But those little guys are much more challenging. There seem to be a lot of local field guides available or coming available to help with both.
That has always been my problem though. I can't know everything, but I try anyway.
Found a couple of wasps today in the backyard, I think the first is a type of paper wasp and the 2nd a type of spider wasp. I've seen one chasing a spider before, this one was hunting along the fence and had no fear of spider webs, it just busted straight through them. Not very big, only 10 or 15mm. Never kept still so couldn't get a decent photo. Maybe in the family Pompilidae
