Garden helpers?

I was working on some summer garden clean up  to make way for the fall plants and came across some interesting critters.

Ok, I did a search and saw that the leaf bugs aren't too bad for the garden, and the Praying Mantis is good (ish) for the garden because it will eat the bad bugs (but doesn't discriminate so might eat the good guys too), but what about those other things? They are all over my eggplants
