This is a great series! If we can figure out what the plant was, we might be able to give you a species on the wasp.

Eutomostethus??? not sure

i will look into the plant, or take a picture of it. thanks Eric.

Plant appears to be Cleavers (Galium aparine), a sprawling, prickly species of bedstraw found mainly in forest habitats. This is the one that commonly wraps itself around your ankles as you walk through the woods.
