I have two of these little guys in my bug collection (pinned) they are quite small, so I've glued them to tiny paper triangles. Are you sure that these ones are not glued to the paper? I can't see any pins.
Ah I see, Kudos to whoever did the pinning as well then.I'm sure they are glued. I should have said: Kudos to who ever set and preserved these.
I was using pinned as a generic term for preserving invertebrates.
