Here's some traps of different utrics that I have. If the names are reasonably certain I have them listed if I don't know it's called unknown and numbered. I'll try and get the rest tomorrow.
U. praelonga the coolest traps they all seem to have the blue circles on the trap
U. alpina or U. longifolia?
U. livida another awesome trap with wide wings at the entrance
U. nanna either this plant does not produce larger traps or they are all as few and far between and minute as this. The little crustacean I found on the stolon (not thinking I didn't take a shot of that) was easier to spot than this bladder, or the start of one
