While repotting my G. hispidula today, I decided to disect a trap.
For those not familiar with genlesia trapping mechanisms, here is a pic of one of the underground stolons. The tiny bugs who find themselves in anaerobic conditions make their way up the corkscrews in search of oxygen. Then they go up the tube and are trapped in the bulb (out of focus but I circled it.)
I disected the bulb, and here is the inside. The little brown things that look like nepenthes seeds are the prey.
And here is the tube in between the bulb and the corkscrews.
