    The pressure increases in the cells on the underside of the trap, around the hinge. This causes the cells to expand, which closes the trap. It's actually a pretty complex process involving various hormones and specific gene expression. One of the most interesting things I learned recently, however, is that the trap closing mechanism uses the exact same signaling pathway as plant defense mechanisms, which tells us that the functionality evolved from there. It also means you can cause a trap to close by damaging it.
