How do some fruit bats make shelters from leaves?

Certain species of fruit-eating bats, such as the tent-making bat (Uroderma bilobatum) and various members of the genus Artibeus, create shelters by modifying large leaves.12

To construct these roosts, the bats bite across the veins of palm or other plant leaves. This action causes the sides or ends of the leaf to collapse and hang downward, forming a protective, tent-like structure. The bats then roost on the underside of these modified leaves, which provides them with shelter.12
