Doesn’t the idea of tent-making bats sound fun? I feel like they’d be excellent camping partners, because if you were ever stuck without shelter they could just whip up a tent for everyone to sleep in. Actual tent-making bats really do make tents, but they certainly aren’t large enough for people to stay in. Still, it’s a pretty cool way to build a roost.

Tent-making bats are found in Central and South America, from Mexico to Peru and Brazil. They live in forests, usually at elevations below 600 m. These bats mainly eat fruit, so they need to live in places where there are enough fruits to sustain them.

Tent-making bats are kind of cute, in a batty kind of way. They are not very large, growing to lengths of 5.9-6.9 cm. Their faces are decorated with a modest noseleaf, as well as four distinct white stripes. Each bat also has a white stripe that runs along the back to the base of the tail. The rest of their fur is grey-brown.

These bats are known for their roosting behaviour, which of course involves constructing tents. They do this by chewing at special spots along the middle of large leaves, so that they fold and create a tent-like structure. Tent-making bats usually choose banana or palm leaves for their roosts, and pick trees that are tall, but not overly so. It’s thought that this is because tall trees are better protected against predators, but that very tall trees are more exposed to weather.

The downside about this tent-making process is that it takes a few nights, and the bats have to build a new one every couple of months, as the leaves dry out and fall off. Luckily the bats have friends to share in the work, as up to 59 bats will share a single roost.

Tent-making bats breed twice a year, in February and June. This is when plants are fruiting and flowering, which provides food for the pregnant bats and their young. The bats give birth to only one pup after four to five months. The babies are kept in communal roosts, and are independent a month after birth.

Although leaf homes might not seem like the greatest of shelters, this system seems to work pretty well for the tent-making bats. They are currently doing very well in their range, and hopefully will continue to do so.
