The case is made of two different leaves.

A caterpillar recently discovered in Peru behaves unlike any other known caterpillar. 

The critter was spotted by Dr Joe Hanson, the creator and host of the YouTube channel "It's OK to be Smart." Hanson, along with entomologist Aaron Pomerantz and guide Pedro Lima, were filming in the Peruvian Amazon when they came across the creature.

According to Hanson, this is the first known example of a caterpillar building itself a mobile shelter, which is why it has earned the name of the hermit caterpillar.
