How does an aye-aye get insects?

It uses its skinny middle finger to tap on trees, while listening with its bat-like ears. This acts as a form of echolocation, allowing the aye-aye to detect hollow spaces in the wood in which insects are hiding. The aye-aye then uses its rodent-like front teeth (which never stop growing) to gnaw open a whole in the wood. Finally, they fish around in the hole with their middle finger and drag out any insects for consumption.
