Moths will attach an egg to the bean, and the larva will eat its way inside and ingest the inside. If the temperature outside increases, the larva will begin jumping in an attempt to roll the bean (though not technically a “bean”) to a cooler area.
Interestingly, it can survive for months in the bean but will only live a few days once it leaves (as a pupa).

Mice and rodents squeak, and prairie dogs (which are rodents) have an extremely highly developed language that produce a large spectrum of different types of squeaks (which can be very endearing). Therefore, I was suddenly curious what a squeak of a capybara, the largest type of rodent, sounds like.
It’s actually closer to that of a guinea pig. It produces a continuous sound output.
