How does the flea jump so high?

How The Flea Jumps...

A flea can jump up to 200 times its body length. That is like a human jumping 365 metres. Even Jonathan Edwards with a hop skip and a jump and a following wind only managed 18.29 metres. High speed footage has shown the flea uses it hind legs as multi-jointed levers while large spines near their feet grip the ground for extra traction.

Do insects (and other arthropods) sleep?

Insects do rest at times, aroused only by strong stimuli – the heat of day, or attack by a predator. This state is called torpor, and is the closest behavior to true sleep that bugs exhibit.
