Although it varies by species, field and house crickets can jump about 3 feet. This is roughly equivalent to 30 times their body length.
Crickets belong to a family of insects that are characterized by their long, narrow antennae and large, sturdy hind legs. Their powerful rear appendages primarily function for leaping, which enable crickets to flee from other animals that naturally prey on them. When crickets are unable to escape, their strong back legs are also used to fend off attackers.
Aside from jumping, crickets are also excellent climbers and some species have the ability of flight. These defense mechanisms are useful in avoiding their numerous predators, which include birds, spiders, rodents and even other crickets.
