Grasshoppers don't only have one leg and instead grasshoppers actually have 6 legs and they use all 6 legs for walking.
The 2 front legs are also used to hold onto food and the back too legs are extra large and made to allow the grasshopper to jump.
A grasshoppers back legs help the grasshopper jump and are also used as a defensive weapon against predators as the grasshoppers back legs can get vigorous kicks using the same process they do when they jump except when the grasshopper angles their legs at their target in defense instead of the ground.
Grasshoppers can survive without legs although once they lose their legs they cannot regrow any lost legs.
If a grasshopper loses a leg they can still survive in most cases but once the grasshopper loses a leg as an adult grasshopper it does not grow back.
Grasshoppers can go through a process of autotomy which is when a grasshopper can shed one or both hindlimbs to escape a predator or it can be abandoned or damaged.
It occurs between the grasshoppers trochanter and their femur which is the second and third leg segments and once the legs are lost on the grasshopper the legs never regenerate or grow back.
Grasshoppers cannot regenerate lost legs.
Losing the leg might have allowed it to survive an attack that might otherwise have killed it.
If a grasshopper loses an antenna or leg as a young nymph, the missing appendage is regrown, in part, at the next molt.
If the damage occurs early enough in the development of the insect, the lost appendages may be completely regenerated.
The eggs of a grasshopper are covered with a sticky substance which protects them underground, where they bind together and form an egg pod.
They'll remain in-situ for around 11 months.
The typical lifespan of a grasshopper is around 12 months.
Adult grasshoppers can live two to three months and often they die out when food becomes scarce or when the weather becomes too cold.
Many predators eat grasshoppers, including birds, blister beetles (which feed on eggs), and robber flies.
