Yup, my boyfriend has pet grasshoppers every summer. He caught a gimpy one that only had one leg and it does fine.
As long as they are in captivity they have a lesser chance of getting eaten by a bird.
why do you want to know?
yes i've seen one with no legs, still alive... i put it out of its misery... i'm sorry... it looked pitiful...
they can survive but loosing a leg will slow anyone or thing down. Poor creature.
Yes, insects can survive without legs, however then they will have little to no way to get food and eventually starve to death.
