Some are born without hind legs. They are also known to eat their own legs to avoid starvation when food isn't plentiful.
They lose their tails, not legs.
It is called a leg=)
From my expirience with crickets (growing up with 2 brothers and playing with inocent little insects) they live about 5 minutes after the hind legs are removed. i highly recommend not conducting an expiriment to prove me right or wrong; can you imagine how painful that must be? But it also depends on the size of the cricket. the smaller ones die sooner than the larger ones, and the larger ones try to escape with their front legs. answering this question brings back memories....

Simple answer: you can't. Spot training is a myth. To lose fat on your legs, you must lose it all over - this is achieved by a healthy diet and exercise (both cardio AND weight training), and there is nothing "short" about the time it takes to do this. If you are female, your legs will likely be the last place you lose fat from.
