[QUOTE=dsmalex97;92032]Remove back legs? I have never heard of that, sounds kind of weird.QUOTE]

What I call "back legs" are the legs which help the locust to jump.
If you touch them, you can see that they can cut a little bit, and then, can damage the internal mouth of the frogs.

Also, if the locust can't jump anymore, it is easier for the frog to catch it
