Stick Insect, Phasmid

A Phasmid with its front left leg regenerating.
Unlike popular belief that Phasmid can regrow their limbs immediately, that is not true. They can regrow lost limbs in their next molt but may not necessarily regrow it completely right away as shown in the pictures.
The front left leg is wiry and curled, probably just regrown from the latest molt. It will get longer in the next molt and might get to the same length as the front leg, but sometimes it does not but useable.
They will not regrow lost limbs once they are adult and do not molt anymore.
