Can insects, crabs, spiders, and other animals with an exoskeleton become overweight or obese?

If so, how does it work? Do they just molt into larger skeletons?

I remember learning about an experiment in college where an animal with an exoskeleton (a mantis or roach maybe?) has neurons disabled that allowed it to essentially feel the pressure inside its body to tell if it should eat more or not. They continued to eat until their shells cracked open and they died. So I’m guessing there’s only a certain tolerance and they likely have a way to prevent it from happening through overeating.
