Pain sensors are different things from temperature sensors, to my
knowledge. As far as I was aware, the sensors that tell you that you've cut
your finger are different from those that tell you you're touching
something hot. Insects don't have the former type of sensor, but they DO
have the second type, so if you burn or freeze an insect, they can
presumably feel it. If this seems hard to conceive of, I think there is
something of an analogy in leprosy, where people retain the ability to feel
things, but their pain sensors are dead, so they can't distinguish a
harmless contact from an injury. I also think they can still feel hot and
cold. If I'm wrong on any of these points, I'd be happy to learn otherwise.
