Do bugs sleep? Do they have rest periods where they recharge?

Yes they do. It's a little different than our sleep, but they do. Our understanding of circadian clocks actually come from fruit fly research primarily. Also, many groups (like most moths, etc) are nocturnal, implying they have rest periods during the day, etc. The sleep is not as strong as ours, they are easily woken up and react.

Edit: just to add a distinction, there is a difference between sleep and overwintering in insects. During overwintering, insects slow their metabolism and can produce glycerol to protect themselves from freezing conditions. If you've seen an insect look very still during the winter, it's most likely in an overwintering state and not truly sleeping.
