First there are billions of insects and billions of individuals will not survive winter.

Different species adopt different strategies to get through. Some rely on their eggs to carry the species on; they lay them in sheltered places: under tree bark, leaf litter, underground. Some attempt to find sheltered places to hibernate. Some allow their entire population to die off leaving only the fertile queen to make it to Spring.
