Monarch

Monarchs don't hibernate. I copied this info from the web - For some reason, monarchs have just not evolved to hibernate. The ancestors of monarchs were tropical butterflies that could not survive long periods of very cold weather. When monarchs moved into areas that had cold winters, they never evolved the ability to tolerate these winters, and need to migrate to warmer locations.Many people think that monarchs evolved in the tropics, and just move north each spring to take advantage of all the milkweed we have in the summertime. Most other temperate insects can withstand the freezing temperatures of winter by entering a state called "diapause." Some do this as eggs, others as larvae, pupae or adults.
