You don't expect to see a moth in November, but these winter moths have adapted to thrive in the cold. The operophtera bruceata, or the Bruce Spanworm moth, spends the summer as a catapiller in the canopy of hardwood trees. They eat and eat, getting bigger until they fall down into the leaf litter and pupate. As the weather turns cold, around the end of October, they emerge as adults. This comes in very handy for these moths, because most of the birds have migrated away and there are very few predators left.
