Some do. For example:

Hibernation as Adults. Many insects hibernate as adults. Lady bird beetles are a well-known example, and are sometimes seen in great numbers in the fall as they congregate at high elevations. Many large wasps seek shelter in the eaves and attics of houses or barns. Tree holes, leaf litter, and under logs and rocks are common shelters for overwintering adult insects. The Mourning Cloak Butterfly is usually the first butterfly that is noticed in the Spring, and this is because it hibernates in tree holes or other shelters during the winter. As in some insect larvae, it reduces the water content of its body, and builds up glycerol which acts as an antifreeze. Honey bees stay in hives during the winter, and form clusters when temperatures fall. They also are able to raise the temperature by vibrating wing muscles.
