The kind of ladybugs you usually find in your house are multi-colored Asian ladybugs. In Asia, these ladybugs survive winter by living in the crevices of limestone cliffs or in cracks around buildings. They like to hibernate in groups, and future generations will come back year after year. The best offense is a good defense, and weasels specialize in both. They are excellent hunters and are also good at defending themselves against predators.
Weasels also have another line of defense camouflage.
They shed their fur twice a year. In spring, they shed their winter coat and become mostly brown. During fall, weasels trade their brown summer coat for a white one that blends into the snowy winter landscape. Camouflaged, weasels can elude predators and catch prey.
