About this time each year, our home is visited (invaded) by legions of Ladybugs. They gravitate to the top corners of our highest ceilings where they huddlle together for the winter in a state of diapause. As day length in spring increases, they are among the first insects to return to the gardens where they provide a very helpful function by feeding on aphids and spider mites. Coccinellids are found worldwide, with over 5,000 species of which more than 450 are native to North America alone. I have a live and let live policy with respect to Ladybugs. Our cleaning ladies take a different view.
