Multicolored Asian Lady Beetle

I like this site for IDing Ladybird beetles. http://www.discoverlife.org/20/q?guide=Ladybug I'm fairly sure yours is the MULTICOLORED ASIAN LADY BEETLE, Harmonia axyridis. http://www.discoverlife.org/20/q?guide=Ladybug

There are several different species of lady bug... can't tell for sure which one yours is but here are some pictures. http://www.google.com/images?q=ladybug&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&source=univ&sa=X&ei=uYN3TZ6vFoLG0QHO8IjiBg&ved=0CDoQsAQ&biw=1365&bih=813 They are very beneficial since they eat aphids. Aphids can be very destructive to food crops (fruit trees especially)
