There are about 450 species in the U.S.A. and about 5000 different species of ladybugs throughout the world.
This, the seven-spotted lady beetle, is one of the two most common Ladybugs that were introduced in the 1970's in the USA.
Very beneficial to the garden, munching on aphids. Extra ladybugs for your garden can be purchased.

You can purchase them but there's no guarantee they'll stay in your yard. I love to watch the ladybug lovefest every spring on my old silver maple - they tend to like the new growth. Must be where the aphids are. But for about three weeks the lower branches of the maple are covered in ladybugs - it's fascinating to watch them mate and go about their lives!
