I have probably about a hundred ladybugs on 2 separate walls outside. I have never seen this many ladybugs before in my life. I have heard from superstition that if a ladybug lands on you it will bring you good luck(boy could I use that lol). I know that they won't bite you, but there is also another bug that is close to them everywhere also. It is about 1/8" long, and they are not bothering me either. They have the same color makings as the ladybug, but their bodies are mainly black with orange king of stripe on their back. What draws this many ladybugs to my wall?
