The ladybug and the Asian beetle look very much alike but there are some differences.
Ladybugs have a red color and a black head. The Asian beetles are more orangish red and have a white face.
If your home has been invaded by what you think could be a ladybugs chances are its actually the Asian beetles.
These beetles will bury inside of the roof of a dogs mouth. There was an article posted in December in the Houston Chronicle about this. I will enclose the link.
I took these pictures on Wednesday with my macro lens so they are still hanging around.
Look for the white head then you will know it is them. Some people say these beetles bite so beware.
Never let your eyes fool you what you think is a cute ladybug might be the evil twin in disguise.
