Asian lady beetle
The multicolored Asian lady beetle, Harmonia axyridis was introduced to the US some years ago as a deterrent to aphids. Described as multicolored, most of what I see are the famous Auburn orange. Our native lady bugs are UGA and U AL red and black.
Will Auburn University ever learn? (I did not find a confession on any Auburn site, they just mention that the bugs 'were introduced' but I had it on good authority from my son who graduated from Georgia Tech that Auburn scientists were the guilty parties. Ohio State does not point any fingers, but are careful to say that while Asian lady beetles were released in Ohio, it was not done by their university scientists.
There is controversy over whether these critters bite? I have a whelp on my neck that I am sure was caused by an Asian lady beetle because I brushed him off and saw the thing. They are not venomous but can cause an allergic reaction.
This is the best source I found for both history and control of Asian lady beetles:
