Hello bug lovers! In this exciting edition of Arthro-Pod, Jody leads Mike and Jon through an episode entirely dedicated to the multicolored Asian lady beetle. It is known by many names, the multicolored lady bug, the Halloween beetle, and the fake ladybug amongst others. You may have seen them in your home just recently or been unlucky enough to feel their bite! In this episode, you'll learn how they appeared in the US, the other ways they can pose problems, and ponder the reasons why people would call a real member of the Coccinelidae a "fake lady beetle".
