Among the traits of this family are a wedge-shaped body, a long and pointed pygidium (tip of the abdomen), and a helmet-shaped head.
The common name of the family Mordellidae refers to the beetle's practice of suddenly falling from a flower when alarmed. This route of escape is faster than taking the time to open the elytra and fly away.
Perhaps the most interestingly marked Tumbling Flower beetle is Hoshihananomia octopunctata, whose name is longer than the beetle itself.
