Life Cycle

 Adults average about 3/8 of an inch in length and about 1/4-inch in width. The common name "multicolored Asian lady beetle" refers to the fact that individuals are extremely variable in appearance.

 Since the elytra (modified forewings of beetles) can look similar to those of several native species, perhaps the best identifying feature is the thorax (body segment behind the head). The thorax is mostly white with a large black marking that looks like an "M". The larvae are difficult to tell from those of most other ladybugs and are mostly black with orange spines on their back.

 When handled, adults secrete a foul smelling and slightly toxic liquid from their legs.  They are also capable of inflicting a painful bite.
