Multicolored Asian Lady Beetle Pupa

This is the pupa of a Lady Beetle (AKA Ladybug) and normally that would be a good thing as they are important predators that help to control Aphids.  This however is the Pupa of an Invasive Exotic, Multicolored Asian Lady Beetle, a species that is most likely displacing native species as it is so aggressive.  Here is a BugGuide image.   Larvae will prey on other Lady Beetle larvae.  Multicolored Asian Lady Beetles are reported to invade homes in large numbers to hibernate.

A Facebook Comment from Kiki Gee:
The Asian lady beetle has decimated our indigenous 9 spotted lady beetle. If you ever find one dead or alive, Dr. John Losey at Cornell University would like to know. I worked with him, and he has an ongoing study trying to increase their population.
