Harmonia axyridis - Asian Multi-Colored Lady Beetle
Lady beetles are predators frequently sold for biological control, although
their effectiveness is somewhat dubious. The Asian Multi-Colored
lady beetle was intentionally released in North America as a control agent
for aphids (as seen here), but they rapidly became a pest in their own
right. The Harmonia introduction is a classic instance of
biological control gone wrong. The beetles congregate inside houses
in the winter, biting the occupants, and they have driven a number of native,
non-pesty lady beetles to local extinction.
