Re: Informal survey: ladybug oddities?

Hello Kathy!
We have these ladybugs in plenty, or something
very like them, in Georgia. I thought I had heard
they were introduced, originally into FL, to control
aphids in pecan groves; though that makes sense if
they go after them on hardwoods generally. I
understand they are since spreading north and becoming
more abundant. They gather and look for shelter in the
fall where they spend the winter. I certainly have
found clumps of them in the cold weather in sheds,
woodpiles and other sheltered spots, so I guess they
could get into a not-well-sealed cabin or house. And
they do bite at the least disturbance.
