If you can't tell from my bad photography, it is a ladybug. If it was the first ladybug it would not be so surprising based on the variety of bugs I have seen this week. This is one of many I have seen in the past three months. It's almost like the insects and the arachnids had a meeting and said, "Yea, we heard the ladybugs say it was a good place to winter, but, if you try it, you are on you own." Hands down, I have seen more ladybugs than anything else.
If it's a "good" bug can it still be called an infestation?
