she had dumps like a trunk

I found a ladybug on my window sill today.  I have heard rumors that ladybugs tend to be considered lucky if they're found in your house, so I'm gonna take it.  I associate ladybugs with spring or summer really, so, what are the odds of finding one in my bedroom in the beginning of February?

Totally going to take this as a sign of luck, thankyouverymuch.
