Hmmnn... it wasn't as many as in the picture, but there seemed to be a certain season for them. If you walked outside for five minutes, you always had to make sure to brush away roughly twenty of them from your clothes. I used to live in Tennessee, and 'ladybug season' usually began when summer started.
Hihi, I just looked up the Harlequin ladybird, and I'm pretty sure that was it! I looked up 'yellow ladybird', but their heads were always yellow with spots. The ones I saw had black heads and white eyespots. The number of spots seemed to be correct though. Thx!
