cream spot ladybird

on the window sill in the bathroom (no windows open!) while i was taking a shower. how did it get there?

once again i have great respect for wildlife photographers who get that pin-sharp shot - did you know ladybirbs can move really quite fast?!!!!

ps i tried to remove the little peice of thread on its back, but, as the ladybird was only 3-4mm in length, i don't think i succeeded!
