Treecreeper and the first butterfly

Is this a record - there was a butterfly flitting around inside the Christian Centre during the service last Sunday 24 Jan 2010? woken up by the warmth, I guess, it did not stop long enough to see what it was, probably a tortoiseshell.
And in the garden just now there is a treecreeper on our birch tree - well named, as it does creep up the trunk pecking away looking for insects in the bark.
