I was on my way outside to fill up the bird feeder yesterday when I discovered this beautiful Speckled Wood sitting quite happily on the windowframe - inside the building. It seemed a bit late in the year (though there are still butterflies on the wing outside at the moment) so I consulted Ian Dawson, insect guru, and he came to have a look.
We were puzzling over what the butterfly was doing indoors when he found its chrysalis stuck to the doorframe:
He told me that Speckled Woods are the only British butterflies which can overwinter in caterpillar or chrysalis forms, but not adult... They only last for five days anyway.
