Small Tortoiseshell in Falmouth today - probably not that unexpected, although numbers last year seemed up, which was a good thing.
(Dreamed of a Red Admiral 2 or 3 nights ago, although that obviously doesn't count)
Two Speckled Woods chasing each other in garden yesterday (Devon).
That seems pretty early- especially as the weather's been quite chilly recently. Sometimes see my first by end of March, but usually April.
Brimstone in coppiced woodland this morning was my first butterfly of the year!
