First butterfly of the year

On Thursday 25th March at 12 noon at the start of my lunchbreak, I went to the SE corner of the James Paget Hospital, I was out looking for the WTE needless to say I didn't see it so 13th one missed in Lizard Land, but I did see a fine Peacock butterfly and settle at he back of a bus so I could ID it. A Sparrowhawk was circling over (No bins with me so I couldn't say whether male or female).
