Beautiful Brimstone.

Yesterday was another glorious day,after sorting out the Sycamore posts for my rustic fence near the dyke, I sat and watched the birds for a little while, a male and female Blackcap came visiting, flitting in the Forsythia, heard a Willow warbler in the woods at the back of the dyke.and at last two Blue tits have decided which nesting box they like ,and are now building a nest.
Also a Brimstone butterfly was in the garden.
