Glasswing Butterfly
These dainty butterflies are about half the size of the Dingy Swallowtail. The upper wing is almost transparent, with only the back markings and a light dusting of white.
They have constantly returned to the buddleia to feed during the last two days, and may have been visiting it far longer.
This was the first of their species I have seen outside books and web sites. Another exciting discovery, at least for me.
