The Pink-Edged Sulphur (Colias interior) is not very popular in Maryland, according to every map, website and book I have ever seen, so I can’t really say I got one here. The photo above was taken at Blackwater Wildlife Refuge.
If you didn’t know it, or couldn’t guess it, the Pink-Edged Sulphur has a distinct pink edge along its entire wing, which we have here. It also lacks any dark postmedian spots and has a single white eyespot, which kind of looks like what’s going on here, but I could argue the postmedian marks are there, just very faint.
It’s very possibly I have a Clouded Sulphur here and if I ever nab something I am sure is a Pink-Edge, I will most likely replace this shot.
