I was finally able to confirm one of my photographs as an orange sulphur today, the latest in what I can only call an unbelievable streak of new personal sightings.
It is very difficult to tell the difference between a clouded and orange sulphur. They both land with their wings closed, hiding all the key identifiers.
For this species, there will be a little hint of orange inside the wings, whereas the clouded sulphur is more yellow. I saw the orange as it flew, but I wanted to photograph it. After many failed photo attempts because of its erratic fluttering, I got exactly what I was looking for! This is now the sixth new butterfly photographed in less than a month.
