This species usually has lots of brown spots and lines on the folded wings much like the Apricot Sulphur, but these in my garden the other day were solid yellow, or to fit their name, a bright orange! 🙂 I am pretty sure of the identification, though never certain. Here’s 3 pix from that recent sighting and for more photos, see my Orange Sulphur Gallery.
¡Pura Vida!
