This is not the most common of the Hairstreak Butterflies, but I have seen it 3 other times before these two in my garden the other day. These photos of two different individuals show the variations in shades of green they can have. And yes, there are other species of green hairstreaks that are different in design from this one and their IDs are also not based on the shade of green which seems to vary in all the green ones.
See my Tropical Greenstreak, Cyanophrys herodotus Gallery for more photos and more shades of green! 🙂
¡Pura Vida!
