This one has always been a little difficult for me to identify because of the same big black dot and sometimes two gray dots like Howarth’s White, but I believe now that the Giant White, Ganyra josephina (linked to my gallery) is the only White with the turquoise color on antennae and legs. Check my Howarth’s White Gallery to see how similar they are with those black and gray dots confusing me. The following 3 shots from my garden in August I believe are Giant White, based on the turquoise color.
¡Pura Vida!
