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.
This was one of my first “exotic” butterflies on my birthday trip to Xandari in 2019 and since I’ve seen it one other time in my garden in June of 2022 and now here in 2025. See some much better photos in my gallery:Guava Skipper.
Note that different sources have different scientific names: Phocides lilea, Phocides polybus and Phocides palemon. I still don’t know who is in charge of butterfly names, but I’m beginning to lean toward iNaturalist and put their scientific name first in my lists when more than one is used. It is not like with birds where eBird is sort of everyone’s source with confidence that it is always correct. (A least we think that!) 🙂
This Orange-barred Sulphur, Phoebis philea (my gallery link) does not have the strong “barring” that some of this species have, but the stronger yellow color to me eliminates the possibility of a a similar-spotted butterfly, the Cloudless Sulphur, which is usually white or a light yellow. But I could be wrong! 🙂 And if someone changes it on iNaturalist, I will come back and change it here! 🙂
This Blurry-striped Longtail, Chiodes catillus (my gallery link) is also sometimes called White-striped Longtail by some sources. It is a less seen longtail skipper, but one of the many species that make up the huge biodiversity of Costa Rica! Here’s two shots of the same individual showing the difference in color that bright sunlight or shadows can make on these butterflies. 🙂
One of my many “favorites” is the Tropical Buckeye, Junonia evarete or Junonia zonalis (linked to my gallery) is found throughout Central America, West Indies, Florida and the Southwestern U.S.
or at least I am pretty sure that is the identification, Banded Yellow, Eurema elathea (my gallery link) and it is common to have all of these different colors (white, tan, yellow, orangey), but without a view of the top of wings (to see yellow & brown bands) it is difficult for an exact ID as there are others similar to this in the Pieridae family of butterflies. 🙂 Here’s four shots from Calle Nueva, all 4 different colors (but I think the same species) . . .
This Barred Yellow, Eurema daira (my gallery link) was in bright sunlight and thus the nicer colors that you can find in my gallery weren’t seen on that morning. 🙂
