Not real common, though I’ve seen at least 3 other times in my garden, the Eastern Tailed-Blue, Cupido comyntas (linked to my gallery) has before been almost totally blue on top with less brown than this one, but with research, I’m confident that this set of photos is properly identified, even though Ceraunus Blue has more brown like this, it has a totally different set of black dots. Plus one article says that females are more brown, so maybe this is a female! 🙂 And all photos are of the same individual. Plus, interestingly, every time I’ve seen this species, it has been in grasses and never yet on a flower. 🙂 Here’s 3 photos . . .
Read more about this species on Wikipedia and though they say they are only in the Eastern U.S., they are definitely found in Central America and hopefully that article will be updated. See the range map on BAMONA.
¡Pura Vida!
