Though I’m not seeing as many as last June, the variety of butterflies is slowly expanding in my garden. We got almost no rain in May and now it rains every afternoon, which is normal for rainy season, but if anything different this June it is maybe more rain than last year, which may or may not affect the number of butterflies. And I’m also getting fewer birds. Here’s photos of 5 different species seen in the last week.
My best printed source of butterfly identification is the book A Swift Guide to Butterflies of Mexico and Central America by Jeffrey Glassberg. In that book this butterfly is labeled as a “Bright Scintillant,” but rather than giving a scientific name, it just says it is one of the “Calephelis species.” The butterfly website I volunteer for (butterfliesandmoths.org) does not have Bright Scintillant nor does its backup website, butterfliesofamerica.com, therefore I and others have put this one in “Rounded Metalmark, Calephelis peritalis,“ a part of the “Calephelis species” as the book says. But according to the Glasberg book, the white dots on the upper edges of the the forward wing make this one different from the Rounded Metalmark in the book. I do not know who is the final authority on butterfly names, but hope this one is at least made a subspecies of the Rounded Metalmark! And identification of the myriad of butterflies in Costa Rica will always have its challenges like this! 🙂 Here’s two shots of the latest I have seen of the above butterfly in my garden . . .

Thel Rounded Metalmark or Calephelis perditalis is one of several Metalmark butterflies still around my yard late in the season. Like the Satyrs, they stay close to the ground and seem to prefer grass over flowers, thus the wind blowing is not as much of a bother to them. This one is quite colorful and with intricate design work on sides, thus I include a top view, bottom view and a folded-wings or side view.
