Blue-spotted Hairstreak

Instead of such an obvious “Common Name” (above) the source website names that I have to use for BAMONA, which doesn’t already have this butterfly in their database yet, is whatever BOA (butterfliesofamerica) has in their listing and their “common name” is Augustinula Hairstreak with the scientific name of Denivia augustinula. So that is the ID you will find in my personal gallery (which I try to keep in sync with butterfliesandmoths). In my gallery I have more photos from this past Sunday morning’s new discovery for me at Augustinula Hairstreak Gallery where there is an interesting rear shot with a long shadow of the insect. 🙂

For the serious student of butterflies, the Glassberg book uses the common name of “Blue-spotted Greatstreak” and another scientific name used online: Theritas augustinula. Plus, for what it is worth, I found a 3rd scientific name being used online of Thecla augustinula. :-) You can see why identification sometimes drives me crazy! 🙂 Just one photo here and you can go to my gallery for more.

Cassius Blue – A New Species!

That is . . . a new species for me to photograph! There are so many species of butterflies in Costa Rica, about 1500, that my butterfly gallery of 260 species barely shows the huge variety here! This tiny butterfly landed on an equally tiny wildflower for just a few seconds and was gone! Because he is one of the “Blues,” the top side of his wings will be some shade of blue, but I did not get to see or photograph that and he was even partly hidden behind a portion of the flower. Maybe I’ll see this one again soon.

He has been seen spottily across the U.S., though mainly in Florida and Texas and on south through Central America. See the location map on ButterfliesAndMoths. Here’s two shots I got in my garden.

Eastern Tailed-Blue

This Eastern Tailed-Blue (Cupido comyntas) is a cousin of the Ceraunus Blue (linked to blog post) I shared a few days ago, another sub-family in the Gossamer Wings or Lycaenidae Family (linked to that group of galleries) of butterflies and another one of those very tiny ones, as noted by him being on a blade of grass in these photos. :-) Most in the Lycaenidae Family are tiny. Also he’s called a “blue” because the top of his wings are a powdery blue, though barely seen in just one of these photos. Because of the wind this time of year he keeps wings folded when landed, but you can see my photo of another one with open wings in my Eastern Tailed-Blue GALLERY where all the photos have come from my garden. 🙂 And also note that with my eyes he looks white, but the light and/or camera give him a brownish hue this time that I cannot explain.

White Peacock Avoiding the Wind

White Peacock – Anartia jatrophae – I always prefer photos of the tops of their wings when open and spread out, but we have so much wind this time of year that they won’t risk being blown away by keeping their wings folded every time they land and even then their folded wings are like a little sail sticking up. :-) Though not as common for me as the Banded Peacock, they are fairly common all over Costa Rica on both slopes as you can see in my White Peacock GALLERY, though so far only at lower elevations. Here’s two shots from my garden the other day . . .

Ceraunus Blue

This tiny little butterfly was new to me in a September 2022 sighting at Hotel Banana Azul in Caribbean Costa Rica, which I saw again there and in my garden in 2023, Ceraunus Blue, Hemiargus ceraunus! I liked it so much I chose one of my garden shots for the cover of my newest butterfly book, Pura Vida Butterflies, Second Edition released last month.

Of course I also have a Ceraunus Blue GALLERY with shots from all four sightings. Now here’s what I saw the other day in my garden, with two shots, even though not as good as my earlier photos :-)  . . .

Cerulean Dancer Damselfly

The Cerulean Dancer Damselfly (Argia anceps), male here, is one of dozens of blue and black damselflies with this one most often confused with the Azure Dancer and the Thorn-tipped Dancer (says the book), but because of the shade of blue, the size and the wing color I am declaring this a Cerulean Dancer! :-) But to be honest, with both damsel and dragonflies, I am seldom 100% certain of the identification and I use a Costa Rica specific field guide with nearly 300 species of damselflies and dragonflies included with photos! You would think that makes it easy, but not for me! The many similarities between species makes identification a challenge for many! This one was photographed on the railing of my terrace in Atenas, Alajuela Province, Costa Rica.

See my Dragonflies & Damselflies GALLERY with 50+ species! And many are unidentified! :-)

Plain Longtail with Orange Smudges?

I continue to find what appear to be “new” species for me, though this one is pretty much identical to the “Plain Longtail” with the exception of a slightly shorter tail (he could have broken off the tip as he did the 2nd tail) and the “orange smudges” on the wings, large on top and smaller on bottom or side view. I’ll label this the Plain Longtail, Urbanus simplicius and let one of the coordinators at butterfliesandmoths correct me if they believe otherwise. These little detailed differences continue to be an ID challenge for me! 🙂 Here’s 2 shots, one side view & one top view . . .

Saltbush Sootywing

Saltbush Sootywing is the common name and the scientific name is Hesperopsis alpheus. This is a new species for me. And my ID is based on the Glassberg book where it is an exact match, but my photos don’t match the ones on butterfliesandmoths.org for this species, so I will probably be flagged and if so, I hope whomever can give a good identification for this butterfly, IF this ID is not correct. Note that the two photos are of the same insect on the same leaf within seconds apart, but the changing light or capture of the camera has them as two different colors. 🙂
