Subspecies septemvittata, which is Big Bend Spotted Whiptail. This taxon doesn't exist as an entry for iNaturalist.
This is Chlosyne theona chinatiensis which some authorities consider a distinct species. On iNat it is regarded as a subspecies of Theona Checkerspot so that is where I will place it at present.
An incredibly beautiful little hairstreak. Spotted by Chris Tenney.
unknown dark moth feeding on milkweed flowers. I confess I was distracted by the Sandia Hairstreak
which was on this same blooming milkweek (and you can see in some of these shots), so I did not do justice to this little back moth. By the time I wanted to get some more and better shots of the moth, however, it was gone. Oh well.
Either Common Streaky-Skipper or Scarce Streaky-Skipper. Both occur here and I understand are not separable in the field.

A group of five of us: robberfly, maractwin, gcwarbler, Mary Gustafson, and greglasley, were participating in a Colima Warbler survey in Pine Canyon in Big Bend National Park. During our morning hike into the canyon we started hearing the distinctive paired notes of the call of a Northern (Mountain) Pygmy-Owl. We spent an hour or more trying to locate the owl, but it was well up on a rugged slope on the south side of the canyon, and we just could not see it. We were, however, certain of the ID and we were satisfied it was not some vocalization of a Rock Squirrel or anything else. The calls were recorded by gcwarbler, maractwin, and Mary with iPhones. We continued on with our survey and at about 1 PM we were walking out of the canyon and again heard the bird. We stood on the trail and searched the large pines across the canyon from our location, and Mary spotted the bird!!!, high in a Ponderosa Pine. I did not have a large telephoto with me as I was set up mainly for butterfly photography, but several of us obtained some shots from about 125 meters away. Image 1 is cropped so you can see the bird. Image 2 is not cropped and shows the view through my camera and lens (300 F/4 and 1.4X extender). Image 3 is highly cropped but makes the bird itself a little more visible, though badly pixelated. It was a long way off for photos, but in the cropped views you can see the long tail extending past the limb it was perched on. maractwin has another shot of this bird as well as a recording of the calls posted at:
robberfly also has an image of the bird at:
Several of us saw and photographed this same bird the following day and were able to show it to other birders. This will represent the 5th record of this species in Texas.
