I found eight of these perching on the sides of rocks in and near a small dry wash. (In the second picture, the net handle points to the fly.)

Specimens in hand keyed out to Wilcoxia in Wood 1981, and specifically to Wilcoxia flavipennis in Pollock and Reichert 2019 (species newly described, not in iNat taxonomy yet).

Dozens of these out perching on bare twigs at shoulder height.

I'm not good with caterpillars, so this is just a guess. AI favors a Heterocampa, but it doesn't really match any that I've seen.

Picture sent to me of a caterpillar my nephew found on a walk.

Seen while camping with the Mongolian Aquatic Insect Survey. Site is estimated from notes; probably MAIS2010070702 collection site at Uvs Aimag, Khovd Soum, near bank of Khovd Gol near bridge at Khovd; TAM_100, CRN 9659.

This looked like an agamid to me, and the color patterns seemed close to those of Phrynocephalus versicolor I found online. but it looks like the taxonomy of that group is still being figured out and I'm not an expert.

The pictures and specimens we had for this species in my herpetology class didn't do it justice. When I finally saw one live, I was taken aback by how breathtakingly beautiful they are. Such an explosion of color-- orange! yellow! blue! purple! black! tan! I especially love those scales like little sunsets on the dorsum.

These guys are really abundant on the beach dunes. You recognize them by the all white hairs, dusty grey tomentum, relatively long scutal bristles, and small body size.

Noticed this feller wriggling through a gap between the sidewalk slabs in the middle of UT campus at night and thought it was an earthworm at first. Seeing scales soon set me straight on that, but then I had to puzzle through the fact that it didn't have the typical snake head-- no (apparent) eyes, no tapered snout. Crouching over the edge of the sidewalk eventually caught the notice of a nearby cop, who came over to make sure I wasn't drunk and incapacitated. He didn't know what to make of my unbridled enthusiasm for a (harmless, and by then hidden) snake! And all the while my dad was waiting patiently on hold on my pocket (I had been talking to him on my cell when I noticed the snake). A nice bit of serendipity to add to my life list.
There had been a misting of rain in the hour before this guy came out.

Driving through the mountains, we spooked a golden eagle that was perching on a forest service road. When it took off, it dropped this impressive mostly-dead rattler and then perched nearby to watch us (see second photo). Note how the head was mauled, but within a few minutes this snake scared us all by starting to rattle, then starting to slither, then trying to eat every rock in his agony-laden path.
I'm guessing this is Crotalus oreganus, the great basin rattlesnake, but I'm no expert.

Lots of these on the sandy riverbanks; specimens in my collection. Lasiopogon ripicola can have a variety of color morphs, with white, black, or mixed mystax hairs. But note the broad grey bands on the tergites, the strong dorsocentral stripes on the scutum, and the relatively rounded epandrium.

From my notes: "These were perching on sticks and logs on the ground. The area is open, where power lines cut through the forest near a big bedrock reef; within 50 m of a stream. Sandy/leaf litter substrate."

Don't know what the prey is. This is a good, reliable population; they've been here every year for the last decade.
