Black leaf cutter ant. Cool!
Two females, which appear to be adults, under rock beside trail, on south exposed hillside in aspen pine forest.
Found in very fine soil, as is usually the case. Nest entrances were very inconspicuous, a small hole in the ground (sometimes even too small for the majors to fit their heads through), usually with a small debris/trash pile an inch or so away. Majors occasionally peeked out of some of the nest entrances but never wandered more than an inch or two away from it. Majors were not found foraging.
There were multiple nest entrances in the area, probably from the same colony. It made it difficult to do an exact count of how many were in the area. Nest entrances were found at night and had little activity, but in the early morning they were much more active. The rain from the night before and consistent cloud cover probably helped.
Super cool to finally see these.

This individual was enormous!

I use the type locality for the observation.
Just upload some photos of higher resolutions of my paper.

These things are creepy. And fast. And creepy. Scutigera coleoptrata, according to Wikipedia
Seen while on a "Hall of the White Giant" training trip. Seeing this creature this far down and far from the public trail was a surprise. Photos by Kevin Chesak.

Same spot as Tuesday, but this one has the full flagellum. These seem to be somewhat common at BFL--I saw them down closer to the river as well in a completely different soil type.
Androctonus cf. bicolor.
The surveillance data is not mine, but my colleague's. He was in Libya and was able to find this scorpion, then he gave it to me and allowed me to post this observation.
The photos are mine, I took them at home.
Under stone in litter, shallow slope under Quercus agrifola. An egg appears to be stuck near the flagellum.
Update: Dr. Monjaraz-Ruedas pointed out that the egg is too small for a schizomid, and is probably from a parasitoid.
Observation for the egg: https://www.inaturalist.org/observations/160617888
