Grand Caverns continued
First up is a bit of animal scratching on the wall
A springtail (Collembola) non-cave adapted and a mosquito-like thing photographed on the surface of a cave pool (click on the photo and you will also see that the blob in the middle is also a critter of some sort). Of note, finding small things on the surface of water in caves is actually a good way to find what lives in the cave.
This spider, maybe two millimeters in body size, was spotted on some dry calcite. Okay, technically this is an Opiliones, popularly known as harvestman or daddy-longlegs, and thus I probably shouldn't call it a spider even though most folks think of them as such. NEW: I have an ID. This is Erebomaster weyerensis
And to finish, some hydromagnesite balloons. I will put up more pics of this bit at some point.

Are you sure about that Blog spider? It looks suspiciously like a segmented abdomen to me, which spiders don’t have, except in the Palaeozic and a single weakly segmented family in s.e Asia.

Technically, no, it is a harvestman which is Opilines instead of a spider which is Araneae, but most folks call a daddy-longlegs a spider anyway.
