Las Vegas, NM Flora:
and Some of the Associated Spiders et alia

Abandon all Arachniphobia, all Ye who Enter Herein.
The hairy many-eyed and fanged beings dwelling here
are searching smaller prey than thee.

Science estimates the total world human population weighs 287 million metric tonnes;
another group of scientists estimate that the total weight of all the insects eaten
by all the spiders in the world is 400-800 million metric tonnes. The earth needs them!

..the one species the world does not need is Homo sapiens,
well maybe, if we could learn to live with all rest of creation.

Let's find a SPIDER!

I was not surprised as it was not an uncommon occurrence. Usually we just flush them down the toilet because they look similar to the Brown Recluse and Roy, once a neighbor, was bitten by an alleged out of range Brown Recluse which resulted in a necrotic flesh wound taking a long time to heal. So why worry? but now that I am making the acquaintance of as many of my fellow beings in my neighborhood as I can, I plucked him out of the bath tub and into a gelato tub where I could get a good look. I photographed him, then froze him so that I could get some close-ups, he just would not sit still. After reading up on this guy, we'll continue to flush, unless I get a female, then photograph and flush.

Its webs resemble cotton candy, and entangles prey rather than traps it with a sticky glue, Bradley says. The orb weaver uses the silk and its powerful legs to squeeze dinner to death, then sticks its hollow fangs inside, spits digestive enzymes with its mouth and sucks the emulsified insides back out.

Uloboridae in N.Amer N of Mex Muma & Gertsch, 1964: Uloborus oweni pp.31-2, 34-5

The Uloboridae family is the one North American spider family without any venom at all.
Its webs resemble cotton candy, and entangles prey rather than traps it with a sticky glue, Bradley says. The orb weaver uses the silk and its powerful legs to squeeze dinner to death, then sticks its hollow fangs inside, spits digestive enzymes with its mouth and sucks the emulsified insides back out.

Mitopus morio
18 May 2019

I recently had remarked that I had not seen any Harvestmen (known as Daddy-longlegs in my youth) here in NM. A few days later there was this one climbing on the blue road divider by the Riverwalk north. When he got on the near vertical slope he slid down to the ground, claiming my notice.
