#DailySpiderPic: I was thrilled to discover that there is a feather-legged or hackled orbweaver (family Uloboridae) in the lavender plant again this year—surely a child of last year's.
These spiders are unusual in a few ways: they have lost their venom entirely, and they make orb webs with cribellate silk that is fuzzy instead of sticky. (There are many spiders that make orb webs, and many that make cribellate silk, but only this family does both.) They are not rare, but I still think they are interesting.

NEW TRAVIS MCENERY VIDEO LET'S GOOOOOO https://youtu.be/2TE9xZDnvM8
(This one is on _Uloborus glomosus_, a venomless cribellate orbweaver, and is full of surprises!)

I was just poking around the garden today in a spare moment and had two unexpected arachnid discoveries!!
1. A hackled orbweaver (_Uloborus glomosus_), one of the very few venomless spiders, that also makes orb webs with a fuzzy, glueless silk not often used for aerial webs—I rarely come across them and never, I think, in my own garden.
2. A new kind of pseudoscorpion—not the tiny yellowish cthoniids I'm used to, but a HUGE beast with sturdy claws, like 3mm long! I think it's family Chernetidae.

Do you know that there are non-venomous spiders? This project started from a 1931 hand-drawn observation that Uloboridae spiders do not carry a functional venom system.
With histological, RNAseq and bioinformatics work led by the great Giulia Zancolli and master student Xiaojing Peng, we confirm that Uloboridae 🕷️ have lost venom glands , but find that they produce putative neurotoxins in the digestive gland. #EvoDevo #spider #Uloboridae #GeneExpression #venom #toxin
