An evening discovery

So, last night I went out to the movies and left poor Mary home alone — it was a creepy movie, she doesn’t like that sort of thing — and she found her own entertainment. She found a spider in the garden! When I got home around 9 she had to send me out to take a picture of it and identify it.

That’s the Eastern Long-Legged Cobweaver, Theridion frondeum, that I’ve seen many times around here, but they’re very pretty.

How do they avoid motion-sickness?

This little orbweaver was just sitting innocently in her web, and I don’t know how they do it.

The thing is, when they’re on that web and the wind is blowing, they’re just vibrating all over the place. You’d think they’d be hopelessly motion-sick.

I couldn’t stand it so I let her take a break from the gale on my finger.

Don’t worry, I returned her to the same branch.

Trogloraptor!

A new species of spider has been identified.

We present a morphological description of a recently discovered species of spider in the family Trogloraptoridae from the Columbia River Gorge in northwestern Oregon. The family was previously monotypic (Trogloraptor marchingtoni) and only known from populations near the southwestern Oregon—northern California border. Trogloraptor tulishpun sp. nov. retains the key family synapomorphy, distinctive subsegmented raptorial tarsi, and an oblique membranous division of the basal segment of the anterior lateral spinnerets. Trogloraptor tulishpun is distinguished from T. marchingtoni by its color pattern, clypeal height, vulvar and palp structure. We have found T. tulishpun in four localities in the Columbia River Gorge, which show little mitochondrial sequence divergence from one another, but are highly genetically distinct from T. marchingtoni. Trogloraptor tulishpun is found in basalt features, including lava tubes and shallow talus caves, and has been observed to eat arachnids and moths, making them top predators in these environments.

First, that’s a truly awesome name, Trogloraptor, for a cave spider. Somebody hit a home run with that name.

Naming a new species isn’t a trivial thing, but the lab that found this one went above and beyond to come up with the name Trogloraptor tulishpun. They consulted the local people of the Yakama nation, and got the name “tulishpun” from them. And then they had a formal naming ceremony, as reported on NPR.

ANTHONY WASHINES: At this time, we’ll open this ground, the sacred ground that we’re standing on, and then we’ll begin.

PRICHEP: Naming ceremonies are usually, unsurprisingly, for people. It’s a formal introduction of the name, but it’s also a way to sort of welcome that individual and mark their place in the community.

WASHINES: You’re being a witness to this brother being acknowledged.

PRICHEP: Anthony Washines is the Yakima elder who came up with the spider’s name.

WASHINES: And so, from this day forward, we will call them by the name tulishpun. Repeat after me – tulishpun.

UNIDENTIFIED CROWD: Tulishpun.

PRICHEP: Gifts and food were shared, and a traditional naming song was sung. A few spiders were gathered to receive their name and then returned back to the nearby caves. Washines knows people will see tulishpun as a small thing. But he says every creature has its place, and this little spider has been in this place even when his people were not.

WASHINES: We were literally herded to a reservation up in the high-desert plateau, which was not our land. But he stayed here and remained. He still took care of this land.

PRICHEP: Usually, the discovery of a new species is celebrated with a pizza party in the lab, maybe a nod from the dean. It’s an academic milestone. But for tulishpun, it’s a community event, a gathering of scientists and citizens, of human and animal, to name all of those who make up this land and honor the connections between them.

How lovely. I’ll keep that in mind if I ever discover a novel species, which is extremely unlikely. In my background, we didn’t go looking for new species — new mutations and new molecules, sure, and we had ceremonies, usually involving popping a champagne bottle, when a paper was published, but we lack a connection to the community, the people, and the land. A species, though, is something people may have interacted with before, and that interacts with other levels of its biome, and it is appropriate to add a scientific context to a known part of our world.

Still exaggerated

I appreciate the message that most spiders are harmless, but it’s still too much to claim that 2 are dangerous. They’re not.

I haven’t had any opportunity to work with recluses, but widows are shy little sweethearts. They have a potent venom, but they’re seriously reluctant to use it. I let mine scurry all over my bare hands and arms, and have never been bitten, because I treat them gently and with respect.

I’d say of 3,000 species, there are 3,000 to be cautious about, and none to be afraid of. Save the fear for dogs and cats, which are much more dangerous.
