And the award for "best arachnology paper title of the year (so far)" goes to...
Bellvert, A., Nicolosi, G., Pavlek, M., Cresi, L., & Mammola, S. (2026). "Where We’re Going, We Won’t Need Eyes to See: Distributional Range Size Drivers of European Subterranean Spiders." Journal of Biogeography, 53(5). https://doi.org/10.1111/jbi.70237 :OpenAccess:
(Part of their aim is to "assess the impact of cave-related phenotypic traits (eye reduction, leg elongation, and pigmentation loss) on species distributional range".)

people! i'm gonna actually make an #Arachnews blog post. Got any recent-ish arachnid photos/art you want to show off and will give me permission to use? I would like to add it to the post! Just let me know how you'd like to be credited.

New research from the Hebets Lab at University of Nebraska Lincoln: _Agelenopsis_ grass spiders in noisy urban environments weave webs with built-in noise dampening—as opposed to their rural cousins, who built more sensitive webs when researchers turned up the volume.
From the NYT article linked below:
> “While animal sensory systems can, and do, certainly adapt over evolutionary time to changing environmental conditions, this takes time,” Dr. Hebets said. “Behavioral changes, however, can be immediate.”
This offers an intriguing tangent: webs are part of a spider's sensory apparatus but are constantly re-built, and behavioural plasticity lets them "evolve" much faster—an evolution you can't track by looking at physical traits alone.
Anecdotally, _Agelenopsis_ are masters at adapting their flat sheet webs to even the unlikeliest urban environments! So it's not a surprise they are adaptable in other ways as well.

> As of 2025, there are over 52,000 species of spider known in our plane of existence (World Spider Catalog, 2025), with many more awaiting discovery. This does not take into account spiders that may exist in other planes of existence, which, until now, have never been studied.
It's a bit early but this is quite possibly the best arachnid paper I've read, and will read, all year: Marc Milne & Shahan Derkarabetian construct a phylogenetic tree of arachnids in Magic: The Gathering.
If you don't know much about MtG, arachnids, or how biologists classify species, you'll definitely learn something from this paper!

Meet _Chilobrachys natanicharum_, a newly described tarantula from Thailand with legs that iridesce with "a blue-violet hue resembling the color of electrical sparks". You seriously gotta see this. https://zookeys.pensoft.net/article/106278/ :OpenAccess:

- a new high-level #phylogeny of #Solifugae, the bizarre and enigmatic arachnids known as "camel spiders", "wind scorpions", "sun spiders", and so on. From Siddharth Kulkarni at UW-Madison's Sharma lab and featuring all the usual suspects in the authors list, like solifuge expert Paula Cushing, Efrat Gavish-Regev, Danilo Harms, etc. :OpenAccess: https://doi.org/10.1016/j.isci.2023.107684
- #tarantulas (family #Theraphosidae) in the wild in Argentina! Including many Plesiopelma aspidosperma and "the first published color photograph of an adult specimen of Cyriocosmus versicolor based on a reliable taxonomic identification". 🔓 https://www.researchgate.net/publication/373649580

Some #OpenAccess :OpenAccess: arachnid research from the ol' Google Scholar alert:
- Gotta love a good arachnids-eating-vertebrates article (and to no surprise, it's reptiles/amphibians). Enjoy the photos of spiders and scorpions eating frogs and lizards in Mexico & Costa Rica. https://www.researchgate.net/publication/366953189/
- New silk research out of the Blackledge lab: anchor lines (a feature often left out of spiderweb models/simulations) double how much energy _Micrathena_ orbweaver webs can absorb. https://journals.biologists.com/jeb/article/doi/10.1242/jeb.245123/286587/

#Arachnews: folks at Gabriele Uhl's lab have discovered that male wasp spiders (_Argiope bruennichi_) have special sensory organs, called wall-pore sensilla, on their legs which they use to smell females' airborne pheromones. They also found wall-pore sensilla in other adult male spiders, and evidence suggests they evolved independently across the spider tree of life. Many questions still remain about spider smell!
