🧵Arachnophobia, while common, is unique amongst phobias bc often invokes an overlap of fear and disgust! This is not prevalent in other arthropod phobias. Interestingly, fear & disgust utilize the same neural network and have similar outputs, making them difficult to disentangle.

Arachnophobia is interesting to me because it's so specific. Like, people generally aren't afraid of crabs, even though they're hairy and skitter around. And they're not afraid of bugs, even though they have about the same number of eyes. Most people will never even see a dangerous spider irl.

Day 3 of #arachtober. I can't promise I'll keep this up all month; I'll run out of photos soon, but for now here's another Araneus diadematus to delight you. This was a nice, dark form, but yet again, it was facing the wrong way 🙄 @britishspiders.bsky.social #macro #omsystem #macrophotography

super cool study found human artifacts in Bearded vulture nests, incl. "weaponry like a crossbow bolt and wooden lance, decorated sheep leather, and parts of a slingshot....a shoe made from twigs and grass is ~675-years-old." link to paper: doi.org/10.1002/ecy..... www.popsci.com/environment/... 🧪🌍🦉

Join us in celebrating Arachtober by sharing your #spider and other #arachnid photos all month. #Arachtober has spread around the web. We’ve created a basic site at Arachtober.com to explain what this is all about. Banner by @ashleymbradford.bsky.social, inspired by my recent linocut artwork.

Remembering Mark Elgar, a brilliant mind in #BehaviouralEcology. His work reshaped our understanding of animal behaviour, and his warmth and mentorship inspired generations. A true loss for science & community.

I found this rove beetle friend on the rainforest floor. They are so so fast, you can imaging me chasing it around with my camera just rolling around in the leaf litter. Just unbelievable colors. In person the rainbow iridescence is stunning. It’s hard to say much here beyond just wow.

Thrilled our paper is finally out! A great collaboration between @mcaterino.bsky.social, Ernesto Recuero, and myself. We looked at endemism in spiders in southern Appalachia (largely NC).

This is also likely the most species-rich phylogeny (although just COI-based) of linyphiids yet published!

High elevation litter spiders of southern Appalachia show less local endemism than other arthropods - ballooning by spiderlings apparently overcomes geographic isolation. A great collaboration with @forthespiders.bsky.social & Ernesto Recuero

One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Centromerus denticulatus and Centromerus tennapax (both mostly golden brown with gray abdomen, both males with enlarged palps), Bathyphantes bishopi (dark brown cephalothorax, long legs, dark gray abdomen), Tenuiphantes sabulosus (golden cephalothorax, long legs, pale dark-striped abdomen). One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Collinsia sp. and Collinsia oxypaederotipus (both with light brown cephalothorax, pale legs, gray-green abdomen, both males with enlarged palps), Ceraticelus laetabilis (stout, with brown cephalothorax and lighter brown abdomen, palps slightly enlarged), Ceraticelus fissiceps (orange cephalothorax with distinctly enlarged dark snout, lighter abdomen). One fourth of a phylogenetic tree of southern Appalachian spiders, with photos of four representative taxa along the right side, Sisicus n. sp (not yet described, light brown round cephalothorax, with pale abdomen and legs, large male palps), Floricomus praedesignatus (dark tuberculate male cephalothorax, gray-green abdomen, pale legs), Blestia sarcocuon (anteriorly pointed cephalothorax, dark with long yellowish legs, impressive male palps), and Ceratinops carolinus (prolonged elevated, brown male cephalothorax, gray-green abdomen).

In a new publication, we focused on the little-known African spider Megaraneus gabonensis, in which females are 4x larger than males.

We provide an overdue taxonomic description, phylogenetic placement, and reconstruct the evolution of sexual size dimorphism.

Taxonomy, phylogeny, and size evolution in Megaraneus
Many spider species show large differences in size between males and females, but biologists still do not fully understand how or why this evolves. In this study we focused on the systematics and evol...

let me share a little story about a remarkable wasp that I encountered yesterday in our local deserts

I stumbled across her, and scrambled to get a few crappy photos .... but then realized that she had a burrow, perhaps a better photo op was possible ??

here she is at her burrow entrance.

gotta be a long-jawed spider then!

Reminder! The deadline for our infographic competition is the 18th of October. The last day of #biologyweek You can find out more information here www.asab.org/education-news There are three age categories: 7-10 years old, 11-14 years old and 15-21 years old.
This 2025 competition is for young people to design a poster that contains images and information about the animal behaviour of one, or multiple species of non-human animals.

You can draw, paint, sketch or digitally create artwork that captures, describes and explains the behaviour of animals. There are no restrictions on the type of drawing, painting or poster that you create, it must include information on the behaviour of the animals you are highlighting. The winning infographic in each category will be published in our scientific journal Animal Behaviour.

EVERYONE STOP

cheese wheel of cheeses
A circular infographic chart categorizing cheeses by type of milk and texture. At the center, four sections are labeled cow, sheep, goat, and buffalo, radiating outward into concentric rings for textures: soft, semi-soft, semi-hard, and hard. Each cheese name is placed within its corresponding segment, with illustrated wedges of cheese circling the outer edge. Cow’s milk occupies the largest portion, featuring well-known varieties like Brie, Camembert, Taleggio, Havarti, Gouda, Cheddar, and Parmesan. Sheep’s milk includes cheeses such as Roquefort, Manchego, and Pecorino Romano. Goat’s milk features options like Chèvre, Crottin de Chavignol, and Humboldt Fog. Buffalo is represented by Mozzarella di Bufala Campana and Buffalo Blue. The cheeses are organized visually so that softer varieties appear closer to the center and harder ones toward the edge. Small colored drawings show each cheese’s texture, rind, and tone, from creamy whites and soft rounds to golden blocks, crumbly wedges, and blue-veined interiors. The background is a deep charcoal gray, making the warm oranges, yellows, and creams of the cheeses stand out clearly.

It's #Invertefest, it's Saturday night, so... here's a couple of nudibranchs who are having a very good Saturday night indeed!

Chaimberlain's nembrotha (Nembrotha chamberlaini), Anilao

#MarineLife 🌿
Two nudibranchs on an algae-covered rock. One faces towards the camera, the other faces away. They have red rhinopores and gills, and a white body with a large irregular dark green patch on the back. There are small yellow patches around the edges of the green areas. They are joined by a purple tube, which is how nudibranchs mate; they are hermaphrodites and so each uses the tube between them to fertilize the other's eggs.

Out in the CNMI here, where I currently am, the best answer I know of is the local Golden Huntsman, Olios sp. Relatively abundant among the spiders here, but undescribed regardless.

#InverteFest #spiders 🌏🧪
Photo of a pale yellow huntsman spider underneath a leaf. It is relatively small compared to most well-known huntsman species at about 1-2 inches in diameter. It has fuzzy legs, a gray abdomen, and a bunch of tiny black eyes on the front of its face.

Ok #InverteFest, what's common in your area but likely new to science?

This slug moth caterpillar comes in the hundreds in my backyard, their poop accumulates on leaves. When the wind rustles, the poop comes pouring down and sounds like rain. Its identity is currently unknown beyond "Scopelodes".
a blob of long, chonky, green caterpillar covered in caltrop-like spikes. near the butt end is a band of white, yellow, and dark blue condensed together, almost like the stripe on commercial tooth paste.

This video is from a guest on my tour this week. I was busy taking stills. This is very much a wait for it video because the cutest part is at the end. It was absolutely magical to be able to watch these polar bear cubs and their mom just going about their day on the tundra in the rain. 🌿🦊🐻‍❄️
