Spiders get around

Michael Caterino @mcaterino.bsky.social · 9d

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 three representative taxa along the right side, Wadotes hybridus (reddish brown cephalothorax with zig-zag stripey gray and white abdomen), Neon nelli (large-eyed gray jumping spider), and Antrodiaetus sp. (a large-jawed mygalomorph trapdoor spider, light tan with a reddish abdomen.

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).

A red and black beetle with wings extended appears to be taking off from a green, leafy plant. The background is blurred, highlighting the insect amid foliage in the foreground.

I asked a student worker for an alphabetized list of families in a cabinet. Naturally he asked #AI to do it and then explained to me that Chat made some mistakes, but it was close enough. The kids might actually be doomed.

Hey I started a new section of my website called Derek's Tech Corner, come check it out: www.derekhennen.com/derekstechco.... It's where I'll share various software and other tech tools for cool kids that will save you time--so that you can go look for more bugs.

It's a weird take that time stops during a PhD and you'll somehow emerge with outdated knowledge. You'll never be as on top of a subject as you are during grad school.

Those mud flats are terrifying. You only need to hear one bad story to stay away.

The aedeagus (male genitalia) of a common eastern US Pselaphine beetle, Arthmius globicollis. The genitalia have never been illustrated, so species identification has always been dicey. The left one is from South Carolina, the right from Missouri. Pretty different, maybe cryptically so.

micrograph of beetle genitalia - lateral view. There is a weakly bulbous basal piece to the left. The apical parts consist of an arched dorsal ridge, a bifurcate median fork, and a long, curving ventral process as long as the whole rest of the structure.

Witching hour at the lights last night.

The black witch (Ascalapha odorata) can grow up to 7 inches and is the largest #moth by wingspan in the US.

Two specimens of Megetra punctata from southeastern Arizona. Surprisingly the smaller one was a female and the larger a male - I think size is totally related to how much blustery ooze they have left in them and not correlated to gender. These things reflex bleed as soon as they are touched!

A large, seemingly inflated black beetle with orange red markings on it. The abdomen is blown up and it has tiny hardened front wings which don’t cover its body.

A smaller individual of the same species which seems to have had the abdomen shrivel up some.

The large individual curled into the fetal position with an orange glob of its toxic blood secreted around its head to avoid predation and hopefully deter entomologists. Unfortunately for him, I had forceps.

Had a great time teaching the insect field course in #Denali National Park

There are no cushy field stations in #Alaska. Students slept in wall tents and learned to pin and Id #bees in a yurt without electricity.
