The Washington Post is using bothsidesism to justify everything Trump is doing.

From yesterday on political purges in the military. They compared it to covid vaccine policies.
Alt text:
A screenshot of a paragraph from an article with white text on a black background. The text discusses Hegseth’s actions since taking office, stating that he has challenged traditional norms by saying as recently as last week that generals and admirals should resign if they don’t support the Trump administration’s policies. It compares this to the Biden administration’s coronavirus vaccine mandate, which led to the dismissal of thousands of troops.

“This is not just an administrative headache. It puts patient care at risk in an already overburdened system. Medicine is complicated enough. We should not be leaving physicians and patients to guess whether a proven, widely used mode of care is legal, billable, or sustainable.”
Coverage for telemedicine has ended abruptly. For my patients and me, it’s a disaster
Telemedicine is a core part of care delivery. But on Oct. 1, patients and doctors lost access to it across the U.S.

This is Noir, the false widow living under my basement stairs, doing her best impression of a black widow. Probably Steatoda borealis. I love the little white crescent on these spiders 🌒 #arachtober

Consider the added cruelty of Medicaid work requirements (to be implemented in all US states starting in January 2027; previously implemented in AR & GA, resulting in coverage losses)-- on top of the possibility of having your wages garnished for bills that should have been paid by Medicaid.

A top Mamdani adviser tells me internal data shows taking on Trump's authoritarian abuses resonates. It appeals to working class voters across all demographics, countering the frequent claim that this is a "distraction" from issues working people "really" care about.

Inktober Day 2: Weave

Jumping spiders—tiny, fuzzy, lightning-fast poets on eight legs. I absolutely adore them. Whenever one visits my studio, I take it as a wink from the muses. Spiders have long been symbols of creativity, weaving blessings for imaginative souls.

This lil’ jumping spider is an avid writer, weaving tales most mysteriously. What stories are you weaving today?

Spooky season is #spider season!
Thin-legged #wolfspider - Pardosa sp.
(Shot near Cincinnati 9-19-25) 🐺🕷️ #photography #macrophotography #wildlifephotography #wildlife #nature #animal #invertebrate #arachnid #spidersky #ento
A female thin-legged wolf spider (Pardosa sp.) shot mostly top down with the spider facing the left of frame.  She is missing her rear-most leg on her right side and her second from the front leg on her left side.  Her lack of legs doesn’t stop her from carrying a big white egg sack with her spinnerrets on her brown abdomen.  The spider is a mottled brown with earth tones.

A rice-grain-sized male jumping spider, I think Habronattus klauseri (Arizona). I have another shot that's more face-on, but I like this image because you can see the soft hair on the face under the eyes. I also like the low contrast background and his side-eye, about-to-jump pose. 🐙🌿 #Arachtober
A macro photo looking into the face of a jumping spider, with a background of mostly straw-colored vegetation and pale rock. The spider has green eyes set in a mask-like band of orange-brown hairs, with a band of short white hairs below the eyes. The legs have a dark background color with many cream-colored hairs, and the inside of the legs show olive-green and muted orange.

It's that time of year again: #arachtober! I will try to celebrate as many days as I can. This spider is a Woodlouse Hunter, Dysdera crocata. She has long jaws and only 6 eyes (most spiders have 8). Leavenworth, Kansas, USA, April 28, 2025. #bugsky #spiders

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.

Carolina Wolf Spiders are found throughout North America. They typically live in burrows and hunt by stalking their prey. This is gorgeous female was found on a desert night hike near Portal, AZ. #arachtober

The regime is deporting an Atlanta journalist and being pretty open about the fact that it‘s in direct retaliation for his coverage:

“An immigration judge granted Guevara a $7,500 bond in July, but the government filed a stay, claiming that his reporting on law enforcement activity was dangerous”

One of the most valuable ways to support pollinators and other invertebrates is to provide them with the shelter they need to survive the winter. Thankfully, all you need to do is do less yard work.

Most "tarantula-like" (Mygalomorph) spiders can't use silk to balloon around, unlike "typical" (Araneomorph) spiders.
BUT. Ummidia trapdoor spiders can! (still only as babies, same as all spiders.) That's why theyre so widespread around the world compared to their relatives!

Here are some teeny tiny trapdoor spiderlings, found atop a plant stem getting ready to balloon away to find a new home. When I shot this, I didn't realize trapdoor spiders dispersed in this way - they're pretty chunky. But of course the babies are very small. (North Carolina) #Arachtober 🐙🌿

I have a vision! I would like to see them be the mascot for the 2032 Brisbane Olympics.
Pastel crayon drawing of a Peacock Jumping Spider on a twig, in bright primary colours. Where its two central eyes should be now the Olympic rings, there is a two person rowing icon on its tail-fan. Its third legs are up in a dance pose and its little leg pom-poms are exaggerated and colourfully matching its tail-fan. The drawing is by user - Talzir, the reference image is by photographer - Jurgen Otto.

I did not find these spiders at home (sadly), but they are the spiders who reignited my arachnid obsession, so I am honouring them with my first post. Meet Meta ovalis, the Eastern Cave Long-jawed spider. Found in Greig's Caves in Lion's Head, Ontario.
