This is the Sunburst Candy Spider from Thailand. Not AI (sucks to have to declare this). Very real and had been on my wish list for a long time.

The taxonomic placement is unclear, so we are leaving it at Cyrtarachninae.

Hello everyone!

One of my colleagues and probably one of the best supervisors I've met, Dr. Iliana Medina, is advertising a PhD position involving lots of bugs and many different colours! More info in the image below, do share this widely!!

PhD opportunity in Melbourne, Australia, working in ecology and evolution of coloration with Iliana Medina (not on Bluesky). I can't recommend enough working with Iliana and living in that great city. Happy to chat if someone wants more details.

Been looking for a fresh specimen of Leucauge sarawakensis for a long time! Each time we found one, someone walked into its web. Hence, the ex situ shots.

NSF unexpectedly changed (at the last minute) who is eligible to apply for the Grad Research Fellowship, dropping 2nd year students. We started a petition to reverse this unfair change, Sign here:

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

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 🐙🌿

It was a pleasure to be involved in this!
📢🦋 Our paper ‘Global selection on insect antipredator coloration’ is out and featured on the cover of @science.org

We ran a huge experiment to find out how ecological context favours camouflage and warning colouration as antipredator strategies. 1/6

At the same time, we made thousands of synonymous mutations in endogenous yeast genes and measured their growth. We used careful statistics and controls. Only 3%, 204 of 6874, had a fitness effect! This goes against a controversial recent result that most synonymous mutations had fitness effects.
