Final version now out in @elife.bsky.social: Heterozygosity at a conserved candidate sex determination locus is associated with female development in the clonal raider ant (Ooceraea biroi) doi.org/10.7554/eLif...

New article from the lab out today, in which we discuss how social behavior evolves at the molecular level. From parenting across the animal tree of life to caste systems in social insects, it’s all connected (and, therefore, slowly starts to make sense)…

Lab members are once again outdoing themselves at the annual @rockefeller.edu pumpkin carving contest. This year’s submission: an ant farm pumpkin with a carpenter ant colony digging to find a chamber of prey Drosophila.

It’s mosquito o’clock apparently- here’s another cool paper about these unpleasant little blood suckers (with, it once again turns out, really interesting adaptations):

What does mating look like when you only have a single shot at getting it right? Very excited to share our work on an almost-invisible female control, rapidly evolving mating recognition systems, and species that break the rules and take over the world. IN MOSQUITOES>

New preprint from the lab: A reference brain for the clonal raider ant. With this resource, which is based on 40 individual brains, you can register and compare all kinds of samples in a common space. It comes with lots of detailed protocols and a user-friendly GUI. www.biorxiv.org/content/10.1...

New findings solve “developmental biology’s most complicated problem”: how each olfactory neuron in the ant expresses exactly one out of hundreds of olfactory receptors. By @vcallier.bsky.social #neuroskyence www.thetransmitter.org/sensory-perc...

Don't miss this piece in @thetransmitter.bsky.social by @vcallier.bsky.social on @danielkronauer.bsky.social's latest work! His lab discovered that a protective screen of spurious transcriptional activity enables each olfactory neuron to express exactly one out of hundreds of olfactory receptors.

A study from the @danielkronauer.bsky.social lab has revealed a new form of olfaction gene regulation that may be broadly shared across insect species—opening up a new window into studying connections between genes and social behaviors. Read a Q&A with the scientists:

I’m petrified about today’s science news. Genetically modifying crabs to have cheetah genes? This could go sideways fast.

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.

A new study in ants from @danielkronauer.bsky.social reveals a previously unknown mechanism that ensures that each olfactory neuron expresses only one odorant receptor, with broad implications for the study of gene regulation. #RockefellerScience https://bit.ly/4pwPFLY

The final version of our paper on how ants and possibly other insects use a crazy mechanism involving extensive transcriptional interference to regulate odorant receptor expression is now open access in my favorite journal, @currentbiology.bsky.social authors.elsevier.com/sd/article/S...

Ant reproduction is getting weirder and weirder. Here’s the latest: queens of a Mediterranean harvester ant mate with males from a different species and then lay eggs that clonally inherit those males’ genome. I.e., they lay eggs that develop into a different species. 🤯

Finally, an ant photo from my recent Kenya trip. On Mount Kenya, you pass through a zone of pristine rainforest, which is where I’ve previously worked on army ants. There are other cool ants though, and here’s an example. The dark sphere in this tree is a carton nest of Crematogaster acrobat ants.

If you’re interested in ants, olfaction, gene regulation, or all of the above, here’s a new preprint from the lab for you. It describes an unorthodox mechanism of transcriptional interference by which ant olfactory sensory neurons produce a single functional receptor. www.biorxiv.org/content/10.1...

Applications for faculty positions at Rockefeller are now open! We are seeking exceptional, creative scientists to join our faculty. Learn more below:

What a loss!

A black panther! Melanistic leopards are extremely rare in Africa, and seeing one on our recent trip to Kenya was a dream come true. We were able to spend an hour right before sunset around this marvelous creature while staying at Mpala Research Centre in Laikipia.

Sleeping hippos look like they’re smiling. Here, a group is resting on a river bank at Mpala Research Centre while being attended to by red-billed oxpeckers. These birds eat ticks off of large mammals, but also drink blood directly from wounds. 🦛 🇰🇪

The Grévy's zebra (Equus grevyi) is the largest and, sadly, rarest of the three zebra species. Luckily, Mpala Research Centre is home to a decent number of Grévy's zebras, which are studied as part of a long-term monitoring program: www.mpalalive.org/field_guide/... mpala.org/princeton-ze...

A hyrax with its little one. These cutie pies were living right outside our cottage at Mpala Research Centre. 🇰🇪 Apparently it is World Elephant Day. So why hyraxes? Unlikely as it may seem, hyraxes are elephants’ closest living relatives.

Some of the animals at Mpala Research Centre 🇰🇪 participate in ongoing projects. Here are vulturine guinea fowl studied by @[email protected] at the MPI for Animal Behaviour. They are individually marked and some are wearing solar-powered GPS tags. More info is here: mpala.org/vulturine-gu...

New research from @danielkronauer.bsky.social's lab in @pnas.org sheds light on how a young ant’s future is determined by genetics and the environment, finding that genes not only influence size, they change what a given size means for the colony. #RockefellerScience

Congratulations to this year’s Hamilton Award winner, Kip Lacy, and Honorable Mentions Meagan Clark and Jeremy Summers! www.evolutionsociety.org/news/display... Watch their outstanding talks from virtual #Evol2025: www.youtube.com/watch?v=Mzh3...

Massive congrats to @mendelslols.bsky.social for this very well deserved honor! 🍾🎈

Ant fathers are vastly under appreciated. OK, they die right after mating and don’t contribute much to colony life beyond their role as “flying sperm vessels”, but still, a single male can father thousands of daughters. Let’s wish this Camponotus americanus carpenter ant male a Happy Father’s Day.

Happy Father’s Day everyone! This tree swallow (Tachycineta bicolor) is being a good parent by literally stuffing its chick with yummy insects. Woodstock, NY.

Just saw this. This couldn’t have happened to a nicer and more accomplished evolutionary biologist. Congratulations Naomi! 🍾

And the prize for best hairdo goes to…drumroll…this bumblebee-mimicking robber fly (Laphria spec.). This dude is such a close mimic it almost fooled me last weekend. These flies are fierce predators of other insects including, well, bees. Thorn Preserve, Woodstock, NY.

The spiny caterpillar of the Baltimore Checkerspot (Euphydryas phaeton). Named after Lord Baltimore, this species is the official insect of Maryland. Thorn Preserve, Woodstock, NY.

Here’s a large Dorylus molestus army ant worker guarding the trail of its colony at Mount Kenya.

Congratulations to our graduates! 🥳

Here’s a series of pictures from a Dorylus molestus army ant swarm raid at Mount Kenya. At a height of about 1.7 meters up the vegetation, the ants encountered a large slug. The slug initially responded to the ant attack by secreting and encapsulating itself in a thick layer of mucus. 1/3

The dogbane leaf beetle (Chrysochus auratus) is an absolute gem. As the name suggests, these beetles eat dogbane, and have adapted to tolerate the plant’s toxins. Thanks to Caroline Chaboo for confirming the ID. Woodstock, NY.

Immigrant pavement ants (Tetramorium immigrans) originally hail from Europe but are now common in North America. In the spring, they fight intense territorial battles with neighboring colonies. The first image is a portrait, and the second shows them butchering a caterpillar. Woodstock, NY.

Here are a few more portraits of the myrmecophilous clown beetle Haeterius brunneipennis, a guest of Formica wood ants. Thanks to Alexey Tishechkin for the species ID. Woodstock, NY.

Crematogaster acrobat ants have heart-shaped butts, undoubtedly the cutest in the ant world. As the name suggests, they are also very flexible, bending their derrière forward and over the head when upset. Here, they are taking care of their larvae. Woodstock, NY.

Here’s a massive rove beetle, the golden-brown Platydracus maculosus, up to ca. 3 cm in length. An actively hunting predator of other arthropods, this dude looked like an insect version of a Komodo dragon or a honey badger to me. Woodstock, NY.

The myrmecophilous clown beetle Haeterius lives inside the nests of Formica wood ants. I found this specimen in a mixed colony of Formica sanguinea-group slave-making ants and their Formica fusca-group hosts in my garden. The beetle is just under 2mm long. Woodstock, NY.

This time of year you’re likely to observe clumps of foam like the one shown here on all kinds of plants. This photo is from last weekend in Woodstock, NY. Ever wonder what these things are? (1/3)

Carpenter ant mating flights are imminent in New York. Here are two gynes (young, virgin queens) collected from their natal nests in Woodstock: The American carpenter ant (Camponotus americanus) and the ferruginous carpenter ant (Camponotus chromaiodes).

I’ve got this rock in my garden with both a carpenter ant (Camponotus americanus) and a wood ant (Formica fusca group) colony under it. Every time I flip it over all hell breaks loose and the ants start killing each other. Ants aren’t exactly the best example of love thy neighbor… Woodstock, NY.

A highlight from today’s walk at Onteora Lake in the Catskills with @pbrand.bsky.social and @tomaskay.bsky.social was this Eastern Copperhead (Agkistrodon contortrix), one of the few venomous snakes in New York. They are very well camouflaged and tend not to move, so are hard to spot.

Here’s another spectacle of New York spring entomology: Eastern tent caterpillars (Malacosoma americanum) are among the most social lepidopterans. In May, you can find their silken tents, in which they aggregate (and defecate).
