The first rule of practical entomology is, you always underestimate how hard stuff is.* Anyone who's not daft in that way is wise enough not to get involved in the first place. 😎

Fossil taxa are sometimes considered island weirdos without any actual evidence that island effects were important in their evolution. So we wrote a paper on how we could do actual island biogeography in deep time. If you want a copy but can't access it, email me: www.nature.com/articles/s44...

What especially bothers me about science / natural history orgs using genAI to make LOGOS of all things is that a logo can literally be whatever you want. Draw a squiggle in paint right now and you're already good. A logo can be a single letter in TNR. There are no rules.

Music appears universally in human infancy with self-evident effects: as many parents know intuitively,
infants love to be sung to. The long-term effects of parental singing remain unclear, however. In an offsetdesign exploratory 10-week randomized trial conducted in 2023 (N = 110 families of infants, Mage =
3.67 months, 53% female, 73% White), the study manipulated the frequency of infant-directed singing
via a music enrichment intervention. Results, measured by smartphone-based ecological momentary
assessment (EMA), show that infant-directed singing causes general post-intervention improvements
to infant mood, but not to caregiver mood. The findings show the feasibility of longitudinal EMA
(retention: 92%; EMA response rate: 74%) of infants and the potential of longer-term and higherintensity music enrichment interventions to improve health in infancy.
Keywords: music, infancy, parenting, infant-directed song, ecological moment…the journal article version of the previous image

This is a wild assertion to make in the introduction to your 200-page treatise on paederine staphylinid trichobothria
“Matsuda (1970), in a dense, difficult to read, 400-page treatise on the evolution of the insect thorax, rejected the Ferris hypothesis after studying numerous species across the orders of Insecta” (the author is criticizing a seemingly crackpot theory about an internal structure of the beetle thorax)

Also in the carabid files: a strongly worded editorial by cave beetle expert Thomas C. Barr, a professor at the University of Kentucky. Dated Nov. 17, 1984.
“Creationist phoenix rises around election time,” an opinion essay by Tom Barr published in the Lexington Herald-Leader. He notes that creationist rhetoric always seems to flare up every time there’s a TN school board election.“The real question becomes: Can
we afford to teach teenagers the
twisted credo of a small, fundamentalist, anti-scientific sect as a substitute
for the best thought modern science has to offer?”“Can we afford to continue censoring biology textbooks so that evolution is not mentioned or is relegated to a brief, incomplete section in the back? Can we afford to hobble and harass science teachers by dictating that they cannot teach the greatest unifying theme in biology?
Mayor Scotty Baesler has said that businesses have been reluctant to relocate in Lexington because of "hor-ror stories about Kentucky schools.
Do we want to add another "horror" chapter?”

Today in the carabid section, a question we all must ask
Unit tray of many multi-mounted beetles (Oxypselaphus obscurus) with a large typewritten note from the previous collection manager (in what might have been his 1st or 2nd year on the job). The note reads “What the hell’s the story with these?” and notes that a bunch of specimens were mixed in with a similar North American species, despite the fact that they are exclusively palearctic

Once ubiquitous among Coast Salish communities, woolly dogs went extinct in the late 1800s. The only known pelt is now on display at the Museum of Anthropology in Coast Salish territory, more than two decades after it was discovered in a drawer at the Smithsonian.

After 167 years, this Salish woolly dog pelt has returned to B.C.
