Here’s all the little cicadas together. Put a little varnish on them. Now I just need to cut them out, scan them, and get them in some frames.
4 small circular paintings of cicadas on a single sheet of paper.

NEW pub in @science.org 🥳

Is it sponges (panels A & B) or comb jellies (C & D) that root the animal tree of life?

For over 15 years, #phylogenomic studies have been divided.

Apropos of nothing in particular, here is a very small weevil posing majestically. (Brazil)

The black velvet is an optimal backdrop for these use cases, because even black paper or plastic tends to reflect a lot of light. Velvet is especially good for iridescent insects, IIRC it's what we used for these guys at DPI:

Histerid beetles are renowned for their extremely conserved (some would say 'boring', but we don't talk to those people) appearance. Here's a spicy one from French Guiana and Brazil - Phelister sanguinipennis.
dorsal photo of a point-mounted beetle. Beetle is elongate oval, rounded in front, kind of pointy in back. The head, thorax, and abdomen are dark reddish-brown, and the wing covers are a brightish red-orange. The head is projecting with two small fuzzy antennae at the sides, and the mandibles, while small, are pointy and slightly open.

And that's how you integrate digital elements into an exhibition. Part of the temporary "China's Dinosaur World" at the Shanghai Natural History Museum, China. Closing this November.

It is impossible not to love tiger beetles.

The Bronzed Tiger Beetles (Cicindela repanda) scampering along the Mississippi River beaches have subtle iridescent colors when you look closely.
A brown beetle stands on sand. There are white curly lines on the elytra scribbled in from the lateral margins. When you look closely at the brown parts of the elytra, thorax and head you see red and green iridescent sparkles

I've written a post about Cynomorium songaricum, a holoparasitic plant found in the deserts of Inner Mongolia. So how does this plant disperse its seeds across the desert and reach the roots of its hosts?

Well, with the help of some little friends. 🧪

#AncientRome Intaglio: Two #cicadas fighting as gladiators
Roman Republic, 1st c. BCE
Carnelian, 17 x 21 x 3.5 mm
“Rare subject referable to the late republican repertoire of #insects that perform human actions.”
www.invaluable.com/auction-lot/...
“The two insects fight vigorously using gladiators weapons. The cicada on the left protects itself with a shield and raises the sword to hit its opponent, who fights with a spear and a shield. Both insects are finely engraved in detail, with the use of the typical mirror-polished globular elements. Groundline. Traces of letters in the field, partly erased due to the ancient wear marks of the stone surface. Attractive size and color of the stone. Slight crack in the lower left corner of the stone. Rare subject referable to the late republican repertoire of insects that perform human actions.”

Quote from the Figure 1 heading in the paper: "Figure 1. Range map for Uranotaenia sapphirina. Shaded range is approximate and is drawn from the literature: Mexico, after Ortega-Morales et al. (Reference Ortega-Morales, Rodríguez-Martínez, Méndez-Alvarado, Garza-Hernández, López-Hernández and Medrano-Santillana2022); United States of America and Canada, after Darsie and Ward (Reference Darsie and Ward2005). The dot is 2022 New Maryland, New Brunswick collection; the Xes are our 2023–2024 collections near Woodstock, Fredericton, St. Martin’s, and Sussex, New Brunswick. The square is Stuart’s (Reference Stuart2007) record from Winnipeg, Manitoba; stars are selected research-grade observations from iNaturalist. The province of New Brunswick is enlarged, showing collection localities."

I don't like rules about the use of common names in biology. The entire point of common names is that they ebb and flow and change and adapt to local needs. You can make them up. You can let different cultures have their own names.

Save the rules for the scientific names.

Remembering the time I threw a geology-paleontology themed Bday party for the kids. Filled a kiddie pool with sand, real fossils & rocks, then had the kids dig & ID their finds for Geo-Paleo Bingo. Ended by exploding a giant Coke & Mentos volcano at the dig site. 😅 #AcademicParents

A Geo-Paleo-BINGO card with boxes for Fossil Dinosaur Bone Gypsum Rosettes Apatite Rose Quartz Pyrite Brachiopod Fossil Jasper/Agate Arrowhead (yes one archaeology find, & I did explain differences btwn geology, paleontology, & archaeology to kids) Ammonite Fossil Pumice Dig Into Rocks & Fossils pocket booklets for kids to ID their finds (they got to keep the booklets & finds)

A recent @newscientist.com cartoon #fungi
Panel One: A scientist is giving a lecture. she stands at a lecturn. The current slide shows a list of the five kingdoms of living things: Animalia, Plantae, Fungi, Protista and Monera. She says "Most people assume that fungi are plants. Whereas in fact, they form a kingdom of their own." Panbel Two: Caption : After the lecture The scientist now appears to be in a subterranean cave, before her stand two very large mushrooms guarding a larger, beardedmushroom who sits in athrone wearing a crown. One of the mushrooms says "His majesty is very pleased with the work you are doing."
