A scanning electron micrograph zoom-in of a single wing scale from a pantry moth (Plodia interpunctella)—you know, the ones in your baking supplies.
Can't wait until somebody discovers how the underlying cell takes on such a wild shape & how the ECM is laid down.
Width of the image is ~8 microns.

As insect wings develop, they form "crumpled up" in a very particular way. Unlike origami, there are no crisp folds.
Then, at adulthood, the wings emerge and open up.
Here is a cricket hindwing that I prepped from a juvenile, compared to an adult wing (from Turchyn & Popadić, FEVO 2024) 🧪

Geometric order at multiple scales.
This is an optical slice into the eggshell of a fruit fly.
Every dot is the cross-section of a tiny pillar holding up the "roof" that is the outer surface of the egg. The black polygons are cavities left where cellular interfaces used to be. 🧪

You know those "veins" on the wings of insects? In some species, they join together with surprisingly complex mechanical linkages.
This is an electron micrograph we captured of a vein joint from a damselfly. Note how the cuticle spikes allow more flexibility in one direction than the other. 🧪

~Embryo gymnastics~
In some insect species, the developing embryo does half of a backwards somersault (a movement called "katatrepsis").
Kozo Miyakawa captured this process in a dragonfly in a 1987 paper w/ tons of pen & ink illustrations. 🧪

Nice! This is the first I've heard of him. Just found some of his amphipod drawings online. These are lovely.

The old descriptive embryology papers had some gems of hand-drawn illustration.
These are drawings of the developing embryo of a cabbage white butterfly (Pieris rapae), a species that is often an unwelcome muncher of your kale and bok choy plants.

Tardigrade eggs! 🧪
Some bizarre surfaces on these things. I'm trying (and failing) to imagine the cellular processes that give rise to the branched surface structures. Any ideas? Let me know.

Wings from a speckle-winged rangeland grasshopper (Arphia conspersa).
This specimen was collected by Wayne Schennum in CO in 1973, & then I recently imaged it at the Chicago Field Museum. Wayne passed away in 2021, leaving a wealth of notes & specimens that are still giving rise to new discoveries.
