πŸ’₯🧬 Why sequence ALL insect genomes?
Because insects run the planet. They pollinate our crops, recycle nutrients, build soils, drive food webs, and shape ecosystems on every continent. 🌍
Yet we’ve only scratched the surface of their genomic diversity.

Lino block portrait of aeronautical engineer Elsie MacGill shows her from the shoulders up wearing a suit and glasses with wavy short hair back, with a Hawker Hurricane above her and several tiny ones flying in front of her as well as a Maple Leaf Trainer II airplane by her head. The print is made in an ink gradient of green at the top, followed by gold in the middle and green again at the bottom on cream coloured Japanese washi paper, 9.25” x 12.5”, numbered, titled β€œElsie MacGill, Queen of the Hurricanes” and signed Ele Willoughby, 2025.

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:

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.

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.

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?

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.
