Hospodářská, @petrnguyen.bsky.social et al. investigated genome size and karyotype in Polyommatus and Lysandra butterflies, rejecting polyploidy to confirm karyotypic diversification via chromosome fragmentation in Polyommatinae butterflies.

To celebrate the genomes for 1,000 (!) species of Lepidoptera in Europe, Project Psyche has released a preprint outlining our ambitions to jointly sequence & leverage genomes of all 11,000 species in Europe to propel science, conservation & society.

This was a joy to write together as a community!

Project Psyche @projectpsyche.bsky.social · 25d

(6/6)📄 In our new whitepaper (EcoEvoRxiv) we discuss our aims to coordinate this collaborative analysis of Lepidoptera genomes, turning data into impact for science, conservation and society.

(1/6) 🦋 We are thrilled to announce the release of the 1,000th reference genome of Lepidoptera species found in Europe!
This goal was reached with the release of Stenoptilia islandicus, also known as the mountain plume moth.
Read the story below!👇🏽

Genome sequencing progress for Lepidoptera.
Stacked bar charts represent the cumulative number of lepidopteran species with a reference genome per year. The colours represent the different levels of genome assembly quality, ranging from contig to chromosome-level. Numbers in brackets represent the range in numbers of species that have a given assembly level per year. Data derived from GoaT on 05.09.2025.

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.

Constraints on chromosome evolution revealed by the 229 chromosome pairs of the Atlas blue butterfly

The genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...

We never imagined our scientific articles would be displayed in an art museum!

Thanks so much, Lucas, for the joint experiences in Kenya, following the migrating butterflies, and in The Hague, admiring the outcome of your work!

Being invited to the opening of the photo exhibition Constant Bloom in Fotomuseum Den Haag was a privilege. The author, Lucas Foglia, followed the migration of Vanessa cardui across 17 countries to show how this butterfly connects societies, an art project that won the 2024 Guggenheim Fellowship.

The disguise is completed by chemical mimicry: the surface chemical hydrocarbons are identical to those of the termites. See the discovery and analyses published in @CurrentBiology Blow fly larvae socially integrate termite nests through morphological and chemical mimicry

The false eyes are the spiracles through which it breathes. The body is surrounded by “tentacles” that imitate the termite antennas, so that it can communicate with multiple termites simultaneously.

It’s not the head, it’s the butt!
Meet a completely unknown organism: a blow fly (Calliphoridae) that evolved social integration in termite nests using a false termite head in the posterior part of the body.
