This week we celebrated reaching 1000 lepidopteran genomes in the Tree of Life (ToL) programme @ the @sangerinstitute.bsky.social with butterfly crafts and cake! Many of these genomes were sequenced by the wonderful ToL teams as part of @projectpsyche.bsky.social & the Darwin Tree of Life project 🦋🧬
