The genome sequence of Zethes insularis Rambur, 1833 (Lepidoptera: Erebidae)

We present a genome assembly from a male specimen of <i>Zethes insularis</i> (Arthropoda; Insecta; Lepidoptera; Erebidae). The assembly contains two haplotypes with total lengths of 862.07 megabases and 869.20 megabases. Most of haplotype 1 (99.0%) is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. Most of haplotype 2 (95.76%) is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled, with a length of 15.77 kilobases. This work is part of Project Psyche, a collaborative programme generating genomes for European butterflies and moths.
