The genome sequence of the Treble Brown Spot moth, Idaea trigeminata (Haworth, 1809) (Lepidoptera: Geometridae)

<ns5:p> We present a genome assembly from an individual male <ns5:italic>Idaea trigeminata</ns5:italic> (Treble Brown Spot; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence has a total length of 505.85 megabases. Most of the assembly (99.88%) is scaffolded into 27 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled, with a length of 16.49 kilobases. Gene annotation of this assembly on Ensembl identified 12 441 protein-coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces genomes for eukaryotic species found in Britain and Ireland. </ns5:p>
