Abstract

We present a genome assembly from an individual female Lycaena helle (the Violet Copper; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The genome sequence is 547.31 megabases in span. The entirety of the genome sequence was assembled into 25 contiguous chromosomal pseudomolecules with no gaps, including the Z and W sex chromosomes. The mitochondrial genome has also been assembled and is 15.5 kilobases in length. Gene annotation of this assembly identified 20,122 protein coding genes.

Keywords: Lepidoptera; Lycaena helle; RNA-seq; Violet Copper; genome sequence.
