The genome sequence of the Tansy Beetle, <i>Chrysolina graminis</i> (Linnaeus, 1758)

We present a genome assembly from a female specimen of <i>Chrysolina graminis</i> (Tansy Beetle; Arthropoda; Insecta; Coleoptera; Chrysomelidae). The assembly contains two haplotypes with total lengths of 1,467.20 megabases and 1,455.42 megabases. Most of haplotype 1 (98.03%) is scaffolded into 12 chromosomal pseudomolecules, including the X sex chromosome. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 17.07 kilobases.
