The genome sequence of the Thor's Fritillary, <i>Boloria thore</i> (Hübner, 1803) (Lepidoptera: Nymphalidae)

We present a genome assembly from a female specimen of <i>Boloria thore</i> (Thor's Fritillary; Arthropoda; Insecta; Lepidoptera; Nymphalidae). The assembly contains two haplotypes with total lengths of 427.95 megabases and 366.63 megabases. Most of haplotype 1 (92.92%) is scaffolded into 31 chromosomal pseudomolecules, including the W and Z sex chromosomes. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 15.15 kilobases.
