We present a genome assembly from an individual female Grypus equiseti (Horsetail Weevil; Arthropoda; Insecta; Coleoptera; Erirhinidae). The genome sequence has a total length of 779.27 megabases. Most of the assembly (98.69%) is scaffolded into 12 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 19.25 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
Crowley et al. (2026) studied this question.
