The complete genome sequence of Apodemia mormo langei, Lange's Metalmark Butterfly

A complete genome assembly for the endangered Apodemia mormo langei (Lange's Metalmark Butterfly) (Comstock, J.A. 1938) is reported here. Illumina short-read sequencing was performed using tissue from a single deceased individual. The selected specimen was a foundress individual collected directly from the wild population prior to captive propagation, minimizing the potential influence of captive breeding, genetic drift, or artificial selection on genomic patterns. This reference genome is an important resource for studying this presumably extinct dune-endemic butterfly.
