Complete mitogenome data from a summer population specimen of the urticating pine defoliator (Lepidoptera, Notodontidae, Thaumetopoeinae, ).

We present a mitogenome assembly obtained from specimens sampled in the so-called summer population (SP) of (Denis and Schiffermüller, 1775) in Portugal. Contrary to the typical larval development occurring in winter in this species, the larvae of this unique population develop during summer. The sequencing data used were obtained from genomic libraries originally generated to assemble the nuclear genome of [1]. We also provide a complete annotation and a phylogenetic representation which positions the Portuguese summer population of and an Italian typical individual of the same species among the Notodontidae family and more distant Noctuoidea species. This data represents a valuable new resource for an expanding and urticating insect pest.
