The parasitoid-host association between Orgyia antiqua (Linnaeus) (Lepidoptera: Lymantriidae) and Carcelia
atricosta Herting (Diptera: Tachinidae) is recorded here for the first time in Italy. A single caterpillar of O. antiqua was
collected in Northern Italy (Arzergrande, Padua, Veneto Region) in June 2015. After the specimen died, a single tachinid
larva emerged and pupariated. The emerged parasitoid was identified using DNA barcoding, with DNA extracted from the

Processionary moths belong to a group of about 100 species well known for their social behaviour and their urticating systems. The genus Thaumetopoea s.l. includes about 15 species and has been divided into three genera (Helianthocampa, Thaumetopoea s.s., and Traumatocampa) in the last revision, based on key morphological features of the adults and on the host plants of the larvae. We performed a total evidence approach to resolve the phylogeny of the genus Thaumetopoea s.l., analysing all valid taxa included in this group, plus a broad array of close relatives.
