We follow Laštůvka (1990) and consider the taxon venetensis Joannis, 1908 a synonym and not a separate subspecies. The taxon was erected for the most northern populations in France, which are, however, neither geographically isolated nor otherwise significantly different. Coloration and pattern of the type specimen is in the normal variation range of the species.
Barcodes. A homogenous species with minor differences in barcodes between specimens from the Iberian Peninsula and France.
Biology and habitat. The hostplant is Rumex acetosella. The relatively thin main root is usually completely destroyed by the activity of the larva and replaced by a silken tube in the empty root channel. Pupation takes place without cocoon in this tube. The moth is on the wing in May and June. The flight is slow and low in the immediate vicinity of the hostplant, often interrupted for resting in the vegetation or flower visiting. The latter has been observed in Corsica on Matricaria (Asteraceae), Globularia (Plantaginaceae) and Scabiosa (Caprifoliaceae). The species occurs in many different habitats with preference for sandy, schistous or volcanic soils, like beaches, dunes, stony slopes or rocks.
Distribution. South-western Europe, from the Iberian Peninsula, through southern and western France, northwards to the southern Bretagne, eastwards to Central and Southern Italy, including the Mediterranean islands Corsica, Sardinia and Sicily (Laštůvka & Laštůvka 1995, 2001, Špatenka et al. 1999).
