Description edit

The wingspan is 17–25 mm.[2] The moths fly from dusk, in two overlapping generations from March to October, depending on location.[3] They are also attracted to light.[2]

Early stages

The larvae feed on devil's-bit scabious (Succisa pratensis), common toadflax (Linaria vulgaris), weasel's snout (Misopates orontium), small scabious (Scabiosa columbaria) and widow flower (Knautia species). There are differences in the early and intermediate larval instars which may be two different species or the variation may be due to diet, season or normal variation within the species. Larvae found on one foodplant can be reared on the other foodplant. They overwinter as an early instar. Spring generation larvae feed within a stem and some, later in a folded leaf, while the summer generation feed in the flowers.[2]

Pupae are attached to the larval foodplant or to a nearby stem.[2]

Distribution edit

The twin-spot plume is found in Europe, Asia Minor, Syria, North Africa and Iran.[4]
