Davey, P., 2009: A rare immigrant species that is resident in the Mediterranean and the north African regions and a transitory resident in central Europe, the larva feeding on the flowers and seedheads of carline thistle (Carlina vulgaris). In Dorset, the moth is a rare immigrant and transitory resident that tends to be recorded from the coast. A number of larvae were found on Portland on carline thistle in August 1999; this is the only instance of residency for the species to date, and, as there was no opportunity for immigration for any of the adults seen in 1983, 1998 and 1999, it may be that the moth is a more frequent transient resident than previously thought, particularly on unimproved grassland sites on Purbeck and on Portland where its foodplant is relatively common.
