Davey, P., 2009: A local and declining species with a scattered distribution across Britain, the larva feeding nocturnally on cock's-foot (Dactylus glomerata), common couch (Elytrigia repens) and reed canary grass (Phalaris arundinacea). The adult is thought to aestivate between late-July and mid-August. In Dorset, the moth used to be frequent very locally within two markedly different bioptypes, heathland and chalky grassland, but has declined to the point of extinction over the past thirty years. The last record was from the far north-east of the county: Scrubbity Barrows, at MV light on 15 July 1997 (P Davey). "This distribution is curious. It is to be noted that whilst not by any means uncommon in the heath and pine area of the south-east of the county, it is well represented in the cretaceous of Purbeck and abundant in the cretaceous of the north-east of the county." (W Parkinson Curtis ms). There is no evidence of immigration to Dorset. There may have been some confusion on the naming of this species in the past as Tutt persisted in identifying orbona (Hufn.) as equalling comes (Hubn.); whether this fact impacts the validity of some of older records is unknown. Continued monitoring for this species in Chase Woods is recommended.
