Dichrorampha flavidorsana

Knaggs, 18671275 / 49.319

Morley’s Final Catalogue: Hemley in 1934 and bred from tansy at East Bergholt in 1931-4 (Whittingham).

Recent Status: A rare species in Suffolk.

Life Style: A single brooded species that flies from June till August and comes to light. The moth can also be found on the foodplant. The larvae feed on Tanecetum vulgare. They feed in the rootstock. They hibernate and pupate in the larval habitation.

Identification: Dichrorampha alpinana and D. flavidorsana are very similar. Only the males can be separated on characters of the adult moth with difficulty. The hindwings are brown and become slightly paler at the base for D. alpinana. In D. flavidorsana they are clearly paler at the base this being so for the females of both species. The costal fold of the male reaches to just over one third for D. alpinana and to between one third and one half for D. flavidorsana. Genitalia dissection is the only assured method of identifying these two species. Proximity of the foodplant is no guarantee of identification. More Info
