Dichrorampha flavidorsana

Knaggs, 1867


Wingspan c. 14 mm.

A very similar species to D. alpinana, the present species having a narrower dorsal blotch among other subtle differences, it is however best to refer to the structure of the genitalia for confirmation.

Most Dichrorampha species feed on the roots of various related plants, and flavidorsana is no exception, the larvae feeding in the rootstocks of tansy (Tanacetum vulgare).

June and July is the flight period for the adults, which can be seen in the afternoon, but generally flies after dark.
