Dichrorampha sedatana
Dingy Drill
Wingspan around 14 mm. This species requires identification by genitalia dissection – it resembles Dichrorampha plumbana but is generally slightly larger, and has a yellowish suffusion around the base of the forewing not present in that species.
It inhabits rough ground, verges and embankments etc. where Tansy, the larval foodplant grows.
Adults fly in April and May. The male flies actively during hot sunny weather but the female usually remains at rest on the Tansy plants; both sexes fly at dusk.
The larvae feed in the roots of Tansy (Tanacetum vulgare).
In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as Nationally Scarce B.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
