49.318 [B&F: 1284] Dichrorampha vancouverana McDunnough, 1935

 

Notes: Local in dry grassland, rough meadows, downland and scrub throughout much of Britain, more numerous in the south. In Hampshire and on the Isle of Wight appears to be one of the species which is benefiting from the increase in average summer temperatures in recent years, with a marked increase apparent in the last ten years. Wingspan 10-16 mm. Often found during the afternoon and warm evenings flying around the foodplants. Distinguished from D. alpinana and D. flavidorsana by the sombre general coloration of the forewing, which is suffused with comparatively dull ochreous-orange and has a dull and inconspicuous medio-dorsal blotch [Bradley]. Larva feeds within roots of Yarrow and Tansy.
