Wingspan 13 - 15mm. The fore-wings are dark brown with a broad yellow blotch across the centres. Very similar to D. flavidorsana, which has a slightly narrower yellow blotch.
Meadows, rough ground grassy areas where ox-eye daisy grows, the food-plant of the caterpillars. D. flavidorsana feeds on the roots of tansy.
