Classification
| Family: | Tortricidae |
| Subfamily: | Olethreutinae |
| Genus: | Eucosma |
| Species: | fulvana |
| Authority: | (Stephens, 1834) |
Distribution poorly known owing to confusion with hohenwartiana, it is likely that it will be found in dry open areas wherever the foodplant grows. Formerly regarded as a large, fulvous (i.e. dull brownish yellow) form of E. hohenwartiana, and distinguishable from this species with certainty only on the basis of the larval foodplant (Common Knapweed in E. hohenwartiana and Greater Knapweed in E. fulvana). In Hampshire fairly widespread in the south-east, with few records in the north or south-west. Not recorded from the Isle of Wight since 1900. Wingspan 19-25 mm. Distinguished by its large size and fulvous coloration, paler than hohenwartiana. No reliable distinguishing genitalic feature has been determined. Larva feeds within flowerheads of Greater Knapweed.
