49.268 [B&F: 1200a] Eucosma parvulana (Wilkinson, 1859)

 

Distribution and status 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 diminutive 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 Saw-wort in E. parvulana). In Hampshire known from Leckford and Botley Wood. Not recorded from the Isle of Wight since 1880. Wingspan 14-19 mm. On average smaller (although small specimens of hohenwartiana also occur), and the forewings are more uniformly coloured - strongly contrasted specimens are more likely to be hohenwartiana. No reliable distinguishing genitalic feature has been determined. Larva feeds within flowerheads of Saw-wort.
