49.316 [B&F: 1278] Dichrorampha sequana (Hübner, [1799])

 

Notes: Local in dry pastures, gardens, orchards, parks and waste ground throughout southern England and south Wales. In Hampshire fairly widespread, and perhaps under-recorded due to its day-flying habits, but not recorded on the Isle of Wight for many years; apparently readily colonises areas where Yarrow is allowed to thrive. Wingspan 9-11 mm. Day-flying in afternoon sunshine. Recognised by the conspicuous, vertical, cream-white rectangular medio-dorsal blotch of the forewing [Bradley]. Larva feeds within roots of Tansy and Yarrow.
