65.004 [B&F: 1649] Dusky Hook-tip (Drepana curvatula) (Borkhausen, 1790)

 

Notes: Rare immigrant from mainland Europe, appearing in southern and eastern England. First recorded at Dungeness, Kent, in August 1960. In Hampshire the UK's fifth record was discovered at Totton in August 1991. Recorded on the Isle of Wight for the first time at Freshwater in 2002. Wingspan male 37-40 mm, female 40-49 mm. Can easily be overlooked as a dark Pebble Hook-tip D. falcataria, but in that species the outer discal spot on the forewing is much larger than the other two, and on the hindwing the cross-lines in Pebble Hook-tip are more jagged and the wing is noticeably paler towards the costa (MBGBI Vol 7 part 2). Larva feeds on Silver Birch, Downy Birch, Alder and Oak, no evidence of breeding in the UK.
