73.133 [B&F: 2356] Scarce Arches (Fabula zollikoferi) (Freyer, [1836])


Rare immigrant, probably from as far east as the Ukraine or the Ural Mountains, which has appeared in eastern Britain from Kent and Sussex northwards to Angus, most records having occurred during the month of September. Just two of the 17 records (to 2018) have been since the second world war, the most recent from Sussex in 1996. September 1934 was exceptional with eight records, with no other year having more than a singleton. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 42-52 mm. Bulrush Wainscot Nonagria typhae has some resemblance to darker forms of Scarce Arches, but has the forewing with termen more oblique, the median area speckled, the reniform stigma indistinct, and the fringe chequered (MBGBI Vol 10). Larva feeds on Common Meadow-rue, Lesser Meadow-rue and Great Fen-sedge, no evidence of breeding in the UK.
