Main: (Nepticulidae / Nepticulinae)
04.096 [B&F: 0030] Ectoedemia arcuatella (Herrich-Schäffer, 1855)

 

Notes: Nationally scarce (Na) on chalk downland and scrubland in southern and northern England, but absent from the Midlands. Very rarely recorded in Hampshire, where known from just a handful of sites. Not recorded from the Isle of Wight to date. Wingspan male 4.0-4.9 mm, female 3.6-5.2 mm. The imago is very similar to E. atricollis, from which distinguished by its smaller size, the more direct and more central fascia, and the paler apical cilia bounded inwardly by the dark line curving well round the apex (MBGBI Vol 1), although in most cases only separable with certainty by dissection of the genitalia; females difficult to separate from Ectoedemia spinosella. Adults difficult to distinguish from other Ectoedemia species, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Wild Strawberry and Barren Strawberry, over-wintering as a pupa.
