ws: 38-42mm; Sep; box (Buxus spp); accidental import with box plants. First British record 2008. Status uncertain - but probably now established in SE.England
Cydalima perspectalis §1 male
ID: Unmistakeable amongst British species, in both the bordered and dark forms.
Having said that there are 19th century records of a Diaphania species, originally identified as Diaphania hyalinata (C&S.America) (which is illustrated in Goater), subsequently reidentified as Diaphania indica (Asia), both of which appear very similar to the bordered form of C.perspectalis except that in the Diaphania species the dark border involves the thorax and the anal tuft is a paler brown.
