Cydia splendana
Marbled Piercer

(Hübner, 1799)1260 / 49.341

Morley’s Final Catalogue: Common, feeding in acorns; unnoted in the west. Bentley Woods in July 1902 (Gbs); Glemham Magna (Bloomfield); Southwold in 1897 (Ctw); Sotterley in 1936 (Gd), Ipswich, Bealings, Foxhall; Flixton, Beccles, Fritton.

Recent Status: A very common species in Suffolk.

Life Style: A single brooded species that flies at night and comes to light during June, July, August and September. The larvae feed on the seeds of Quercus, Castanea and sometimes Jugulans. They leave the fruit when it falls to spin a cocoon in which to hibernate and then pupate. Larvae that are not fully grown at hibernation will return to the tree and recommence feeding to hibernate and pupate in the subsequent year.

Identification: The moth is a larger Cydia species. It is very variable. Colour varies through shades of white, cream, brown and grey with a darker basal area and terminal quarter. There are numerous darker transverse striae. Melanic variants are common. The clear distinguishing character is a prominent black or dark brown pre-ocellar wedge from the dorsum. The ocellus may have black marks and usually has plumbeous edging. The only confusion species is C. fagiglandana with the more uniform grey variants of C. splendana when the black wedge becomes the deciding character.
