Cydia fagiglandana
Large Beech Piercer

(Zeller, 1841)1259 / 49.342

Morley’s Final Catalogue: Recorded from only Flixton near Bungay (Ctw), where it doubtless fed in the mast of planted beeches; and Fritton at light on 16 August 1934 (D).

Recent Status: Recorded across Suffolk.

Life Style: A single brooded species that flies at night and comes to light from May to September. The larvae feed inside Beech Masts. They may hibernate and pupate in a cocoon on the ground.

Identification: The moth is a larger Cydia species. It is similar to C. splendana. It has wings in shades of grey and white. The basal third is usually darker towards the dorsum and the ocellar area may also be edged darker but not as strongly black as in C. splendana. The wings show a more striated pattern that in C. splendana. It does not have the mellanic forms that C. splendana does. If necessary they can be separated by genitalia dissection. The larvae may fall to the ground with a Beech Mast before reaching maturity and feed from fallen masts. They may take two years to reach maturity. More Info
