Morley’s Final Catalogue: Locally quite common on spruce-firs. Annually in my Ipswich garden to 1936 (Whit); Orford in July 1902 (Gbs); Leiston (Grey); Southwold, and plentiful among Scots-firs at Aldeburgh in 1892, also found at Flixton (Ctw). Brandon (Barrett); beaten freely from spruces at Barton Mills in early June 1916 (Elliott, Mly).
Recent Status: Less common than in Morley’s time.
Life Style: A single brooded species flying during June, July and August and coming to light. The larvae feed on Picea abies and P. sitchensis. The larvae hibernate. They pupate in a cocoon in the larval habitation or on the ground.
Identification: The smallest of the Epinotia species. The moth is not distinctively marked. It has a greyish or light brown wing with darker striations and three brown irregular transverse bands. The male has a costal fold. There is a similar rare E. nigricana but that male does not have a costal fold and the larvae feed on Abies alba. The larvae of E. nanana can be identified by their feeding habits. They initially mine a leaf and then move to an adjacent leaf using a silken tube. They feed on this leaf from the tube and deposit frass in the previously mined leaf. More Info
