Species Account

Sutton & Beaumont, 1989: This moth was first officially recorded in the County in 1983 when specimens taken in VC64 were dissected and found to be this species, however it has now been confirmed that specimens taken in VC65 had already been examined. All the Ear Moth species are probably much under-recorded in the County due to identification difficulties and this species may well have existed unnoticed in the County for many years.

2012 (CHF): All records are from VC64 and 65, mostly in the upland areas in the west. It is surprising that it has not been found in upland areas in the west of VC63, though Yorkshire is at the south-eastern edge of its range. The larval foodplant is probably yellow iris and the moth certainly does seem to be commonest in wetter areas where irises grow. The genitalia are very distinctive and unlikely to be confused with any other species. This is by far the commonest Ear at Malham where old Rothamsted records showed 1 Ear moth, 21 Large Ears and 189 Crinan Ears.
