Ethmia quadrillella, a smart-looking black and white micro-moth in the family Elachistidae (formerly in family Ethmiidae), was recorded by Peter Vernon at Colyford on 17th August 2012. This is a new county record for Devon – the species never having been recorded here before.
This moth is a scarce species (specifically listed as Nationally Scarce B) found as a resident mainly in eastern England from Kent up to Yorkshire, where it is typically found in wetland habitats. However, it is also known to occur as an occasional migrant or wanderer, so it is highly likely that this Devon individual had travelled either from eastern England or from Continental Europe. The sighting came during a period of considerable moth immigration.
