An incredibly rare immigrant moth, the Shining Marbled Pseudeustrotia candidula, only once seen in Britain before 2012 was caught by Allan Jenkins at Chardstock, north of Axminster on 18th August 2012. The specimen is shown below.
This is the first time that the Shining Marbled has ever been recorded in Devon.
The moth, which is native to central and eastern Europe, was first seen in Britain in 2006 in Herefordshire. There have been no other records until this year, when a handful of Shining Marbleds have been sighted across southern England (including the Devon example). Although the moth was caught in August, this highly significant record has only recently been reported to Devon Moth Group.
An extremely rare immigrant moth, Diplopseustis perieresalis, was found by Andrew Cunningham in his garden at Tiverton on Sunday night (2 Sept 2012). It is thought to be only the 17th ever record for Britain, the second ever for Devon and is a new species for North Devon (Vice-county 4).

This pyralid moth is found widely across eastern asia, Australia and New Zealand, where it is thought that the larvae feed on rushes. In western Europe, the first sighting was in the year 2000 in Portugal, and the species has first occured in the UK (on the Isles of Scilly) in 2001. Further British sightings followed. The first mainland record was from Exeter, when Graham and Jean Jarvis found one in their garden trap in November 2007.
It is not clear how this moth managed to spread from the far east to western Europe, but it seems that it is established somewhere in the region and further immigration into Britain is likely in the future.
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.
