Black-banded     Polymixis xanthomista
This moth was only recently added to the North Wales list after it was discovered in 1999, as a result of targeted light trapping at a rocky coastal location in northwest Anglesey. Now known from two locations but apparently absent from many other sites that look suitable.

Chalk Carpet     Scotpteryx bipunctaria cretata
Recorded recently from the Great Orme. Also known from limestone areas of Denbighshire.

Double Line     Mythimna turca
No recent records in our region although this may be due to a lack of survey effort. In South Wales the species has been found at a number of new sites in recent years.

Narrow-bordered Bee Hawk-moth     Hemaris tityus

Netted Carpet     Eustroma reticulatum
It had been feared that this species was extinct in North Wales but in September 2003 it was announced that larvae had been found at a location in Merionethshire. The only other colonies in Britain are in the Lake District.

Orange Upperwing     Jodia croceago
Possibly extinct in Britain. The last sightings were in Cardiganshire, mid Wales so if the species still persists anywhere it could possibly be in North Wales. There are many oak woods in our region where no one has ever set a light trap, especially late in the autumn or early in spring as would be necessary to catch this moth.

Pale Shining Brown     Polia bombycina
This moth has not been seen in North Wales for many years and in fact is now considered to be one of the most seriously threatened moths in Britain.

Silky Wave     Idaea dilutaria
There are only three localities in Britain where this moth can be found, one of which is on the Great Orme.

Square-spotted Clay     Xestia rhomboidea
Although there are old records for this species in North Wales it is by no means certain that they are reliable.

Sword-grass     Xylena exsoleta
No recent records. The species has declined generally in Britain for unknown reasons.

White-spotted Pinion     Cosmia diffinis
There are no recent records for this moth and the past status is unclear.
