Black-banded
Polymixis xanthomista
This moth was only 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. Also recorded in 2007 from one site on the Lleyn
Peninsula but still unknown elsewhere. There are many other similar coastal
sites where the moth may yet be found if anyone ever chooses to look for it.
Chalk Carpet
Scotpteryx bipunctaria cretata
Recorded recently from the Great Orme. Also known from limestone areas of Denbighshire.
Double Line
Mythimna turca
The fact that there are numerous recent records as compared to rather few older
ones suggests that this moth may be becoming more common.

Netted Carpet
Eustroma reticulatum
Thought to be extinct. Recent larval records are considered erroneous and it
is possible that the moth has not occurred in North Wales in historic times.
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 the Great Orme.Square-spotted Clay
Xestia rhomboidea
Known from one site in Montgomeryshire where it appears to be common. This moth
must surely occur elsewhere in North Wales?
Sword-grass
Xylena exsoleta
No recent records. The species has declined generally in Britain for unknown reasons.
Waved Carpet

White-spotted Sable Anania funebris
Very scarce in North Wales - only recorded at two sites in the last thirty years. The decline is for the usual reasons of agricultural improvements and increased sheep numbers.
