Norfolk status
Unknown - Newly Recognised in Britain.

Resent research including examination of DNA bar codes has showed that there are two species amongst what were known as Phalonidia manniana.

Slight differences occur in appearance (see P. manniana) however these are extremely hard to define, and they can only be reliably determined by gen. det. P. udana is also slightly larger than P. manniana. (see comparison plate)

They also have different foodplants, P. manniana feeding as a larva on Water Mint and Gypsywort, P. udana feeding on Loosestrife.

Distribution in Britain is unknown until many more specimens have been correctly identified.

First published Norfolk specimen from Hickling in 2010. (D. Agassiz, 12/07/10). Recent research from small samples suggest the species seems confined to the Norfolk Broads with just one recorded away from here at Aldeby Carr along the Waveney Valley in 2014. Any specimens suspected of being this species must be retained. [Ent. Rec. 125 p150 (2013)]

New for West Norfolk in 2019 when a male moth was trapped at Titchwell, confirmed by Gen. Det. R. Terry (D. Howdon, A. Culshaw, 01/06/19)
