Yorkshire Status: Rare migrant.

This moth is so named because the wing markings resemble the Greek letters nu and iota. This takes a bit of imagination to see; the iota being more of a blob. It could be passed over for a small and rather ornate Silver Y by the unwary. It is a widespread species in the tropics but in Europe is a migrant. Our first record was at Spurn in 1982 and we have now had 12 records (up to the end of 2024), all in the south of the county except for one at Scarborough in 2024. There have been six records from Spurn. There were four records in 2011. Large influxes occasionally appear in the south of England. Many people have tried the pheromone lure for this species but all it seems to attract is Silver Y, or Dewick's Plusia if you are very lucky.

Sutton & Beaumont, 1989: This migrant species has now been recorded twice in the County. The first was at Spurn (VC61) on 17.7.1982 by B. R. Spence. The second was at Selby (VC64) on 16.9.1982 by S. M. Jackson.
