Niphonyx is a monotypic genus of moths in the family Noctuidae erected by Shigero Sugi in 1982. Its only species, Niphonyx segregata, the hops angleshade, was first described by Arthur Gardiner Butler in 1878. It is endemic to eastern Asia, including the Russian Far East, the Korean Peninsula, Japan, China and Taiwan. It was introduced to the north-eastern United States in the 1990s and is found from Connecticut south to at least Delaware.
The wingspan is 25–30 mm. There are two generations per year in North America. The larvae feed on hop species. Wikipedia →

Rare
Under 5% of wildlife watchers report a Hops Angleshade sighting in Washington on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 1188th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Hops Angleshade in Washington on a given day, so our monthly data shows no clear season.
5th of 5
Of the 5 cities where we can rate Hops Angleshade sightings, Washington ranks 5th at under 5%. The best odds are in Seoul (South Korea, about 10%), Beijing (China, under 5%) and Baltimore (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Hops Angleshade that you can see in Washington (family Noctuidae, Cutworm Moths and Allies) are American Dagger (about 10%), American Copper Underwing (about 10%) and Smeared Dagger (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hops Angleshade is recorded against all the insects logged in Washington (10 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
