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 Baltimore on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 400th most-seen of the 705 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.
August
In that month about 10% of wildlife watchers report a Hops Angleshade in Baltimore on a given day, against under 5% in September to July, the lowest months.

GBIF citizen-science records
It is estimated from how often the Hops Angleshade is recorded against all the insects logged in Baltimore (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.
