It is also found in North America, from coast to coast across Canada and the northern United States to western Alaska. It occurs in the Rocky Mountains from Montana to southern Arizona and New Mexico. In the east, it ranges from Maine to North Carolina. It has recently been recorded in Tennessee.

GBIF citizen-science records
It is estimated from how often the Setaceous Hebrew Character is recorded against all the insects logged in Nizhny Novgorod (9 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.
