Historically, this species was known from Alaska to California and northern Mexico, east to New Mexico, and north to Manitoba. Recent sightings across the northern US and eastern Canada may indicate colonization of new territory by the species. The earliest record from the east that could be located online is from NS in 2012. This record was followed by single sightings in 2013 and 2014 in WI, one in MA in 2017, and a few in NY over the last few years. There are a dozen records of the species in the eastern US and Canada in 2019 on citizen science websites. The species is known on Block Island from a single specimen collected at AH August 7, 2019.
