In North America it is found across northern [[Canada]] from [[Quebec]] to western [[Alaska]], south to the northern parts of the [[United States]], and in the mountains to [[Colorado]]. It is also found in [[Greenland]], the coastal areas of [[Scandinavia]] and the [[Ural (region)|Ural]]. It was recently recorded from [[Denmark]], although this includes ''[[Euxoa lidia]]'', which some authors regard to be a valid species.
The [[wingspan]] is {{Convert|34|–|40|mm|abbr=on}}. Adults are on wing from June to August in North America and from July to August in northern Europe. There is one generation per year.
The larvae feed on ''[[Taraxacum]]'' and ''[[Polygonum]]'' species.
