The species was first described by William Barnes and Arthur Ward Lindsey in 1921.[4] It is found naturally in North America,[2] where it has been recorded throughout Arizona, New Mexico, and western Texas.[5] While some moths of its species have reportedly been photographed in California,[5]Meganola varia is not found on the California Moth Checklist.[6]
Its wingspan ranges from 26–32 millimeters.[4] Adults typically have dark gray or brownish gray coloration with a white speckling (irroration) that occurs as a result of the white tips on some its scales.[4][7] Adults have a flight period of June to October.[citation needed]
