dark individuals are easily confused with the similar Hypena decorata which appears to have an indistinct orbicular spot or blob that almost touches the AM line, and a black line running from the reniform spot part-way to the AM line (compare images of both species at CBIF, and see photo of H. decorata H. decorata has a flight season of late February to late September in California

Hypena modestoides has a pale band beyond the PM line, and its PM line is more oblique, with a large tooth near the inner margin (compare images of both species at CBIF)
