The combination of the rectangular forewing white spots, one long and one short, implies that this is a male.  The large spot on the female’s forewing is square.Note also the white below the antennal knobs, as Glassberg says for Little Glassywing.BUT white hyaline spots on FW is NOT a feature that distinguishes Little Glassywing from ALL other skippers
