Explanation of Names
PHLOGOSARIA: from the Greek "phlogos" (flame) or "phlogistos" (to burn or inflame) or "phlogosis" (inflammation) - a reference to the patches at the anal angle of the forewing and hindwing, which appear to be scorched or inflamed
wingspan approximately 27 mm.
adult: two color forms (representing subspecies?) - a darker reddish-brown form and a paler yellowish form; both forms usually have a diagnostic patch at the anal angle of the forewing and hindwing that gives the appearance of being scorched or inflamed
larva: gray with light brown and white speckling, with abdominal and thoracic humps, giving it the appearance of a short twig (U. of Alberta)
