Common NameSpotted Buff Gem, Spotted Straw SeasonalityAdults are on the wing from May through September. IdentificationA medium-sized (3.3-3.7 cm wingspan) light yellow-brown or tan moth with darker markings. There is a broad darker brown median band crossing the forewing, which angles sharply inward at the lower end of the large blackish reniform, and a dark triangular patch near the apex. The hindwing is dirty white or very pale buff with a large dark thick discal crescent and a broad black terminal band with a pale, split spot at the anal angle. The very similar H. acesias has a yellowish (not buff) hindwing, less contrast on the forewing, and the forewing median band is not as sharply angled. There are also genitalic differences (see Hardwick, 1994). H. ononis is significantly smaller, less yellow and lacks most of the fine spotting on the forewing found in phloxiphagus. H. oregonica is smaller and darker.
