Herpetogramma pertextalis, commonly known as the bold-feathered grass moth, is a species of moth of the family Crambidae. It was first described by Julius Lederer in 1863 and is found in North America.[1]
Adult bold-feathered grass moths have a wingspan of about 33 mm and hold their wings open at rest, exposing both the forewings and hindwings. All four wings are whitish-tan and iridescent with a series of jagged lines. A dark brown line is present at the lowermost margin of all four wings[2] https://bugguide.net/node/view/42586.
This species is native to North America and is most commonly observed in open grassy areas such as fields, lawns and pastures.[3] [4]
H. pertextalis larvae feed on the leaves of Clethra alnifolia.[5]
