Lifecycle NotesLarvae are slender, brownish 'loopers' that feed on various low-growing herbaceous plants. They typically overwinter as larvae and pupate in a loose cocoon near the ground.
Identification TipsKey features include the relatively uniform dark brown coloration with a purplish sheen on the outer wings, and the typical triangular resting posture. The lack of strong, contrasting patterns helps distinguish it from many other geometrid moths.
Description
