About Euchlaena marginaria (Minot, 1869)
Euchlaena marginaria, commonly known as the ochre euchlaena moth, is a moth species belonging to the family Geometridae. This species was first formally described by Charles Sedgwick Minot in 1869. It is native to North America, where its recorded distribution ranges from south-central British Columbia and Idaho east to Nova Scotia, and south to Florida and Missouri. The wingspan of adult Euchlaena marginaria is approximately 40 mm. Adult moths are active from May to August each year; in the northern portion of the species' range, there is one generation per year, while southern parts of the range have two generations annually. The larvae of this moth feed on plants of the genera Alnus, Salix, Spiraea, Amelanchier, Viburnum, and the species Betula papyrifera. The larvae act as twig mimics, and have a mottled dark brown coloration.
