About Erannis tiliaria Harris, 1841
Erannis tiliaria, commonly called the linden looper, is also known by the ambiguous common name "winter moth". It is a moth species belonging to the family Geometridae. This species was first formally described by Thaddeus William Harris in 1841. It is distributed across North America, ranging from central Alberta eastward to Nova Scotia, and extending south to Missouri, Georgia, Utah, and Texas. For a period, Erannis vancouverensis was treated as a subspecies of Erannis tiliaria, but it is now recognized as a distinct separate species. Male linden looper moths have a wingspan between 32 and 42 millimeters, while females of this species are wingless. Adult males fly during late fall. The larvae of Erannis tiliaria feed on a variety of deciduous trees and shrubs, including basswood, apple, ash, beech, birch, elm, maple, oak, poplar, Prunus, and Ribes.
