What characteristic defines the Order Lepidoptera for the adult *Operophtera brumata*?
Answer
Universally recognized by their scaled wings, which are modified, flattened hairs
The placement of the Winter Moth into the Order Lepidoptera is directly related to a distinctive feature shared by all moths and butterflies: scaled wings. The term Lepidoptera itself translates to 'scale wing.' These scales are not typical hairs but are flattened, modified structures that cover the wings and body. These scales are crucial as they impart the organism's color and pattern and can also influence aerodynamic properties during flight. Even though the female *O. brumata* is nearly wingless, the classification relies on the structure present in the male moth, which possesses light tan, fringed wings covered in these characteristic scales.
