How do the wings of *E. sarcitrella* appear when the moth is perched?
Answer
Held tent-like over the body
The way an adult moth holds its wings while resting significantly affects its visual presentation and aids in identification. When *E. sarcitrella* is perched, its wings are typically held in a configuration described as tent-like over the body. This posture influences how the pattern of the forewings is perceived. Furthermore, this specific resting stance often serves to expose that characteristic pale shoulder area on the thorax, which helps distinguish it from other species that might fold their wings differently or hold them flatter. This roof-like positioning, combined with the wing markings, forms a crucial part of its typical resting silhouette.
