Identification
The combination of small size (25–30 mm wingspan), pale coloration with fine wavy transverse , and association with deciduous woods helps distinguish this from similar . The single with extended period (April–September) is a useful phenological cue. Larval association with Cornus (dogwood) species provides additional diagnostic context where plants are known.
