This species is often seen in May-August locally. Of the several specimens represented in our Pittsylvania County collection, all were captured as they perched near a nightlight at various gas stations.
On dark, humid summer nights (without moonlight) this species appears strange with its wings held in a deltoid configuration. When the moth was pinned in the collection box, its wings were spread in the flying position; the live specimen, perched near the gas station light is hardly recognized as the White-lined Sphinx. Collectors usually have well-trained eyes so as to recognize any unusual shapes that may be perched on walls. Nearly all rare moths in our local collection were collected after midnight when the flying moths seem to have settled.
