Identification
Distinguished from the similar Pachylia ficus (Greater Ficus Sphinx) by smaller overall size and more subdued wing patterning. Forewings are narrower with less prominent dark markings. Hindwings lack the strong contrasting bands seen in P. ficus. are relatively thicker compared to other Dilophonotini . Resting posture with wings held tent-like over the body, typical of the .

Distribution
Native to South America (Argentina, Brazil, Bolivia, Paraguay, Uruguay), Central America (Panama, Rica, Nicaragua, Honduras, Guatemala, Mexico), and the Caribbean. Documented in 27 Brazilian states. Vagrant individuals recorded in southern Texas and southeastern Wyoming, USA.
Seasonality
fly year-round in tropical portions of the range. Peak activity during wet season in areas with pronounced dry seasons. Northern strays appear primarily during late summer and fall (August–October).
