A medium to large-size (4.5-6.0 cm wingspan) narrow-winged diurnal moth.

The hindwings are orange bordered with black. The body is light yellow-brown.
Juanita is another small colorful day-flying sphinx moth that may be found nectaring at flowers. Unlike most sphingid larvae, those of juanita lack an anal "horn". There is a single brood each year.
This is a rarely encountered species, at the northern edge of its range in Alberta
No Alberta data; elsewhere reported larval hosts include Evening Primrose (Oenothera sp.) and Willowherb (Epilobium sp.).
Juanita ranges from the grasslands of southern Manitoba, Saskatchewan and Alberta south across the Great Plains to northern Mexico. In Alberta, it has been collected in the Grasslands region, in the Lethbridge and Drumheller areas.
