Kern primrose sphinx moth, euterpe sphinx moth
Euproserpinus euterpe is a small, day-flying sphinx moth endemic to California and federally listed as threatened. Adults are active from mid-January to early April, with peak activity in February and March. The species has a highly restricted, disjunct distribution limited to two known locations in Kern and San Luis Obispo counties. Larvae are specialized feeders on evening primrose (Camissonia species), while adults nectar on diverse regional wildflowers. Population abundance fluctuates dramatically with climatic conditions, particularly rainfall.
