Phaeton primrose sphinx moth, Phaeton Primrose Sphinx
Euproserpinus phaeton is a medium-sized sphinx moth (Sphingidae) native to arid regions of southwestern North America. Adults are diurnal nectar-feeders, flying rapidly close to ground level over desert washes and flats during early spring. The species has a single annual generation and is dependent on Onagraceae plants for larval development. Its restricted activity period and specific habitat requirements make it a notable component of spring desert ecosystems.
