White-lined Sphinx

Description:

Upperside of forewing is dark olive brown with paler brown along the costa and outer margin, a narrow tan band running from the wing tip to the base, and white streaks along the veins. Hindwing upperside is black with a reddish pink median band. Adults usually fly at dusk, during the night, and at dawn, but they will also fly during the day. Caterpillars pupate in shallow burrows in the ground. Massive population buildups occur which stimulate emigrations to colonize more northern areas.

Habitat:

A wide variety of open habitats including deserts, suburbs, and gardens.
