            White-lined Sphinx caterpillars can be extremely abundant;
            sometimes thousands are observed crawling on the ground in
            areas like the Arizona desert. The caterpillars are well adapted
            to a variety of habitats, being both polyphagous and also
            able to tolerate a remarkably wide range of temperatures—up
            to around 113°F (45°C)—changing their orientation on the
            host plant toward or away from a heat source to maintain a
            constant internal temperature. Mature larvae pupate in shallow
            burrows in the soil; adults eclose after two or three weeks and  y

            both by day and at dusk, hovering over  owers while drinking

            nectar. The species develops and breeds between February and
            November, producing two or more generations annually.


            Native Americans from the southwest United States consumed
            the caterpillars as food. In 1884, the entomologist William   The White-lined Sphinx caterpillar is often
