The flowers are 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, [10] orange (sometimes blood orange or rarely yellow) with a three-lobed corolla; one of the calyx lobes is colored similarly to the corolla and forms a hooked conical spur at the back of the flower. Plants may also produce non-showy cleistogamous flowers, which do not require cross ...
Their data also showed that the annual presence of H. lineata populations selects for whiter flowers. Other hawk moth species with similar range overlap, specifically Sphinx vashti, show a correlation of annual presence with longer spurs on flowers. Thus hawk moths in general have been demonstrated to impact selection on flower morphology. [10]
Its long proboscis (25–28 mm (1.0–1.1 in)) [9] and its hovering behavior, accompanied by an audible humming noise, make it look remarkably like a hummingbird while feeding on flowers. Like hummingbirds, it feeds on flowers which have tube-shaped corollae. [9] It should not be confused with the moths called hummingbird moths in North America ...
