Form occidentalis Henry Edwards, Plate VII, Fig. 2, female. (The Western Poplar Sphinx.)

This noble hawkmoth feeds in the larval stage upon various species of the genus Populus and upon willows. There are a number of local races or subspecies, two of which we give; the common eastern form and the western variety. The latter may at once be distinguished by its generally paler coloration. It ranges over the United States and as far south as northern Mexico.
