The Big Poplar Sphinx (''Pachysphinx occidentalis'') is a moth of the Sphingidae family. It lives throughout Canada and the United States. The habitat consists of riparian areas and suburbs. The wingspan is 130–150 mm. There are two color forms, a pale form with yellow brown forewings, which are dark gray in the dark form. The lines and bands are well-defined. The upperside of the hindwing has a crimson patch covering varying amounts of the wing, and two dark lines which do not form a distinct triangle. There are two generations per year in southern Arizona with adults on wing from May to September. Farther north, there is one generation per year with adults on wing from June to August. The larvae feed on cottonwood ''Populus'' and ''Salix'' species. ==Subspecies== *''Pachysphinx occidentalis occidentalis'' (from Alberta and North Dakota west to eastern Washington, south to Texas, Arizona, southern California, and Baja California Norte) *''Pachysphinx occidentalis regalis'' Rothschild & Jordan, 1903 (Mexico) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pachysphinx occidentalis」の詳細全文を読む スポンサード リンク
