Common NameOne-eyed Sphinx, Eyed Hawk-moth SeasonalityAdults have been collected in Alberta from late April to mid-August, an unusually long flight period IdentificationA large (6.2-9.0 cm wingspan) heavy-bodied sphinx moth. Forewings are pale grey (occasionally tan) with a rather complex pattern of darker grey and black banding. The median and terminal areas in particular are dark. Outer margin of the forewing is scalloped, with a "tooth" at the anal angle. The hindwings are bright rose-pink, shading into tan toward the margin. There is a large black spot in the anal angle containing a bright blue circle, often incomplete and sometimes with a second blue crescent above. Thorax is black, contrasting sharply with the broad pale grey tegulae. The very similar S. jamaicensis has two blue bars instead of a blue circle in the hindwing spot, and the pink is sharply divided from the tan outer part of the hindwing. Pectinations on the male antennae are also much shorter in cerisyi than in jamaicensis.

Life History One of the most common Alberta sphinx moths. The adults are nocturnal and come to lights. Larvae are solitary defoliators. The long flight period may indicate that there is more than one generation per year in Alberta. Conservation Common. Diet Info In Alberta, willow (Salix); elsewhere willows, poplars (Populus), pear and plum (Prunus), and snowberry (Symphoricarpos). Aspen poplar and willows appear to be the major hosts. Range Newfoundland west to Yukon and Vancouver Island, south to northern Mexico, including the Baja. A common moth, found in wooded or shrubby areas throughout Alberta.
