Hemileuca e. eglanterina.
The Western sheepmoth (wingspan: m: 57-70mm; f: 57-72mm), is highly variable in its colouration and patterning. Forewing upperside ground colour ranges
from yellow-orange to cream to pink with black markings. The upperside of the hindwing is yellow-orange to orange with narrow to wide black markings.

Hemileuca hera.
Hemileuca hera, (wingspan: m: 55-67mm; f: 62-64mm), flies in the Great Basin area of southeastern British Columbia across southern Alberta to
central southern Saskatchewan in
sagebrush communities, pinyon-juniper woodland, and subalpine sagebrush meadows at elevations as high as 10,000 feet.
Wings are white with black markings including a black crescent-shaped cell spot on each wing. only in southern Alberta

Hyalophora cecropia male.
Cecropia (m: 120-145mm; f: 130-150mm). Males and females both come to lights. There is considerable variation
in the width of the red lines from specimen to specimen. Occasionally the forewing crescents are absent or greatly reduced.

Hyalophora c. gloveri male. In Canadian Prairie provinces
this is a reddish-brown species with maroon to burgundy highlights in basal and median areas. The post median area tends to
be grey. The white cell markings are not elongated as most often occurs in the hindwings of euryalus.
extensive range in Alberta. Sometimes quite bright.

Hyalophora kasloensis male. Hyalophora "kasloensis" is believed to have originated
as a hybridization between H. euryalus to the south and west and Hyalophora columbia to the east and north. It is self-sustaining.
Moths tend to be darker than euryalus with more black scaling in the sub-terminal and terminal areas.
The larvae have bright red thoracic and abdominal scoli. extensive range in western Alberta
