Northwest Territories, Canada
Five Sphingidae species are listed for
Northwest Territories, based on an intial list provided to me by David
Tilden. I have added two species with no confirmed reports.
Please help me develop this list with improved, documented accuracy
by sending sightings (species, date, location), preferably with an
electronic image, via email to
This page is dedicated to David Tilden and
Tom Andrews who have sent data and/or images for the Northwest Territories.
the Canadian Sphinx or
Clemen's Sphinx. In both sexes, the dark border on the outer margin
widens as it approaches the inner margin. The upperside of the
hindwing is deep yellow in males,
pale yellow in females; both with a wide black border.
Sphinx canadensis, the Canadian Sphinx, is not common, and is not
often reported anywhere,
but it might be present in Northwest Territories.
Larval hosts are white ash (Fraxinus americana) and blueberry
(Vaccinium). maybe ??
DT, the Poecila Sphinx.
The forewing is dark gray with diffuse black and gray wavy lines with
a series of black dashes ending at the wing tip, and a white cell
spot. The white cell spot readily distinguishes poecila from
the Cerisyi's Sphinx

provinces and in northern border states. The one-eyed sphinx is also
found along the U.S. west coast, eastward to the Rockies. At my home

Hemaris thysbe moth for a small hummingbird as it hovers,
sipping nectar from flowers through a long feeding tube.
DT, the Bedstraw Hawk Moth
or Gallium Sphinx
This species is reported in Northwest Teritories.

it may not be common. Look for them in meadows near coniferous
