Hyles euphorbiae, Johnson County, Wyoming,
June 24, 1012, courtesy of Edna Woodward.
Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an
image, via email to Bill Oehlke.
I do not have confirmed reports of all of these species in Johnson County, but I (WO) expect they are present.
This page is inspired by and dedicated to Edna Woodward who sent me the beautiful image of Hyles euphorbiae, top of page.
Edan has sent beautiful images from many of the western states.
Please also send your sightings to BAMONA, an excellent on-line resource. As of June 25, 2012,
no Sphingidae species are confirmed by BAMONA as flying in Johnson County. I am sure there are many species there which simply have not been reported.

the Waved Sphinx:
The upperside of the forewing is pale brownish gray with wavy black and white lines and a black-outlined white cell spot.
The upperside of the hindwing is gray with diffuse darker bands. possibility, generally more southerly in Wyoming.
The costal area in the basal and median areas of the forewing is light grey. This colour also
appears in the terminal area. The rest of the wing is dark slatey grey.
the Canadian Sphinx or
The upperside of the forewing is yellowish gray in males and pale gray with a faint yellow tint in females. 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.
The upperside of the forewing has a narrow black subterminal line
bordered by a white inverted V-shaped line on the outside, and a
black line running inwards from the apex of the wing.
It is most often found in montane woodlands and along streamcourses.
the Modest Sphinx or Poplar Sphinx.
The forewing is grey brown with diffuse lines.
The hindwing is bergundy with dark blue to black markings near the anal angle.
This one is quite similar to Pachysphinx modesta, with modesta
being smaller and darker.
Forewing lines are more distinct in P. occidentalis as compared
to P. modesta.
There may be naturally occuring hybrids in Laramie.
The grey-blue eyespot of the hindwing gives this species its name.
Larvae feed on birches, willows, cherries and oaks.
The outer edge of the forewings is quite scalloped.
This small species is widespread and common and is likely present. This species ranges across North America.
The hindwings have a small blue eyespot ringed with black on a yellow background.
If you have willows and poplars nearby, you've probably got populations of
the Cerisyi's Sphinx.
The hindwings are quite striking.
Snowberry Clearwing or Bumblebee Moth
This moth is widespread and is present at least in the northeastern
part of Wyoming. It may fly throughout the state.
WO, the Hummingbird Clearwing
It is not difficult to see why many gardeners would mistake an Hemaris thysbe moth for a small hummingbird as it hovers,
sipping nectar from flowers through a long feeding tube.

The outer margin is grey. There is a bright pink band on the hindwing.

This species is very widespread. It can be seen flying during the day,
into the evening and also at night.
The highly variable larvae are often found in people's gardens.
The upperside of the forewing is pale gray-green with a deep
green-brown median area and a white dash at the wing tip.
