Sphingidae

Hyles lineata nectaring on dandelion

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 these species in Uinta County, but I (WO) expect they are present.

Sphinginae subfamily Sphingini Tribe: Manduca quinquemaculatus WO, the Five-spotted Hawkmoth This large bodied moth flies in tobacco fields and vegetable gardens (potatoes, tomatoes) and wherever host plants are found. Sphinx asellus USGS, the Asella sphinx The upperside of the forewing is pale silver-gray with a series of black dashes, a white patch at the tip, and a white stripe along the outer margin. The upperside of the hindwing is black with blurry white bands. Sphinx chersis WO, the Northern Ash Sphinx or Great Ash Sphinx The upperside of the forewing is soft dark gray to blue-gray with a series of black dashes, one of which reaches the wing tip. Sphinx dollii USGS, the Doll's sphinx Sphinx dollii (Wing span: 1 3/4 - 2 1/2 inches (4.5 - 6.3 cm)), flies in arid brushlands and desert foothills. Sphinx drupiferarum WO, the Wild Cherry Sphinx 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. Sphinx gordius WO, the Apple Sphinx The upperside of the forewing ranges from brown with black borders through brownish gray with paler borders to pale gray with no borders. Dashes, submarginal line, and cell spot are usually weak. Sphinx luscitiosa WO, the Canadian Sphinx or Clemen's Sphinx: 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. Sphinx vashti WO, the Snowberry Sphinx 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. Smerinthini Tribe: Pachysphinx modesta WO, 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. Pachysphinx occidentalis WO, the Big Poplar Sphinx 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. Paonias myops WO, the Small-eyed Sphinx 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. Smerinthus cerisyi WO, the Cerisyi's Sphinx If you have willows and poplars nearby, you've probably got populations of the Cerisyi's Sphinx. The hindwings are quite striking. Smerinthus opthalmica MPNw Larvae feed on poplars, aspen and willows. Note different shape of double arced forewing pm line compared to the straighter pm line of cerisyi, directly above. S. ophthalmica has smoother scalloping of the fw outer margin. Macroglossinae subfamily Dilophonotini Tribe Hemaris senta WO, the Rocky Mountain Clearwing, There is probably a single brood of this montane species from May-August. The moth is seen along streamsides and in meadows in mountainous areas. Dilophonotini Tribe Eumorpha achemon WO, the Achemon Sphinx The forewing is light grey and brown with many lines, and there are dark patches near the middle of the inner margin, near the apex and near the anal angle. The entire basal area of the hindwing is pink. Macroglossini Tribe Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx This forewing is dark brown with a slightly irregular cream-coloured transverse line. The outer margin is grey. There is a bright pink band on the hindwing. Hyles lineata WO, the White-lined Sphinx 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. Proserpinus clarkiae WO, Clark's Sphinx This day flier, April-June, prefers oak woodland and pine-oak woodland in foothills. Moths nectar at a variety of flowers in the afternoon. Proserpinus flavofasciata WO, the Yellow-banded Day Sphinx. The upperside of the forewing is medium to dark brown with a faint to distinct white median band. The upperside of the hindwing is dark brown with a wide orange median band which may not reach the inner margin. The moth mimics a bumblebee.
