Grant County, New Mexico
Sphingidae

This page is inspired by and dedicated to David R. Furnas who sent me the image of the Pachysphinx occidentalis female, top of the page.

Thirty-four Sphingidae species are listed for New Mexico on the U.S.G.S. website. Not all of the species are reported or anticipated in Grant County.

It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you are likely to encounter.

A "USGS" indicates the moth is reported on the USGS website (not available on date I assembled this checklist) and/or in Lepidoptera of North America, #1. Distribution of Silkmoths (Saturniidae) and Hawkmoths (Sphingidae) of Eastern North America, an excellent little booklet available through Paul Opler.

I, William Oehlke (WO), have added a number of species whose presence I expect in Grant County.

Sylvie Post surprised me with an image of an Eumorpha typhon larva from Grant County. The image was taken by David Morehead.

Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an electronic image, via email to Bill Oehlke.

Sphinginae subfamily

Sphingini tribe:

Agrius cingulata WO possible stray

This species is a strong migrant and adults nectar from deep-throated flowers including moonflower (Calonyction aculeatum), morning glory (Convolvulus), honey suckle (Lonicera) and petunia (Petunia species).

Ceratomia amyntor, The Elm Sphinx or Four-horned Sphinx, WO,
The upperside of the forewing is brown with dark brown and white markings including a white costal area near the wing base, dark streaks along the veins, and a white spot in the cell.
Larvae feed on Elm (Ulmus), birch (Betula), basswood (Tilia), and cherry (Prunus).

Manduca quinquemaculata WO, the Five-spotted Hawkmoth
The moth abdomen usually has five but sometimes six pairs of yellow bands. The upperside of the forewing is blurry brown and gray. Larvae feed on tomatoes and go by the common name of "Tomato Hornworms".

Manduca rustica WO, the Rustic Sphinx

Look for three large yellow spots on each side of the abdomen. The upperside of the forewing is yellowish brown to deep chocolate brown with a dusting of white scales and zigzagged black and white lines.

Manduca sexta WO, the Carolina Sphinx
The abdomen usually has six pairs of yellow bands, broken across the back. The sixth set of markings is quite small. The upperside of the forewing has indistinct black, brown and white markings.
If you grow tomatoes, you have probably encountered it.

Sagenosoma elsa WO, the Elsa sphinx

The upperside of the forewing has a wide white band along the costa from base to apex. The remainder of the wing has black and white bands.

Sphinx asella WO, 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. Larval hosts are ash, lilac, privet, cherry, and quaking aspen.

Sphinx dollii WO, 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 from Nevada and southern California east through Utah, Arizona, Colorado, and New Mexico to Oklahoma and Texas.

Sphinx libocedrus WO, the Incense Cedar Sphinx

The upperside of the forewing is pale blue-gray to dark gray with a black dash reaching the wing tip and a white stripe along the lower outer margin.
The upperside of the hindwing is black with two diffuse white bands, the upper one being practically non-existent.

Sphinx perelegans WO, the Elegant Sphinx

Sphinx perelegans adults fly in montane woodlands and mixed chaparral-type vegetation as a single brood in the north, with adults mainly on the wing in June and July.

It flies from dusk until after midnight. Note dark thorax.

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

This moth has a large, heavy body, and females can be remarkably plump.

Larvae are fond of poplars and willows.

Pachysphinx occidentalis WO, the Big Poplar Sphinx

This one is quite similar to Pachysphinx modesta, with modesta being smaller and darker. The am and pm lines are distinct in occidentalis, diffuse in modesta.

Moths should be on the wing from June-August.

Paonias excaecata WO, the Blinded Sphinx,

The outer margin of the forewing is quite wavy. There is a dark cell spot and a dark oblique line mid wing from the costa almost to the inner margin. Basic ground colour is pinkish brown.

Flight would be June-July.

Paonias myops WO, the Small-eyed Sphinx

This small species is probably widespread and common. 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 or One-eyed Sphinx,

Larvae feed on poplars and willows.

Flight would be from late May-July as a single brood.

Smerinthus jamaicensis WO, the Twin-spotted Sphinx

Smerinthus jamaicensis closely resembles Smerinthus cerisyi, but jamaicensis is much smaller with larger blue patches on more vibrant and deeper purple in the lower wings.

Macroglossinae subfamily


Dilophonotini tribe:

Erinnyis ello, the Ello Sphinx, WO

The abdomen has very distinct gray and black bands.

Adults nectar at dusk so you may see them in the garen at that time, but only as very rare strays.

Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee Moth
The wings are basically clear, with dark brown to brownish-orange veins, bases and edges. The thorax is golden-brown to dark greenish-brown. The abdomen tends to be dark (black) with 1-2 yellow segments just before the end.

Philampelini tribe:

Eumorpha achemon WO, the Achemon Sphinx Adults nectar from flowers of Japanese honeysuckle (Lonicera japonica), petunia (Petunia hybrida), mock orange (Philadelphus coronarius), and phlox (Phlox). Larvae feed upon Grape (Vitis), Virginia Creeper (Parthenocissus quinquefolia) and other vines and ivies (Ampelopsis).

Eumorpha typhon SP, the Typhon Sphinx

The upperside of wings is deep red-brown with pale brown bands. Each hindwing has pink along the costal margin and a triangular white spot on the outer part of the inner margin.

Macroglossini tribe:

Darapsa myron WO, the Virginia Creeper Sphinx or the Grapevine Sphinx

The forewing upperside is dark brown to pale yellowish gray, with an olive tint. On the costal margin there is a dark rectangular patch, although this may be reduced or absent. The upperside of the hindwing is pale orange.

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 juanita WO, the Juanita Sphinx

The upperside of the forewing is pale gray-green with a deep green-brown median area and a white dash at the wing tip. The underside of the forewing is pale orange at the base.

Xylophanes tersa WO, the Tersa Sphinx

The upperside of the forewing is pale brown with lavender-gray at the base and has dark brown lengthwise lines throughout. The upperside of the hindwing is dark brown with a band of whitish, wedge-shaped marks.

Many of the Sphingidae larvae are highly variable within the species. Most darken considerably just before pupation, especially before the onset of cooler weather.
