Sphingidae

Sphinginae subfamily

Sphingini tribe: Ceratomia amyntor WO, the Elm Sphinx or Four-horned Sphinx 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). Ceratomia undulosa WO, 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. It is named for the wavy lines on the forewings. Manduca quinquemaculatus 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. I suspect if you grow tomatoes, you are likely to encounter it. 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 drupiferarum WO, the Wild Cherry Sphinx Forewings, long and slender, are held close to the body when the moth is at rest. 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: Amorpha juglandis WO, the Walnut Sphinx The adults are also highly variable; sometimes wings of an individual may be all one color or may have several colors, ranging from pale to dark brown, and may have a white or pink tinge. Patterns range from faint to pronounced. See the file for the female; she is different. Pachysphinx modesta WO, the Modest Sphinx or Poplar Sphinx It is fond of poplars and willows. This moth has a large, heavy body, and females can be remarkably plump. 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. Paonias myops WO, the Small-eyed Sphinx Named for the small eye-spot in the hindwing, this moth has a wide distribution. Both sexes rest with wings parallel to the resting surface, with the upper lobes of the hindwings protruding above the forewings. 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: Aellopos titan WO, the Titan Sphinx. The body is dark brown with a wide white stripe across the abdomen. The wings are dark brown. It is very similar to above species, but the upperside of the hindwing has pale patches along the costa and inner margin. if present, only as a stray See Hemaris comparison to help distinguish the next two species. Hemaris thysbe 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. Hemaris diffinis WO, the Snowberry Clearwing or Bumblebee Moth Adults mimic bumblebees and are quite variable, both geographically and seasonally. The wings are basically clear, with dark brown to brownish-orange veins, bases and edges. The thorax is golden-brown to dark greenish-brown. Philampelini tribe: Eumorpha achemon MBZ, the Achemon Sphinx This moth is now officially reported for Edmunds County, but it is fairly often reported along the coast from southern New Jersey to central Maine. Note the differences between this moth and the Pandorus Sphinx. Eumorpha achemon, Bowdle, July 20, 23, 2011, MyRon B. Zimmer 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. Deidamia inscriptum WO, the Lettered Sphinx The moth's outer margin of the forewing is deeply scalloped. The upperside is light brown with dark brown markings. There is a small black and white spot near the tip Hyles euphorbiae WO, the Spurge Hawk Moth The body is light brown with various white and dark brown markings, while the wings have a conspicuous tan, brown, and pink or red color pattern. Hyles gallii WO, the Bedstraw Hawk Moth or Gallium Sphinx Larvae feed on Epilobium angustifolium and Galium. I expect flight is late May-July with a possible fall flight as well. Hyles lineata WO, the White-lined Sphinx The forewing upperside is dark olive brown with paler brown along the costa and outer margin, a narrow tan band running from the wing tip to the base, and white streaks along the veins. 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. rare if present Sphecodina abbottii WO, the Abbott's Sphinx This moth is very much under reported across the United States. It is a rapid day flier so is probably not in too many collections. Grape and Virginia Creeper are popular larval hosts. generally more easterly
