DISTRIBUTION:

The Banded Sphinx Moth, (Eumorpha fasciatus fasciatus), wingspan 3 7/16 - 3 13/16 inches (8.7 - 9.6 cm), flies in
northern Argentina: Buenos Aires, Corrientes, Chaco, Formosa, Misiones, Santa Fe (VLG image), Entre Rios (LA);
Bolivia: Beni, La Paz, Santa Cruz;
Paraguay: Asuncion, Concepcion, Boqueron, Presidente Hayes, San Pedro, Canindeyu, Central, Cordillera, Caaguazu, Alto Parana, Paraguari (possibly Misiones and Itapua (WO??));
north through Central America:
Mexico;
Belize: Corozol, Orange Walk, Cayo;
Guatemala;
Honduras;
Nicaragua: Carazo, Rio San Juan, probably Rivas and elsewhere;
Costa Rica: Guanacaste, Puntarenas, Limon, Alajuela, Heredia, San Jose, Cartago;
Panama
to southern California and southern Arizona; east to Texas, Mississippi, Florida, and South Carolina. The moths strays north (migrates) to Missouri, Michigan, Indiana, Iowa (TJ), Pennsylvania, New Jersey (Monmouth County, September 5, 2010), New York, and Nova Scotia. On October 19, 2007, I received an image of a somewhat tattered live specimen from southern Minnesota, courtesy of Roxanne Goodrich.

It also has an extensive range in South America, and flies in southern Argentina;
Uruguay;
Brazil: Amapa, Ceara, R.G. Norde, Paraiba, Rio de Janeiro, Parana;

Colombia;
Ecuador;
Peru.

With very strong migrating tendencies this moth can probably be found wherever there is sufficient moisture for its larval hosts.

It should also be throughout the Carribean:
Dominican Republic;
Puerto Rico;
Virgin Islands;
St. Kitts;
Montserat;
Guadelupe;
Dominica;
Martinique;
St. Lucia: Dennery;
Bonaire;
and other islands.

I have never seen them on Prince Edward Island, Canada.

The upperside of the moth is dark pinkish brown. Each forewing has a lighter brown band along the costa, and sharp pinkish white bands and streaks. The hindwing has a pink patch on the inner margin and pink along the outer margin, distinguishing it from vitis.

The genus name "Eumorpha" means well-formed.

"Fasciata" means bound together and possibly refers to the network of lines on the forewing, especially the thinner lines "atop" the wider ones.

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion. It is based on commonly accepted English pronunciation of Greek names and/or some fairly well accepted "rules" for latinized scientific names.

The suggested pronunciations, on this page and on other pages, are primarily put forward to assist those who hear with internal ears as they read.

There are many collectors from different countries whose intonations and accents would be different.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Eumorpha fasciatus fasciatus broods continuously in tropical regions, but in the northern extent of its range is single brooded with adults on from August til November. Veronica L. Gaitan confirms a March 5, 2011, flight in Santa Fe City, Santa Fe, Argentina, with an image, but she indicates the moth emerged in a greenhouse. Possibly the pupae came in soil of potted plant from further north.

Leonardo Aguado confirms a presence in Entre Rios, Argentina, with moths on the wing in February.

Sergio Rios Diaz confirms January-February and May flights in Paraguay.

Adults nectar at various flowers in the dark. Eumorpha fasciatus fasciatus larvae feed upon primrose-willow, Ludwigia (water primrose) and other plants in the evening primrose family (Onagraceae). Grapes also serve as larval hosts.

ECLOSION, SCENTING AND MATING:

Pupae wiggle to surface just prior to eclosion. Females call at night, and males (below) fly into the wind to pick up and track the pheromone plume.

To the right a moth sits in the typical resting pose.

EGGS, LARVAE AND PUPAE:

Larvae are quite striking and pupate in subterranean burrows. The larvae are also highly variable in patterning and depth of color. Many have considerably more green than the one depicted to the right.

Mature larvae descend from the host to pupate in subterranean burrows. Terre Haute, Indiana, image (below), courtesy of Scott Reely.

Michael van Buskirk writes (September 2, 2007), "Was out doing a some nature walking this afternoon, about 20 miles north of me, which is actually in the next county. We have been extremely wet, and our vacant lots are getting jungle-like. Bright yellow flowers in the ditch caught my attention, since I was certain they were in the Evening Primrose family. Upon inspection, turned out they were Ludwigia. My hunch was that Eumorpha fasciatus might use this as a host, but I have never taken any at light in TX, and only have seen a few in collections from the area.

"After some searching found (19) ova and (4) ~3rd instar larvae on the plants. Only Lugwigia listed in my most reliable local plant guide Enquist (Wildflowers of the Texas Hill Country) is L. octovalis. Plants were in the ditch and many in standing water. While I do suspect this is Eumorpha fasciatus, have no reference for the earlier instar larvae. Found the ova first, and wondered if they might be H. lineata--some may turn out to be that species as well.

"Know that E. fasciatus is highly variable as a larva. I will take some better pics of the ova and earlier instars if you want for your website. Seems like you have enough 5th instar larvae, unless mine turn out to be something unusual....

"Nothing extraordinary, but was nice to find them on a Sunday walk."

Subsequently (September 9, 2007) Michael writes, "Larvae I found last Sunday are definitely E. fasciatus, since two have molted into 5th instar today. That is very fast development. Believe the Water Willow hostplant (Ludwigia octovalis) needs a lot of water, and so the species takes advantage of wet spells, like we have been having here in South Texas recently, and develop quickly. The ova I found have hatched as well, and are all in 2nd instar already as of this morning.

"Not sure if these are useful for your website, but noted you did not have earlier instar pics. Have included the three 4th instar color forms here: pink, yellow-pink, and green (109,110, 113), two just molted 5ths (105 & 106). Use what you can, or just delete. My goal is to rear all the Sphingidae of Texas, and will keep sending you images, for you to pick and choose as you like."

I very much appreciate Michael's efforts. Often the early stages are only identified/confirmed by rearing to fifth instar or even to adult moth stage. It is great to have these earlier instar images as well as the variations. Bill Oehlke

Jim Tuttle, August 24, 2005 writes, "In my experience the caterpillars of this species are the most variable of all of the sphingids. The hostplant (below) is definitely one of the Ludwigia species (primrose willows).
