DISTRIBUTION:

The Pawpaw Sphinx or Blackalder Sphinx, Dolba hyloeus (Wing span: 2 - 2 11/16 inches (5 - 6.8 cm)], flies from Maine south to Florida, west to Wisconsin, eastern Oklahoma, and south to Texas. New York is the specimen type locality. The moth also flies in southern Ontario.

Mike Van Buskirk has sent an image of a larva from central Texas (Kendall County), probably the western limit of its southwestern range.

The upperside of the forewing is dark brown with a dusting of white scales. Some moths have patches of reddish or yellowish brown on the wings.

FLIGHT TIMES:

Dolba hyloeus adults fly as a single brood from June-September in northern portions of its range and as two flights from March-September in Florida and Louisiana.

ECLOSION:

Pupae probably wiggle to surface from subterranean chambers just prior to eclosion.

SCENTING AND MATING:

Females call in the males with a pheromone released from a gland at the tip of the abdomen. Adults nectar from deep-throated flowers including bouncing bet (Saponaria officinalis), Petunia, jasmine, and mimosa.

EGGS, LARVAE, PUPAE:

Larvae feed on pawpaw (Asimina triloba), littleleaf sweetfern (Myrica aspleniifolia), possum haw (Ilex decidua), and inkberry (Ilex glabra) as well as Tall Gallberry Holly (Ilex coriacea). Louis Handfield reports larvae probably feed on Ilex verticellata in Quebec.

Annie Runyon sends the image of a Dolba hyloeus caterpillar devouring the Yaupon (Ilex vomitoria) foliage in her yard in Wake County, August 17, 2012.

Annie writes, "On August 17, 2012, I photographed (not very well, sorry) this caterpillar eating yaupon leaves in my yard in Wake County, NC. (Yaupon is plant from yard on Ocracoke Island, Hyde County, NC. I am growing it here for tea.)

"Ed Corey suggests it is a Dolba hyloeus and so I ended up reading about them on your fine website. I noticed no one has reported them eating yaupon, so I thought you might be interested. Unfortunately, all that remains of the cat today is black blood on leaves below where it rested overnight. But now that I have seen one, Iíll look for more ... and in my pawpaws as well."

I reply: "Hi Annie,

"Ilex vomitoria is a close relative to many of the other Ilex species known as hosts, so it is not such a big surprise. Yes, it is Dolba hyloeus, and I would like to post an image, credited to you, to a Wake County thumbnail checklist page I will create?"
