I was recently alerted by Curt Lehman of a sighting (September 2, 2013, with image) in Brooke County in northwestern West Virginia. This represents an eastward expansion of its known range.

I identified the moths below based primarily on the distinct pale markings of the forewing apex, but more so by the pale submarginal area with short, thin, black dashes emanating toward the body from the midpoints of the dark areas of the fringe.

I do not know if there is any correlation between the dog's illness and the moth, but larvae of Ceratomia hageni feed on foliage of Maclura pomifera (Osage Orange) and the fruit and foliage are known to contain certain toxins.
One website reports, "Contact with the sap from this tree can cause dermatitis (Schur 1932). Subsequent reports (Muenscher 1951, Gardner & Bennetts 1956, Schwartz et al. 1957) are brief and may all derive from Hurst (1942) and/or Schur (1932). It is by no means clear whether the sap is irritant or sensitising or both."
The dog's illness may not even have been directly related to the moths, but I would not be surprised if the milky sap of this plant can cause allergenic reactions in and of itself, and I also would not be surprised if it binds itself to certain toxic substances either naturally occuring in the soil or introduced through environmental spills or discharges.
Vernon A. Brou confirms there are at least four generations annually in Louisiana.
