Update to Hemaris taxonomy by Schmidt
Update to Hemaris taxonomy by Schmidt - this specimen fits Hemaris aethra according to new publication by Schmidt on Hemaris, out now - http://www.mapress.com/j/zt/article/view/zootaxa.4399.1.2
Schmidt's article abstract includes this text:
"Through integrating molecular, morphological and natural history evidence, nominal Hemaris diffinis (Boisduval) of eastern North America is shown to include a second, cryptic species, Hemaris aethra (Strecker) stat. rev. Despite highly divergent mtDNA sequences and differing larval phenotypes, genitalic morphology, habitat and larval host plants, adults of H. aethra and sympatric H. diffinis are externally so similar that H. aethra has remained unrecognized for over a century..."
The description of the larva reads:
"Larva. The larva of H. aethra is distinctive: it is the only North American Hemaris with bright red spiracles, a yellow prothoracic collar and a pink-purple caudal horn with black apex (Fig. 7). By comparison the spiracles of H. diffinis are invariably black (Fig. 8), and yellow-orange in H. thetis. The base of the caudal horn is pinkish-purple, occasionally yellow grading into pinkish edging (Fig. 7a), unlike the bright yellow base of H. diffinis (Fig. 8). Neither the brown morph (Fig. 8a) nor the bicolored green/dark-brown morph found in H. diffinis and thetis have been found in H. aethra. The apex of the horn is often curved slightly caudad, while that of H. diffinis is often curved forward (Tuttle 2007), but this was not a consistently diagnostic trait in the material reared during this study. Despite the moderate body of historical literature describing H. diffinis larvae, I could find no accounts ascribable to H. aethra larvae."
How do I get these images moved to Hemaris aethra?

Found on the ground crossing
Found on the ground crossing an access road, so there is no host plant information. There is a doppelganger for this specimen here http://bugguide.net/node/view/437425, which was found in Lake Superior Provincial Park, which is identified as Hemaris thetis by David Wagner (caterpillar guru); I am aware H. thetis is considered restricted to the west, but now that fellow's image (#437425) is not the only one that looks H. thetis-y in Ontario... I contacted entomologists at Cornell who stated the colour of the caudal horn on my specimen looks good for Hemaris gracilis, but H. gracilis should have pink in the ridge circling the head, and mine doesn't fit H. thysbe either, and is definitely not H. diffinis...
