Here the sphinx is illustrated in Pen and Ink (Rapidograph), with the proper wing position, on Mylar Matte-Acetate. It took about 3 days to stipple all these dots. Wrist workout!
Sphinx Moth in Pencil: I later moved the forwings down and the hindwings up a bit. But what you see is what the specimen really looks like. I found it feeding on rose-of-sharon.
Here's specimen 1: The White-Lined Sphinx Moth. I know now that the forwings are extended too far forward. But I like how they are in-line with the antennae. The color is so great. Stunning.
