Abbott's Sphinx, Sphecodina abbottii 7870. Regardless of the subject matter I post, I always mention that we have favorites in a group. For the Sphinx Moths, this is it, maybe because it's so different. The body is not long and torpedo shaped like most. It is short and fat, with tufts of light hairs sticking out the rear. The forewings are deeply scalloped, and the pattern reminds me of finished wood grain. The bright yellow hindwings, and the noisy flight pattern make this a Bumble Bee mimic.
Of all the caterpillars I wished I had photographed, this is by far the neatest. It's brown and covered with lime green circles. Instead of a horn at the back end, it has a rather intimidating, 3D fake eyeball.
Slender Clearwing, Hemaris gracilis 7854. The Slender Clearwing is rare in Ohio, and I have no picture of one. It looks very similar to the Hummingbird Clearwing except for the cell in the wing. It's small and round, but has NO vein in the center.
Tobacco Hornworm, Manduca sexta 7775. It's also known as the Carolina Sphinx. It looks nearly identical to the next species, the Tomato Hornworm. On this species there are 6 pairs of yellow spots on the abdomen, but the last pair is small, and not always easy to see. The first pair of yellow spots is bordered by a very small white line and essentially borders a large black spot. The overall color is brown. The hindwing has one thin brown line near the base, and two thick brown lines further out.
Great Ash Sphinx, Manduca jasminearum 7783. The black U shaped marks coming down into the forewing are often absent. Same goes for the orange spot. The horizontal black lines are more reliable for identification, as are the black hindwings. Currently this is s common species in Ohio, but with the Emerald Ash Borer problem, we'll have to see what happens to the populations.
Here are a couple more species that are rare strays in Ohio. You are unlikely to come across these. I will put up photos once I have found a source.
Titan Sphinx, Aellopos titan 7849.
Fadus Sphinx, Aellopos fadus 7850.
