A fine member of the Sphinx or Sphingid group of moths.

This one popped up in my back yard. It was sheltering under a glass-topped table, I suppose thinking it was out of sight. This is the Tersa Sphinx, Xylophanes tersa (Hodges #7890). There are fifty or sixty Sphingids in my state. This is a fairly distinctive one as far as color and markings go. Note those tremendous night-flying eyes. The Sphinxes are normally very fast fliers. You are lucky to make out anything on one in a hurry during the day. Many species nectar at flowers in the day and certainly often just at dusk. They can be drawn to lights on porches or in yards as well. These animals are worth watching and knowing.

Same moth from above. Note those lovely shades that seem to mimic some fine wood grain. Wings of the Sphinx moths are often notched or scalloped as these are.

A Nessus Sphinx, Amphion floridensis (Hodges #7873), nectaring at wood sap in shady woods. In my state this is one of the more common day-flying Sphinxes. The two electric yellow bands across the top of the abdomen are easily seen when it is flying during the day.

And the exterior of the Five-spotted Hawkmoth, Manduca quinquemaculata. This is the winged version of the Tomato Hornworm. A common dusk flying moth in much of the state. The colored spots on the dorsum of the abdomen are just visible here.

The White-lined Sphinx, Hyles lineata, (Hodges #7894), which can be extremely common in some areas. This one, as with many, was attracted to lights near a hotel. White walls with lights are excellent moth gathering spots. These wing markings are distinctive.

The Snowberry Clearwing, Hemaris diffinis, (Hodges #7855) one of the commonest day-flying moths of any kind and certainly of the Sphinx group. Often mistaken for hummingbirds by, well, anyone really. Distinctive, clear wing patches like the Hummingbird Clearwing, Hemaris thysbe, but much more common. I have never found an H. thysbe.

Until now. And the rare perched Clearwing event. This is H. thysbe and it appears a bit tattered in the tail from Ed Gordon Point Remove. This place continues to flash fine insects at me. 

And one on my property also perched in April 2011.

One of the Ceratomia Sphinx moths. Likely C. undulosa, (Hodges #7787), the Waved Sphinx. There are six Ceratomia species and they are all fairly close in appearance. Also a light lover and these are big moths. Note the greenish tones among the grays and blacks.

And the caterpillar of one of the sphinx group. This is the Pandorus Sphinx, Eumorpha pandorus, (Hodges #7859). From Norm's yard. It feeds on the very common Virginia Creeper and the grapevine. Several of the cats in this group have the side markings and varied color combinations as well as the terminal horns and extensions.

A relation of the above cat. This is the Achemon Sphinx, Eumorpha achemon. Really fine red tones on the hind wing. And I am not sure frankly that the above cat is not the Achemon. The cat is supposed to be very similar to the Pandorus cat except the spots are divided into three parts. That cat may qualify.
