Sphingidae family; Hawk Moths, or Hummingbird Moths – another 'last one'

Diurnal clearwing: a smaller sphinx moth
AKA Hummingbird moth

 Here is another critter that will soon disappear. The Hawk Moths, or Hummingbird Moths are fascinating.

Here are some of my giant moth photos. Most are nocturnal, I'd guess to avoid birds! Hubby was reading in the backyard the other day and a dragonfly landed on his book, carrying a spider larger than the dragonfly's head, and promptly began to eat it!

I do depend on the volunteer experts at BAMONA to help me ID them. You'll notice that the Butterfly and Moth books feature very few caterpillars. Thing is, we see them flit about the garden as moths, but it is so much easier to photograph them as caterpillars, and then they cocoon and fly away for the rest of the seasons (Fall, winter, spring.) It is most discouraging that they are hard to differentiate at the caterpillar stage.

Hubby helped with photos!

You can see the size of them!

Of course, once I get into my files, I find more of the lovely moths that I shall miss, once winter sets in.

Io moth;  Saturniidae; Automeris io

We're not sure which one my 8cm caterpillar might be, but since I've had quite a few Hyles lineata; White-lined Sphinx. They adore my phlox plants and I've battled mosquitoes in the night to get photos. Here are a few shots of the nocturnal beauties.

The Sphingidae belong to the Superfamily Sphingoidea.
Members of this family are commonly called "hummingbird," "sphinx," or "hawk" moths, and some can be mistaken for hummingbirds. Most are medium to large moths, with heavy bodies; wingspread reaches 5 inches or more in some species. The Sphingidae are strong and fast fliers, with a rapid wingbeat.
I'm thinking that this caterpillar might be the

Tersa Sphinx; Xylophanes tersa. Family: Sphingidae Subfamily: Macroglossinae

They have a fairly unmarked body.

Here is my large caterpillar buddy, found in my Wild Oregano patch. I was tempted to keep it in my aquarium, and let it morph there, but I didn't want to risk it. I found it the next day, in the same patch (such little feet) , took a few more photos and set it back down in the oregano.

Sphinx moths, Aren't they huge?

I have had expert confirmation:
