I have to (just have to, ya know!) post one more photo of this caterpillar. I'd read about a parasite that lays eggs on Tobacco Hornworms but I can't say that I've ever seen it happen in our garden. Looking at the following photo, toward the bottom I spotted one white egg!
I also happen to like this photo with the whitish haze around it. Since it was mid-day and I was battling the sunshine, I reckon the conditions caused this. I'll admit, I don't know why but I'll happily accept it. I did "burn" the haze a bit to tone it down so I hope I didn't darken the photo too much. On my screen it looks okay but I don't know how it will appear to others.
