Night_Bloom, I had no idea there was such a forum here and was referring to gardening only. I guess you can't have the cake and eat it.
I happen to have an aversion to tomatoes, so I love to see sphinx moths.
I am still searching for this one. I still haven't finished looking at moth caterpillars. I found one similar one. Does it have small white dots? I can't tell from the photo. I know I have seen this caterpillar before and just can't remember its name. . Does it look kinda like this Nadata gibbosa ? http://bugguide.net/node/view/1795
