What Is This 3 Inch Long Green Bug?



I spotted this well-fed green bug Thursday morning on Concord Avenue in Cambridge, Massachusetts. It was about three inches long. What kind of worm, bug, or caterpillar is this?

Hawk moth caterpillar. You'd have to get a closer look at markings to determine exactly which one.

I'm going to go with Tobacco Hornworm (which are also attracted to tomato and other related plants). I had an infestation of them one year, and this looks just like them, including the "horn" on the rear.

I'm with Kate. Hawk moth larvae don't have the horn on the end and have more distinct markings.

I believe "Hawk Moth" adult = "Hornworm" larva = Sphinx family = Sphingidae. Most hawk moth caterpillars do indeed have that little horn projecting out of the backside. While tobacco hornworm is a likely suspect, I agree with Joanna that you need a closer look at the markings to be sure - the video is too overexposed for me to tell.
