Dispatched 3 of these green critters from my tomato plants today. Looking on the Internet, there are images of both the tomato fruitworm and cabbage looper that look just like this.

A number of leaves have been dined on. And have found 3 baby tomatoes with holes in them in the last two days (one of which is now my avatar given that it matches my Junction name... )

Might anyone be able to positively ID the creature? Thank you!

I think you can judge this plain green critter from its choice of dinner.

Yup, common sense tips the scale. Thanks @bower .
