What is that?!

This bug was in my husband's garden today.

It was on a bell pepper plant. He is convinced that it is what has been eating his pepper plants. I've never seen anything like it before. I wish I could have gotten a better picture of it. He was just not very photogenic. He had little hooks for feet. His rear-end was sort of flat and would turn up. He was mostly gray. The strangest feature was the tube or tongue or something coming from his mouth. I spent most of the morning trying to identify him by researching online and it got my nowhere. We eventually took him out to the country and let him go in a corn field. Yes, that's right, we set free a bug. Hey, he is one of God's creatures too.
