Please help me identify this catepillar
I woke up this morning and went outside to check on my various plants and noticed there were 2 holes in the top of one of my green tomatoes. I also noticed there seemed to be some kind of web at the top of the tomato which is where the catepillar was hiding. I googled tomato horn worm and tomato fruit worm but this does not seem to be either.
What kind of catepillar is this and would using bt be effective?
