can someone help me identify this caterpillar please

Hello Everyone

I will include photos of my decimated veggies and the caterpillar. For the last 3 weeks I have been coming to find many of my carrots and kale cut at the base with the top just laying there and many just eaten. Most of the damage seemed to have been occurring at night. Today I found this caterpillar eating one of the carrot plants. What is the likelihood that this type of caterpillar has been causing most of the damage? Or I just happened to have caught this one in action, but he is one of a whole variety of bugs eating the plants? What type of caterpillar is this? And finally, what suggestions do people have that could assist me in allowing my veggies to grow to harvest time?

Thank you

Are you in the United States?  It could be the Yellowstriped Armyworm.  https://content.ces.ncsu.edu/yellowstriped-armyworm

Where I live on the high plains we sometimes get huge numbers of fall armyworms that love everyone's irrigated fescue.  They will happily eat my clover too so I know they're not picky.

EDIT: I should add that BT is organic and will take care of them if you want to go that route.  I'm sure crawling across the top of diatomaceous earth would also not be a fun experience for them.
