Spodoptera ornithogalli (yellowstriped armyworm) is the evil spawn of Satan!!!
I had 4 2-gal containers all with about 1/2-3/4-inch sprouts of kale. The yellowstriped armyworm caterpillars ate every bit of them within about 2 days
They also got all of my new cherry tomato sprouts and I found one hammering a pepper plant today.
ARRGGHHHHHH!!!!
