Hmmm loopers on tomato plants? They must have gotten lost on their way to the cole crops. :)

I'd suggest that in fact they may be very young tomato hornworms as they look almost identical when very small and it is hornworm hatching time.

Dipel is usually sufficient and yes, assuming they are hornworms, then dusting all the plants would be a good move.

They're loopers for sure. I've watched their locomotion and they have the "inch worm" movement, which I do not believe hornworms have. Regardless, I'm going to dust all the plants. Thanks for chiming in!!!
