Those are parasites on the tomato hornworm's back. If I find a hornworm
with parasites in my garden I usually move it somewhere it won't harm my
plants and leave it alone so the parasites will increase in number.

Many years ago, I actually heard one of those chewing a tomato plant 15 feet
away. That's crazy.
