A couple of years ago I saw some tomato horn worms, (big green things) with white cocoons stuck all over it. Turns out the Braconid wasp was responsible.
The wasp injects the worm with the larvae and they feed on the worm. I actually managed to capture some pics of the wasps emerging from the worms.
Death the horn worms! Actually the worms were on a Passion flower plant, not our tomatoes.
Around here we call them tobacco worms lol
Always fun to show a young one their first one,,,they
can get pretty darn big and eat a pretty good part of
a leaf if I get late on a spraying Orthene

That sounds like a scene from “Alien”.
