Looks like a hawkmoth of some sort. I get tobacco hornworms occasionally on my tomatoes. They eat so much so fast, that I often only notice one is there after a whole branch has been consumed. Luckily, it seems like I have a thriving population of parasitic wasps cause for the past several years, I’ve found them covered with parasitic wasp cocoons. If you find one like that, don’t remove it from your plant. By the time there are parasitic wasp cocoons on it, it doesn’t eat any more, and you could easily have 50 wasps come from one worm.
