Green Caterpillar with Parasite?

Asked October 13, 2020, 11:53 PM EDT

I found this caterpillar in Lake County near Baldwin. It looks like it’s maybe a Sphinx Moth? And are the brown things on it a parasite or growth? Thanks! Todd

Hello,

This looks like a tomato hornworn, that as an adult is a type of hawkmoth.

The objects on its body are the pupae of parasitoid wasps.
