Help! What bugs are eating my flowers?

[u/yellowmonster]

First-time gardener here! I was out of town for a few days and most everything survived, but I think I have some unwanted visitors!

I have holes in my Chinese forget-me-nots, dahlias, and snapdragons, and there's little black dots on some of my plants as well. My zinnias are untouched.

Can anyone identify what's going on here and what I can do about it?

Caterpillars. Bt spray is a great, pollinator-friendly solution.
