Somethis is eating my zinnias! HELP ME!

[MariangelM]

I just started a small balcony garden for the first time, I have some basil and zinnia planted on a rail planter and those zinnias are about to bloom! Also have a pallet planter with herbs and some peppers and mint in containers. I had an extra container and decided to plant some more zinnias from seed, everything was growing well! They were even rowing faster than the other ones but a couple days ago I discovered they are being eaten! I move the planter away from the others just in case but I don’t know what it is or how to solve it! Would appreciate your help!

Same thing is happening to my zinnia , I have seen tiny mosquito like flies on the leaves, it could be them.

Could it be rabbits?
