Not sure what's eating my Sunflower leaves. I believe it may be some kind of caterpillar. The only reason I say that is because it leaves like a dry slime behind or maybe that's something else if anybody has suggestions because it looks so similar to all those other three bugs showed to me. So I'm not really sure what it may be or how I can stop it from happening anymore I've lost a lot of plans because of it! They also go after my Morning Glory plants too...

Leaves look eaten with a dry slime left behind. Starts at bottom and works it's way up.
