My strawberry plants leaves are being devoured by a mysterious little green caterpillar. It is green with no stripes or other colors, every section has a leg. It eats all the leaves except the spines. They usually are on the underside of the leaves. I also have noticed lots of black dirt like spots on the plants that are not dirt. Is it poop? Eggs? I also have noticed lots of brown moths around my strawberry plants.  Adults maybe?  Any idea what this bug is?
