Does anyone know what this little guy is? They are familiar to me and I've seen them previous years but this year there seems to be a TON of them all over one of my gardens. Last night I saw them on the leaves of an echinacea and it looked like something was eating the leaves so I assumed them but I never knew them to be an issue before. If it is these insects eating my plants, how do I get rid of them?

Thanks.
