I just discovered very small (3/8 ") skinny, blackish catepillars nestled in the leaves of my hollyhocks, covered with a thin veil of web-by like stuff. Who invited these guys to the party? How do I dispose of the party crashers and make sure they don’t return? Or maybe, after they have had their belly-full of tender leaves they will grow up to protect the rest of the garden?
Naturallly, I would prefer not to use anything harsh to rid the garden of these guys, any suggestions. Can anyone recommend a good source on-line to identify the "bad guys" from the "good guys"?
