Why do lilies fall over after they bloom?

This black grasshopper looking thing, is it a locust? It began small, 1/4 inch, now it is about 1 to 1/2 inch and my beautifully healthy lily plant is eaten away. They eat and live on the leaves. There is a golfball size hole in the side of the woody stem. The plant is 5 or 6 years old. I squirt them off the plant but they are back the same or next day. I have had them as big as grasshoppers. Can you give me a natural pesticide to save my plant, if I can?
