Question about my sedum!

Question about my sedum!

Is this natural for my sedum (sedum cauticola) to go from this: sedum to this? sedum what is eating it? Here is a more pretty before picture taken last June: sedum I think something is eating it? What should I do? :( sedum Close up of the nibbled "stalks" Please pardon the weeds. I left my gardening gloves at my in-laws and haven't been out weeding in some time. I am in zones 5-6 (SE Michigan) I tagged but not sure what else to tag this post. As always, thank you so much for your help and suggestions!
