My mint plant mysteriously died ALL OF THE SUDDEN outside so I brought it in and it started growing new stems and leaves and is doing amazing... Last night I noticed what looked like a clump of dirt and twigs hanging from one of the stems. At first I didn't think much of it and then decided maybe it was a nicely camouflaged cocoon so I let it be. This morning it was gone completely. This evening it was at the end of another stem where a leg should be. And I thought I saw it move. So I cut the stem off, put it in a jar an put a new fresh stem with fresh leaves in the jar. 20 minutes later it had mysteriously moved from the leafless stem to the fresh stem and already had eaten halfway through a new mint leaf. It seems to have no legs and I've never seen it move more than a wiggle... But obviously it's moving at some point to have eaten the hell out of all the leaves on my indoor plant! Please help I just want to know what in the world it could be. Google has provided no help this far...
Thanks!
