Appears to bore right into lily stalk, found like 3 boreholes.

I have had that exact same thing in a few lilies the last few years. I have no idea what it is. It's strange.

Here is some info ~ http://ipm.ncsu.edu/ag295/html...

I thought I had heard that they most often inhabit corn. The weeds behind my fence are the problem in my case. It makes it ridiculously difficult for me to keep up with that area near the fence.

Thanks for the info Moby.

Thanks Moby.
