I've been concerned about some brown dry patches of grass in my lawn. I had assumed it was just not getting enough water, but yesterday when I was pulling some weeds I found the extent of the damage.
Basically the whole area just rolls up like a mat, leaving just bare soil. I saw plenty of bugs in there (mostly ants), but I didn't see any of those white grubs. I saw some bugs that looked like worms coiled up in a circle (not a great description). Is this grub damage? Looks similar to what I've seen when Googling it. Here are some pictures of the brown patch, and how it looks when I pull the grass back.
