Orange and Blue

Mine are the fat white worm looking grubs. I haven't seen anything that looks like those beetles...at least that I noticed.

Not sure if it's just a coincidence but the first time I ever saw those white grub worms is when I dug up my septic field to replace it I found them in the soil. Then ever since I started getting more and more dead brown circles all over the yard.
Not sure if I stirred them up?

I never did any digging to see what the grubs looked like. I was very familiar with the adults that were chewing up my linden tree.

When my buddy explained his solution, all he said was his yard had "grubs". Without doing any research, I followed his path with the milky spore treatment. This morning I searched for "japanese beetle grubs" just to see what they looked like:
