I didn’t think it was a June Bug grub looking from above. They have the brown head and are black/ dark blue on the rear side under the translucent white. It is impossible for me to identify from above. A side view would be more helpful.
Looking at the picture again, I think I was looking at it as if its head was on the top of the picture. Looks kind of like a June Bug grub if the head is pointed down.
Its been a while since I have seen one, but those black dots near the head look familiar for a June Bug.
They also make great panfish or any other fish bait. I caught my PB from Moore Lake bullhead with one when I was a kid.
Did you dig them up? I’ve never seen a grub above ground, I’ve always dug them up.
