White grub larvae are white and "C"-shaped. They have a light brown head, a dark tail-end, and are at most 1.5 in (38 mm) long. The true white grub can be identified by having two, parallel rows of stiff bristles on the underside of its tail end [see photo]. Annual white grubs lack this pattern of bristles.
