A nighttime beetle whose grub-like larvae chew on plant roots, sometimes killing shrubs like azaleas and yews.

You'll rarely see the adult weevil itself since it only comes out at night and hides in mulch during the day. The giveaway sign is leaf edges with small crescent or half-moon shaped notches chewed out. Underground, look for C-shaped white larvae feeding on roots and the base of the stem.
