June Bug Grub

Phyllophaga sp.


Adult beetles, commonly referred to as May beetles or June bugs are ½ to 5/8 inches long, and reddish brown. White grubs are "C"-shaped larvae, up to 1 inch long, with cream-colored bodies and brown head capsules. They have three pairs of legs, one on each of the first three segments behind the head.


Habitat, Food Source(s), Damage: Mouthparts are for chewing. Phyllophaga crinita is common in Texas turfgrass, particularly Bermudagrass, St. Augustine grass and tall fescue. Feeding of large numbers of grubs causes lawns to turn yellow and die. Severely damaged grass can be "rolled up" like a carpet. Grubs also feed on the roots of weeds, vegetable transplants and ornamental plants. In agriculture, they are important pests of forage, corn, sorghum and sugarcane. Most severe injury to plants is caused by large (third stage or instar) grubs feeding on roots in the fall and spring. White grubs are frequently encountered tilling garden soil or by sifting through soil underneath damaged turfgrass. Adults can be abundant around lights in the spring of the year.


I was raking my lawn and notice a fairly large area (4x4 feet) that was brown and had died. When I investigated the damaged area, I noticed this grub in the soil. I removed almost 50 of these grubs in this area alone.
