Phyllophaga crinita is common in Texas turfgrass, particularly bermudagrass, St. Augustinegrass and tall fescue. Feeding of large numbers of grubs causes lawns to turn yellow and die. 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. 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.
