And Hayfields Green June beetles are most likely to cause damage in fields where broiler litter or other organic matter has been applied. Green June beetles cause a general loss of productivity and allow less desirable grasses such as crabgrass and common bermudagrass to invade. In heavy infestations, a pasture can be completely destroyed. Good weed control can lessen the impact of this pest. Green June beetles tend to congregate on broad-leaved weeds such as spiny amaranth and jimson weed.
Females look for open patches of ground where they can burrow into the soil and lay eggs.
Usually, there is a small patch of open ground at the base stems of broad-leaved weeds. Bare patches from previous green June beetle feeding also make it easier for green June beetle females to get into the soil to lay eggs. In a heavy infestation, the entire pasture may be damaged. More frequently, the grub infestations are patchy. Edges of terraces, sunny slopes, slopes down from barns, and cattle feeding sites are all likely to be infested.
