Dead spots in an otherwise healthy lawn may be a sign of white grubs. Grub damage varies from year to year and may be severe. The annual white grub is the most common grub pest of turf- grass in Kansas. It is the larval stage of the masked chafer beetle, Cyclocephala spp., which completes its life cycle in a single year. Six masked chafer species have been recorded in Kansas, all with similar developmental cycles: Cyclocephala lurida (southern masked chafer), C. borealis (northern masked chafer), C. pasadenae(southwestern masked chafer), C. hirta (western masked chafer), and Cyclocephala longula and C. melanocephala, which do not have common names.
