White grubs are up to 1-1/4 inches in length with a creamy white body and reddish-brown legs and head. These grubs are the larvae of scarab beetles, including May beetles, Japanese beetles, masked chafers and others. Typically, they are found curled into a C-shape.
Damage is due to feeding on seedling roots, with extensive feeding causing wilting and seedling death. Severe damage may occur where soybeans follow sod, cover crops, or weeds. Damage can be more severe when emergence and growth is delayed by cool, wet soil. They are found throughout the Midwest and South. |
