Identification:

Grubs are white and c-shaped. They have brown heads and you can often see their dark body contents through their transluscent skin. Grubs can range in size from 1-2 inches in length.

Habitat:

Grubs can be found in the top 4 inches of soil, entangled in the roots of grasses and conifers.

Overview:

Grubs are often considered pests because they chew on the roots of seedlings and plants. Lots of effort is put into eliminating them from yards and agricultural fields.

Fun Fact: 

Grubs are actually the larvae of beetles! The local grubs will mature into two species of beetles: the European chafer (Rhizotrogus majalis) and the Japanese beetle (Popillia japonica).
