Green cloverworms are a pest of legumes including soybeans. They are found throughout the United States and Canada and also in Great Britain. They are susceptible to disease and parasitization which often naturally keep their numbers under control.
Green cloverworms are yellow or green in color with two white stripes running the length of their body.

Green cloverworms feed on leaves, and in sufficient number can cause defoliation.
Insecticides are available for controlling green cloverworms. However, these insects are highly susceptible to disease and parisitization and so natural control is often sufficient. Always read and follow all label instructions.
