Abstract

The next generation of green cloverworms is about to begin in soybeans. Green cloverworm larvae have been feeding on soybeans in central Iowa during the last 3 weeks of July, and the adults are now making an appearance at lights at night. No significant defoliation has been reported, but fields should be closely scouted during the first 3 weeks of August. Larvae can be identified by a combination of characters. They are pale green with one or two white stripes extending down each side of the body, and three pairs of prolegs in the middle of the body. Larvae also wiggle violently when squeezed; no other caterpillar in soybeans exhibits this behavior.
