What is this insect? Is it a pest?

Is it a pest?



Answer: This is a seed bug in the Lygaeoid group, probably Nysius species or the false chinch bug. They tend to aggregate and feed on plant leaves and seeds using piercing sucking mouthparts. Heavily infested leaves may turn yellow. In most situations, Nysius bugs are generally not economic insect pests, but they are considered an occasional insect pest of wheat and vegetables. I had reports of these Nysius bugs feeding on potato, canola and soybean this past week in North Dakota and Montana.
