What is an example of an insect that feeds on the surface of grass?

The chinch bug is an example of an insect that feeds on the surface of grass. This insect is known for its feeding behavior, which involves piercing the grass blades and extracting sap, leading to a characteristic yellowing and wilting of the turf. Chinch bugs are more often found in the sunny, stressed areas of lawns, making their activity particularly visible in these regions. Their presence can significantly damage cool-season grasses, especially during dry periods, as their feeding leads to a decline in the overall vigor of the turf.

In contrast, the white grub primarily feeds on the roots of grass plants, leading to different symptoms such as poor root health and overall plant decline, which can also be damaging but in a different manner. Billbug larvae also feed on the plant tissues, but they target the stems and crowns, causing distinct damage. Root weevils, similarly, are known for feeding on the root systems, impacting the grass at a deeper level. While all these insects can be detrimental to grass health, it is the chinch bug that specifically feeds on the surface, making it the correct example in this case.
