Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Fall armyworm (Spodoptera frugiperda) is one of the most damaging invasive pests of maize, and its larvae carry a very specific identifying mark: four raised black spots arranged in a square on the dorsal surface of the second-to-last abdominal segment.
Along with an inverted "Y"-shaped marking on the head, this square-spot pattern is exactly how entomologists tell it apart from similar-looking caterpillars such as cutworms, stem borers and ordinary armyworms.
Since the question describes precisely this square arrangement of spots, Fall armyworm is the pest being described.
