Step-by-step solution
Gregarious pest: A pest is an animal that is detrimental or harmful to humans or human concerns. Locusta (locust) is a pest that is dangerous to crops. It causes heavy damage to the vegetation. As it lives in groups of the same individuals but does not help one another, hence called gregarious. Body symmetry of Echinoderms: The adult echinoderms are radially symmetrical, but their larvae are bilaterally symmetrical. The echinoderms are unique in this feature that the larvae are bilaterally symmetrical (an advanced
