Cover: Insect herbivores depend directly on the density of their host plants and the nature of this relationship varies across time and space. Nerlekar (2018) examines this relationship across time using a tropical perennial herb, Jatropha nana, as a system. Seen in the photograph are the instars of the jewel bug Chrysocoris purpureus feeding on the fruits of Jatropha nana.
