How can the foods eaten by Orthoptera change with the seasons?

For some leaf-eating Orthoptera, dietary preferences shift throughout the year based on the seasons. While many members of this order are primarily herbivorous, these seasonal changes in plant selection allow certain species to adapt their feeding habits as different vegetation becomes available or preferred.1

It is important to note that seasonal changes are not the only factor influencing their diet. In other groups, feeding habits are determined by the insect's life cycle stage, meaning that nymphs and adults of the same species may consume different plants. Additionally, while most orthopterans are plant feeders, some species supplement their diet by preying on aphids or other weak insects, and certain katydids act as active predators.1
