How does the function of the stiff leathery fore wings differ from that of the more delicate hind wings?

The stiff leathery forewings, known as elytra, serve primarily as protective covers for the more delicate hind wings and the body of the insect, shielding them from damage and desiccation. In contrast, the hind wings are typically membranous and are primarily used for flight, allowing for greater maneuverability and lift. Together, these wing types enable the insect to navigate its environment effectively while ensuring its safety.
