How long do weevils live without food?

Adult weevils, especially granary and rice weevils, can survive surprisingly long periods without food, often up to a month (around 30 days), sometimes even longer, allowing them to travel to find new food sources, as they typically lay eggs inside grain kernels which become their food source. Their ability to go without food depends on the species, but they're built for endurance when their food (stored grains) isn't immediately available.
