Do weevils have a nest?

No, weevils don't build traditional nests but create protected environments for their eggs, often by boring into plant parts (like seeds or bolls) or rolling leaves, effectively making a secure "pocket" or "cradle" for their young, ensuring food and safety from predators. Some species lay eggs in clusters on the ground near host plants, while others, like grain weevils, deposit eggs directly inside kernels, sealing them shut.
