Can grasshoppers eat walnut trees

Grasshoppers generally prefer grasses and herbaceous plants, but they can also feed on the leaves of various trees, including walnut trees, especially if other food sources are scarce. While they may nibble on the foliage, significant damage is less common compared to their impact on crops and garden plants. However, large populations of grasshoppers can cause stress to walnut trees by defoliating them. Overall, while they can eat walnut trees, they are not a primary threat to their health.
