1. Appearance: Nymphs are typically smaller and have a more slender body compared to grasshoppers. Nymphs also have shorter wings and are usually more colorful and vibrant in appearance.
2. Development: Nymphs are the immature stages of grasshoppers, undergoing several molts before reaching adulthood. Grasshoppers, on the other hand, are fully developed adults capable of reproduction.
3. Behavior: Nymphs are more vulnerable and tend to stay closer to the ground, feeding on smaller plants and vegetation. Grasshoppers, as adults, are more mobile and capable of flying longer distances in search of food and mates.
