Grasshoppers can live without food for about two weeks, depending on the conditions they are in. However, their survival without food varies based on factors like temperature, humidity, and their developmental stage.
In warm, dry conditions, grasshoppers tend to dehydrate quickly, which can shorten their lifespan without food. Conversely, in cooler, more humid environments, they might survive a bit longer without nourishment. It’s also worth noting that young grasshoppers generally have a higher survival rate without food than adults do.
