The insect whose economic importance is both harmful and beneficial is the butterfly. Butterflies are known for their beauty and are often considered beneficial to the environment due to their role in pollination. However, some butterfly species can also cause harm, particularly in their larval stage, as they feed on crops and vegetation. Some butterfly species have been known to damage crops, such as the cabbage butterfly, which feeds on vegetables like broccoli and cauliflower. Despite this, butterflies are still considered ecologically important as they play a crucial role in the food chain and are important pollinators for many plant species.
