Beneficial insects can include predators (such as ladybugs) of pest insects, and pollinators (such as bees, which are an integral part of the growth cycle of many crops).). Increasingly certain species of insects are managed and used to intervene where natural pollination or biological control is insufficient, usually due to human disturbance of the balance of established ecosys
Social learning is a beneficial means to gather information if asocial learning is particularly costly and would increase risk of predation, parasitism, or of expending unnecessary energy. In these types of scenarios, social learners may observe the behaviors of an experienced individual.
