Globally, bees are the most important pollinators because they visit flowers to collect pollen for their larvae, as well as feeding exclusively on the nectar of flowers as adults. The entire life cycle of bees is dependent on interactions with flowering plants. While adult hoverflies feed mainly on nectar and pollen, the larvae of many species are voracious predators of aphids and other pests. As a result, hoverflies contribute to both pollination and pest control.
However, our pollinators are in decline, mainly as a result of the loss of natural and semi-natural habitats. The problem is serious. In order to ensure the sustainability of our food production, to avoid additional economic impact on the agricultural sector, and to protect the health of the environment, it requires immediate attention.
