The Royal Horticultural Society (RHS) and The Wildlife Trusts are urging gardeners to lend a hand in saving hoverflies, vital pollinators that play a crucial role in maintaining healthy ecosystems. Hoverflies, which are second only to bees in importance as pollinators, have been shown to visit more flowers than bees in some cases.
They contribute significantly by pollinating crops, protecting plants from aphids, and supporting wildlife such as birds.
However, the hoverfly population has seen a sharp decline, with a 44% drop in distribution from 1980 to 2020. Threats like intensive agriculture, harmful pesticides, urban development, and climate change have taken a toll on these insects. Hoverflies were even added to the International Union for the Conservation of Nature’s Red List of threatened species in 2022.
Despite their vital role, hoverflies often go unnoticed. These fascinating insects, known for their impressive ability to hover, are sometimes mistaken for wasps or bees. They are easily recognized by their distinctive markings, with species earning names like “Batman,” “Footballer,” and “Marmalade.”
In gardens, hoverflies are beneficial in numerous ways. Vicki Hird, strategic agriculture lead for The Wildlife Trusts, emphasizes the importance of creating an environment where hoverflies can thrive. Simple garden additions like a variety of flowers, ponds for larvae, dead wood for egg-laying, and even aphids for food can make a big difference.
Helen Bostock, Senior Wildlife Specialist at the RHS, adds that gardeners can attract hoverflies by planting accessible flowers such as aubretia in the spring, marigolds and fennel in the summer, and asters or heather in the autumn.
By providing a habitat for hoverflies, gardeners can help these hardworking insects continue their important role in pollination and garden health.
