Protecting Hoverfly ‘Heroes’: Wildlife Trust Call For Attention

In a world increasingly aware of biodiversity loss, hoverflies are often overlooked in the favor of bees. They remain at the center of an urgent conservation campaign, where lies a sense of protecting. Led by the Royal Horticultural Society (RHS) and The Wildlife Trusts, initiatives like Wild About Gardens call out to gardeners and communities to become “hoverfly heroes”. The goal inclines with watching out for the decline of the insects. 

Why Hoverfly Matters

Hoverflies are the unsung workhorses of wildlife. As the second most significant pollinators after bees, they visit 52% of global crops, pollinating plants like blackberries, apples. They also prey on aphids, safeguarding crops naturally. Beyond agriculture, they pollinate wildflowers, decompose organic matter, and serve as food for birds and bats. This makes them necessary to both food security and biodiversity.

Yet their populations are in free fall. Between 1980 and 2020, hoverfly distribution dropped by 44%. This is driven by intensive agriculture, pesticide overuse, urban sprawl, and climate change. In 2022, the International Union for Conservation of Nature (IUCN) added hoverflies to its Red List of threatened species, making a global warning. 

Towards Protecting – Threats to Survival

Intensive agriculture and urban expansion have decreased vital habitats like meadows and hedgerows. Furthermore, the widespread pesticide use disrupts their life cycles and kills both larvae and adults. Climate change necessitates these threats, altering flowering seasons and leaving hoverflies without food during critical periods. These challenges mirror a global insect crisis, with 41% of species at risk of extinction, fueled by habitat destruction, chemical pollution, and a warming planet. Without urgent action to curb these threats, the loss of hoverflies could destroy ecosystems and food systems reliant on their pollination and pest control services and lies a need in protecting them.

Becoming a ‘Hoverfly Hero’

Transform gardens into hoverfly sanctuaries by planting open-petaled, seasonal blooms like marigolds, cow parsley, and ivy for year-round nectar. Preserve habitat diversity with log piles, damp compost heaps, and “hoverfly lagoons”—shallow water features with decaying leaves for larvae. Eliminate pesticides to allow natural aphid predators like hoverflies to thrive, and embrace organic alternatives. Even small, pesticide-free gardens can become significant, protecting fragmented habitats and encouraging populations critical for pollination and pest control.

Hoverflies may be small, but their role in sustaining ecosystems is beyond our comprehension. By transforming gardens into pesticide-free sanctuaries and advocating for policy changes, everyone can contribute to reversing their decline. As Nick Packham of Worcestershire Wildlife Trust notes, “It’s time to step up for these tiny heroes—before silence falls where there once was buzz
