Hoverflies are vital pollinators and ecological indicators, yet they receive almost no dedicated welfare or conservation attention. Understanding their biology reveals overlooked welfare concerns.
The welfare status of hoverflies is genuinely unknown - invertebrate pain research is in its earliest stages, and hoverflies have received no specific welfare investigation. However, they are complex, behaviourally flexible animals capable of learning and are certainly capable of nociception at some level. From a welfare-conscious perspective, reducing pesticide exposure and habitat destruction that causes mass mortality of hoverfly populations is a reasonable precautionary measure. The ecological argument for hoverfly conservation is also strong: as major pollinators and pest controllers, their decline represents a loss of ecosystem services that benefits all wildlife.
