Syrphus ribesii is a very common hoverfly found along hedgerows, in gardens and woods. Adults feed on the nectar of flowers, while the larvae are predators of aphids. This hoverfly has multiple broods and adults are seen throughout spring and summer, while the larvae survive the winter as pupae. It creates a hum when resting by vibrating its wings.
Syrphus ribesii larvae feed on aphid-pests and the adults are good pollinators, so they should be welcomed by the gardener. Encourage them into your garden by planting nectar-rich borders in which the adults can feed.
