Hoverflies
Hoverflies are important naturally occurring beneficial insects in farms, nurseries, gardens and field margins.
Adult hoverflies often feed on nectar and pollen, while the larvae of many species feed on aphids and other small soft-bodied pests.
Why Hoverflies Matter
Hoverflies can contribute to natural aphid suppression, especially where flowering resources are available nearby.
They are particularly useful in diverse growing systems with:
- Flower margins
- Hedgerows
- Mixed planting
- Low insecticide pressure
- Continuous nectar and pollen sources
Life Cycle
Adult hoverflies visit flowers for nectar and pollen.
Females lay eggs near aphid colonies or suitable prey.
Larvae then feed on aphids and other small insects.
Pests Attacked
Hoverfly larvae commonly feed on:
- Aphids
- Small soft-bodied insects
- Early pest colonies
Supporting Hoverflies
Useful flowering plants include:
- Sweet alyssum
- Phacelia
- Buckwheat
- Dill
- Fennel
- Coriander
- Yarrow
- Calendula
Practical Value
Hoverflies should not be viewed as a replacement for commercial biological control programmes.
Their value is in background suppression, biodiversity support and reducing the risk of aphid population explosions.
