What they do
Adult hoverflies visit flowers for nectar and pollen and can move pollen between blooms.

Family Syrphidae
Adults visit flowers for nectar and pollen, and many species’ larvae help keep plant-eating pests in check.

Key takeaways
A quick summary you can scan in under 10 seconds.
Adult hoverflies visit flowers for nectar and pollen and can move pollen between blooms.
A steady sequence of flowers plus larval habitat (often tied to healthy, pesticide-free plant communities).
Plant a mix of native, bloom-rich flowers from early season through late season.
Why it matters
Key Impacts
Identification
Look for one pair of wings (flies have one pair; bees/wasps have two pairs).
Large, prominent eyes are common, sometimes taking up much of the head.
Many have yellow-and-black banding, but the body often looks smoother and less hairy than a bee.
They may hover almost motionless near flowers, then zip to another bloom.


Range and habitat
Life cycle
Hoverflies go through complete metamorphosis: egg, larva, pupa, adult. Adults are the flower visitors you notice most, while larvae often live in very different places—on plants with aphids, in damp organic matter, or in other sheltered microhabitats depending on the species.
Adults begin visiting early blooms; eggs may be laid near larval food sources (often on vegetation).
Many species are most noticeable on abundant flowers; larvae develop and pupate in sheltered spots.
Adults may focus on late-blooming flowers; some species complete final generations as temperatures cool.
Many persist in protected life stages (often as pupae or adults in sheltered places), depending on species and local conditions.
Gardening guide
Provide the right food and habitat to help this pollinator thrive.
Mid-season
Late season
Leave some leaf litter or a "soft edge" under shrubs for overwintering and pupation sites.
Keep a few hollow or pithy stems standing through winter; cut back in spring after temperatures warm.
Maintain plant diversity (grasses, wildflowers, shrubs) to support different larval strategies.
Avoid over-mulching every surface; some species use damp organic layers and decomposing material.
Include a small damp area (where appropriate) such as a rain garden edge or consistently moist soil zone.
Habitat loss and fragmentation that reduce flower-rich areas and natural edges
Pesticides, especially systemic pesticides (chemicals that get inside the plant), which can contaminate nectar and pollen
Broad-spectrum insect sprays that kill larvae and adults directly
Bloom gaps (for example, plenty of spring flowers but few summer/fall blooms)
Climate stress that shifts bloom timing and increases heat/drought pressure
Take action
Plant for continuous bloom: include early shrubs/trees, mid-season flowers, and late-season asters/goldenrods.
Skip pesticides and "preventative" treatments; use non-chemical options first (hand removal, water spray for aphids, pruning).
Keep some natural structure: leave a small area of leaf litter, stems, and mixed vegetation for larvae and pupae.
Grow a variety of flower shapes, especially small, open blooms in clusters that are easy for hoverflies to use.
Examples
Examples from this subgroup. Status varies by region.
Eristalis tenax
This is a widely observed hoverfly that visits many kinds of flowers and is often noticed in gardens and parks. It’s also a helpful “starter species” for learning hoverfly ID because it’s common and active around blooms.
Episyrphus balteatus
This hoverfly is a frequent flower visitor, and its larvae are often associated with aphid-rich plants. In gardens, it can be part of a natural balance that reduces pest outbreaks.
Eupeodes americanus
This is a North American hoverfly often found visiting flowers in a range of habitats. Like many hoverflies, it can contribute to pollination while its larvae may help regulate some plant pests.
