Also Known As

Syrphidae, hoverfly, flower fly

Intro

Overview

Flower flies (also called hoverflies) are a diverse family of flies that frequently visit blooms and can be important pollinators in gardens, parks, and natural areas. Many are easy to overlook because they’re small, fast, and often mistaken for bees or wasps. This page helps you recognize hoverflies, understand what they need through the seasons, and take practical steps to support them.

At a glance

Quick Facts

Food

Nectar and pollen from many small, open flowers (spring shrubs, summer herbs, fall asters)

Habitat

Larval habitat varies: aphid-rich plants, damp leaf litter, decaying wood, wet edges

Seasonality

Warm, bright parts of the day, peak activity often follows local bloom peaks

Where to look

Flower beds, meadows, hedgerows, vegetable gardens, woodland edges

Key takeaways

If you remember only three things

A quick summary you can scan in under 10 seconds.

What they do

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

What they need

A steady sequence of flowers plus larval habitat (often tied to healthy, pesticide-free plant communities).

One best action

Plant a mix of native, bloom-rich flowers from early season through late season.

Why it matters

Why they matter

Hoverflies are a “quiet workforce” in many landscapes: they show up wherever flowers and suitable larval habitat exist, including small urban gardens. Because different species use different habitats as larvae, supporting hoverflies often improves overall biodiversity.

Key Impacts

What this pollinator supports

  • They contribute to pollination while feeding on nectar and pollen, especially on open, easy-to-access flowers.
  • They can support many plant types, including native wildflowers, shrubs, and flowering trees, as well as food crops in gardens.
  • Many species visit clusters of small flowers, helping plants that bloom in umbels, sprays, or composite heads.
  • Some hoverfly larvae are predators of soft-bodied pests like aphids, which can reduce the need for sprays in gardens.
  • Others develop in damp organic matter, decaying wood, or wet edges—linking healthy soils and water-friendly habitats to pollinator support.

Identification

Identification guide

Hoverflies can look “bee-like,” but they’re flies—so a few simple features can help you separate them from bees and wasps. Watching how they fly and where they land is often as useful as color patterns.
1

Look for one pair of wings (flies have one pair; bees/wasps have two pairs).

2

Large, prominent eyes are common, sometimes taking up much of the head.

3

Many have yellow-and-black banding, but the body often looks smoother and less hairy than a bee.

4

They may hover almost motionless near flowers, then zip to another bloom.

Range and habitat

Where they live

Hoverflies occur across many regions of the world, including a wide range of climates and landscapes. Because the family is so diverse, the best habitats are those that combine flowers for adults with the right microhabitats for larvae.
Even small gardens and schoolyards can help by providing continuous blooms and pesticide-free habitat.

Common Habitats

  • Meadows and wildflower-rich fields
  • Gardens, schoolyards, and community plantings
  • Parks, ravines, and green corridors
  • Woodland edges and sunny clearings
  • Hedgerows and shrub borders

Life cycle

Life cycle and seasonality

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.

Spring / Early Season

Adults begin visiting early blooms; eggs may be laid near larval food sources (often on vegetation).

Summer / Mid-Season

Many species are most noticeable on abundant flowers; larvae develop and pupate in sheltered spots.

Late Season

Adults may focus on late-blooming flowers; some species complete final generations as temperatures cool.

Winter / Dry Season

Many persist in protected life stages (often as pupae or adults in sheltered places), depending on species and local conditions.

Late-season flowers and “messier” shelter (leaf litter, stems, natural edges) can be the difference between hoverflies finishing their life cycle or not.

Gardening guide

How to support in your garden

Provide the right food and habitat to help this pollinator thrive.

Plant these flowers

Nectar is a sugary liquid that fuels flight and daily activity, and pollen is a protein-rich food that supports reproduction for many flower-visiting insects. Hoverflies often prefer accessible blooms where nectar and pollen are easy to reach.

Mid-season

  • Native umbel-shaped flower clusters (carrot-family type blooms)
  • Herbs allowed to flower (e.g., dill/fennel-type herbs)
  • Clover and other low flowering groundcovers
  • Summer meadow wildflowers (general)

Late season

  • Asters
  • Goldenrods
  • Late-blooming native meadow flowers (general)
  • Flowering native shrubs that bloom into fall (general)
Best plant choices depend on your region; native plants are usually the best starting point.

Shelter and nesting

Hoverflies don’t build nests like bees; instead, they need the right “life-stage shelter” for eggs, larvae, and pupae. Because larval needs vary widely across the family, the most reliable approach is to create diverse, pesticide-free habitat with a mix of plants and natural materials.

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.

Threats to avoid

Hoverflies do best in landscapes with continuous flowers, varied microhabitats, and low chemical exposure. Many common “tidy yard” practices remove the very resources their larvae and pupae rely on.

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

How to help

Supporting hoverflies is very doable because they use common garden flowers and benefit from simple habitat choices. The goal is to provide a long flowering season and protect the hidden life stages in and around plants.

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.

Definitions

Glossary

Nectar

A sugary liquid produced by flowers that fuels many adult pollinators and flower visitors.

Pollen

Powdery grains produced by flowers; a key protein source for many insects and the material plants need transferred for seed production.

Habitat

The natural “home” of a species, including food, shelter, and the conditions it needs to survive.

Native

A plant or animal that occurs naturally in a region without being introduced by people.

Invasive

A non-native species that spreads aggressively and can harm local ecosystems.

Systemic pesticide

A pesticide that gets inside the plant, so insects can be exposed through nectar, pollen, or plant tissues.

Larva

An immature life stage that looks very different from the adult in insects with complete metamorphosis.

Metamorphosis

A life cycle with distinct stages (egg, larva, pupa, adult).

Bloom gap

A period when few or no flowers are blooming, reducing available food for flower visitors.
