Hoverfly Identification and Tracking

Learn to identify hover flies by their distinctive body patterns and track their flower visitation behaviors.

Hover flies (Syrphidae) are important pollinators and predators of garden pests. Their incredible mimicry of bees and wasps, combined with beautiful patterns and colors, makes them fascinating to observe. By identifying species and recording their visitation to flowers, you'll understand pollination networks and how different insects interact with flowering plants.

How to start

  1. 1
    Visit flowering areas (gardens, meadows, wildflower patches) during warm, sunny days.
  2. 2
    Photograph hoverflies feeding at flowers; capture details of body patterns and size for identification.
  3. 3
    Use online keys or field guides to identify species based on body patterns, thorax markings, and wing venation.
  4. 4
    Record observations: which flowers are visited, how long they feed, behavior (feeding, mating, resting).
  5. 5
    Note weather conditions and temperature; track seasonal appearance of different species.
  6. 6
    Join recording schemes (e.g., iRecord) to contribute sightings to databases.

Where to learn more

Plot twists

Ways to spice this up when the basics get boring.

  • Create a network map showing which hoverfly species visit which flowers; identify specialist vs. generalist feeders.
  • Photograph the same flower patches across weeks to track which hoverfly species use them seasonally.
  • Document larval behavior: where do females lay eggs, and what do larvae prey upon (mostly aphids)?
  • Compare hoverfly diversity across different flower types to identify which flowers attract the most species.
  • Track individual hoverflies across multiple flower visits within a single observation session.
ADHD notes

Observing flowers and insects can be absorbing and meditative. Macro photography sustains attention. Documenting patterns appeals to detail-oriented minds.

Fun fact

Some hover flies mimic bees and wasps so perfectly that even entomologists are fooled—but hover flies are harmless and are important pollinators themselves.
