Tips on Butterfly Watching

Finding and Watching Butterflies

Butterfly watching is an excuse to slow down, spend time outdoors, and pay attention to the small things happening around you. You don't have to identify everything you see. Every observation is an opportunity to learn something new.

Be curious, be patient, and enjoy the search!

Resources:

  1. Butterfly Field Guide--The guide will also provide information on flight times, range, the foodplant (caterpillar food), and nectar sources (adult butterfly food).
  2. A Checklist of butterflies for your region of the state or country.
  3. Close-focusing binoculars will help you see details of pattern and color that are often necessary to identify the butterfly.

Use of these resources will make your search easier and your identification more certain.

Finding Butterflies:

  1. Seek out open areas with a variety of natural vegetation, especially flowering plants. Butterflies sometimes rest in the sun to warm their flight muscles (basking), and are most active during midday on a sunny, warm (~60 degrees F), and windless day.
  2. Walk slowly and watch carefully for flying butterflies and those perched on flower heads, blades of grass, leaves of shrubs and trees, and those resting on moist ground or along the edges of puddles. Some perched butterflies rest with wings open while others have their wings closed. They are often hard to notice unless you patiently observe your surroundings.
  3. Pick a promising area that is relatively close to home and begin exploring it at frequent intervals during the Spring/Summer season and at different times during the day from 9 am to 3 pm. Record your observations and make notes of date, species seen, weather conditions, temperature and hours spent exploring.
  4. Adult butterflies can be found taking nutrients (nectaring) on flowers, from sap on tree trunks, rotten fruit, and dung. Often, male butterflies are found on a favorite perch (perching) waiting for a passing female or are flying back and forth in a territory (patrolling) on the hunt for a mate.  Males also gather on moist ground to take mineral salts used in reproduction (puddling), or are found flying at the peak of hills (hilltopping). Caterpillars are sometimes located feeding if you find the right larval foodplant (host plant). Butterflies found feeding or mating are sometimes easier to approach for close and prolonged observation.

Identifying Butterflies:

When a butterfly is first observed in the field or garden, notice as many features as possible BEFORE turning to the field guide.

  • Relative size (large (>2-1/2”) - like swallowtails; medium (1-1/2 to 2-1/2”) - like most brushfoots; or small (<1-1/2”) - like grass skippers or blues)
  • Shape of wings (rounded, pointed, or with forewings truncated)
  • Posture (open or closed wings) when perched
  • Color and pattern on the wings
  • Flight pattern (close to ground or higher) and flight behavior (wings flat or at an angle)
  • Behavior (basking, nectaring, perching/patrolling, puddling, hilltopping, courtship/mating, ovipositing (laying eggs))

All of these observations will provide helpful clues. Your observation and identification skills will improve with continued practice and time spent in the field.

  1. Try to place the butterfly in the right family.
  2. Butterflies are seasonal, and each species flies at certain times during the year (flight) and only in certain parts of the country (range) and in certain types of plant associations (habitat). A good field guide will help greatly with these aspects of butterfly watching.
  3. Explore areas like fields of wildflowers, hilltops, canyons, stream sides, marshes, trails and roadsides in open space areas. All of these areas provide different habitats and should yield a variety of butterflies.
  4. Don't worry if you can't identify every butterfly right away. Learning to recognize butterflies takes time and practice.

Keep Exploring

One of the best ways to learn butterflies is to visit the same places repeatedly throughout spring and summer. The species you see will change as the seasons progress.

Consider keeping a simple record of your observations. You might note:

    • Date
    • Location
    • Butterfly species
    • Weather
    • Temperature
    • Plants the butterfly was visiting
    • Interesting behavior
    • A photograph, if possible

Over time, your notes will begin to tell the story of the butterflies in your area.

Most of all, enjoy the experience!
