Butterfly Identification for Beginners

Instead of our usual Bug of the Week, today let’s learn a bit about how to identify butterflies.

western-pygmy-blue-butterfly

Quick, do you know what kind of butterfly this is? Does it really matter?

If you want to have an active and successful butterfly garden, then it pays to know your local butterflies. That way you can tailor the plants in your garden to their particular needs.

Butterfly identification may seem intimidating, but there are some tricks to make it manageable. First, arm all your family members with cameras. A photograph can be very handy to help you study the identification details at your leisure. Second, learn the characteristics of the groups of butterflies called families. Once you have mastered those, a trip to the identification guide or website is much more successful. By the way, that butterfly in the photograph is a western pygmy blue, a member of the blue family.

Before we get started, if you are not familiar with what insect parts are called, check out our post with information about caterpillar and butterfly anatomy.

Next, if you are not sure the insect you have is a butterfly or moth, brush up on the differences between butterflies and moths at our website.

Butterfly Identification – Butterfly Families

Entomologists group butterflies with similar characteristics into families. You don’t need to memorize the scientific names (unless you want to do so). I added them so you can add them to your search terms when looking for species.

1. Family Hesperiidae – commonly called skippers

Characteristics:  Skippers are butterflies that most resemble moths. Two differences are that they tend to hold their wings at a 45° angle (rather that flat out or folded back) and their slender antennae often end in a hook.

skipper-on-lantanaYou can see the angled wings very well in this photograph.

 2. Family Papilionidae – commonly called swallowtails

Characteristics:  Swallowtails are known for their bold, contrasting color patterns and the presence of extensions or “tails” on their hind wings.

giant-swallowtailThe giant swallowtail has the characteristic look of the family Papilionidae.

3. Family Pieridae – called whites, sulphurs, and orange-tips

Characteristics:  Most are white, light yellow, or orange, and have simple, rounded wings. They are medium-sized and have normal front legs.

sulphur-butterflyA sulphur butterfly’s wings are simply elegant.

4. Family Lycaenidae – Coppers, blues and hairstreaks

Characteristics:  The members of this family are delicate, very small butterflies. The blues often have blue upper wings, whereas the coppers are brown. Hairstreaks have tiny tails on their hind wings.

hairstreak-on-dogwoodCan you see the tiny tails on the hind wings?

hairstreak-butterfly257How about on this one?

Some people think the tails resemble antennae, thus confusing predators about which end is the head.

5. Family Libytheidae- snout butterflies

Characteristics:  Snout butterflies are named for their long, hairy mouthparts that project forward from their head like a snout.

snout-butterflySee how the mouthparts extend way out past the eyes in this snout butterfly? Compare to where the eyes are in the other butterflies in this post.

6. Family Heliconiidae – called the heliconians

Characteristics:  Often brightly colored, with wings that are longer than they are wide.

zebra-butterlyThe wings of this zebra butterfly show the distinctive shape characteristic of the family.

7. Family Nymphalidae- the brush-footed butterflies

Characteristics:  This family is large and its members vary a lot in color, size and shape. The brush-footed butterflies have reduced (short) forelegs, but it isn’t an easy trait to see.

buckeye-butterfly-sunningThe buckeye butterfly in the Butterfly Gardening Week button is a brush-footed butterfly.

 8. Family Danaidae – milkweed butterflies

Characteristics:  These large brown or orange butterflies are sometimes grouped with the brush-footed butterflies. Their larvae feed on milkweeds.

2. Butterfly Nature Journals and Art Projects

As I’ve mentioned previously, keeping a nature journal or photographic record of your findings is a great idea. Tied with that, drawing or coloring butterfly illustrations helps with recognition and observation skills. Look for free, printable butterfly pages that show realistic butterflies and make some creative art projects. Be sure to take note of the important features of each kind of butterfly.

Butterfly World has downloadable (.pdf or Word) coloring books that feature the exotic butterflies found in their exhibit.

Dover Publishers has a good selection of nature-related coloring books, as well. For example:  Butterflies Coloring Book (Dover Nature Coloring Book) by Jan Sovak

On Tap This Week: Butterfly Gardening With Children

Butterfly gardening has become an incredibly popular activity. It is so easy, because all it requires is a little space and a few carefully chosen plants. It can be an extremely rewarding activity to carry out with children, who can experience hands-on science at its best while learning about topics like pollination, insect life cycles, and weather. We are so excited about it that we are going to devote a week of blog posts to butterfly gardening with children.

Zinnias: Flower Cycles and Parts

If you have been following Growing With Science, you know that we have been closely observing the insects on a small planting of zinnias for the last few weeks (posts about zinnia insects 1, 2, and 3).

mix-of-zinnias-87

The variety of zinnias we have been observing are Profusion® Fire, which are hybrids between regular zinnias (Zinnia elegans), and the Mexican or narrowleaf zinnias (Zinnia angustifolia).

While initially observing the insects on the plants, we also noticed something about the plants themselves, specifically the flowers. Do you notice anything about the flowers in the photograph above?

As it turns out, the flowers change as they become older.

tightly-closed-zinnia-bud-63The zinnia flower head starts out as a tightly closed bud.

young-red-zinnia-flower-19

When the flower head first opens, it is deep, bright orange, almost scarlet.

medium-orange-zinnia-22

As the flower head matures, it becomes a medium orange. Do you see any other changes?

old-yellowed-zinnia-11

The oldest flower heads have faded to almost yellow. They look a bit worse for wear.

There have been some changes to the flowers within the flower head as well, but we need to learn some vocabulary before we can investigate it.

Flower Parts

You may have seen a diagram like this one describing the various parts of a hypothetical flower. Basically, the ovary, style and stigma form the female part of the flower that receives the pollen. The stamens, made up of filaments and anthers, are the male parts of the flower that produce pollen.

Very few flowers actually conform to this simple diagram, and the zinnias are certainly much more complex. Rather than a single flower, what we see is actually a cluster of minute flowers called disk and ray florets.

 

young-floret-parts

You may have to scroll back up to the bigger photographs above to see the parts clearly, but in the young flower head the ray florets around the outside are flowering, which is evident by the yellow stigmas. Only a few disk florets in the center have begun to open.

 

medium-floret-parts

In the middle-aged flower head, most of the ray florets have finished flowering and many of the disk florets around the outside have begun to flower.

older-floret-parts

In the older flower heads, the outer florets have finished flowering and are developing the all-important seeds. Only the disk florets at the very center are still flowering.

Flower Part Dissection Activity for Children

Note: check whether the children have severe pollen allergies before starting this activity.

Gather:

  • Living flowers of different types (see flower notes)
  • Safety scissors and other dissecting equipment (age appropriate)
  • Diagrams/illustrations of flower part with labels
  • Dissecting microscope (optional)
  • Paper (optional)
  • Pens or markers (optional)
  • Tape (optional)

Flower notes:  Tiger lilies or other lilies are excellent examples of simple flowers as seen in the diagram. Daisies and sunflowers are good examples of the complex flowers. Working with a large group? You might want to ask your local grocery store or florist if they would be willing to donate flowers that have passed their freshness date. Keep the flowers alive in a vase of water.

Have the children observe the different types of flowers closely. Provide diagrams or illustrations naming the flower parts. Once everyone has had a chance to observe the flowers, allow the children to dissect the flowers to examine the parts more fully. Very young children can simply pull them apart. Older children might use safety scissors. Still older children can use dissecting pins and a dissecting microscope, if available.

Remove the petals or pull off the ray florets. Can you find the stigma? What about the stamens? Is the stamen releasing pollen? What color is the pollen? What is inside a disk floret?

Older children might want to spread the parts onto a piece of paper or card stock and tape them down. Label the parts.

Extension:  If the flower parts aren’t damaged too badly, allow the children resemble the parts to make their own mix of “Franken-flowers.”

The Clover & the Bee; A Book of Pollination by Anne Ophelia Dowden

This image does not do this beautiful book justice. It includes many highly-detailed, scientifically-accurate diagrams of different types of flowers with their parts labelled. It also discusses pollinators and how they use differently-shaped flowers in different ways. Super scientific reference for educators and older children.
