Learning Outdoors


For our regular STEM Friday feature we recommend two books about trees for children, just in time for Arbor Day, next Friday April 24, 2015. (Read the rest of the reviews and see a video book trailer at Wrapped in Foil blog.) Then we'll finish out Butterfly Gardening With Children Week with a discussion of trees for butterfly gardens.

The first book, Branching Out: How Trees Are Part of Our World by Joan Marie Galat and illustrated by Wendy Ding (2014), describes a particular species of tree, how it used by humans, and what animals depend on that kind of tree in a series of four-page spreads. The 11 species of trees highlighted range from red maples and downy birches to pau brasil and cork oaks.

The second book, Celebritrees: Historic and Famous Trees of the World by Margi Preus and illustrated by Rebecca Gibbon (2011), consists of a series of two-page spreads telling the stories of 14 famous, tall and exceptionally-old trees from around the world, the back matter gives more information about the trees and a number of suggestions about what the reader can do to help and encourage trees.

Appropriate for butterfly gardening week:  In the section about oak trees in the back matter of this book, we find out that a single large oak tree can support up to 34 species of butterflies!

That fact reminds us that although growing pretty flowers helps the adult butterflies, to have a truly productive butterfly garden you need to supply food for caterpillars as well.

Many beautiful species of butterflies require trees as larval hosts.


1. Hackberry trees (Celtis species) are larval food for

  • Tawny emperor butterflies
  • Hackberry emperor butterflies
  • Mourning cloak butterflies
  • Question Mark butterflies
  • Snout butterfly

2. Live oaks are larval food for California sister butterfly larvae.

Some duskywings and hairstreaks also use oaks for food.

3. Black cherry (Prunus serotina) trees are larval food for:

  • Red-spotted purple
  • Eastern tiger swallowtail
  • Coral hairstreak

4. Citrus trees (orange, lemon grapefruit) attract numerous giant swallowtails. Their larvae are called orange dog caterpillars.

In addition to larval food, trees provide shelter for butterflies (and a multitude of other animals), provide safe places for the caterpillars to pupate, and some flowering trees supply nectar for many more adult butterflies.

In his book, Bringing Nature Home, entomologist  Doug Tallamy gives a list of how many species of butterflies and moths are supported by 21 kinds of trees. The numbers are astonishing! He says oak trees (genus Quercus) provide food for some 534 different species of butterflies and moths. Given that those butterflies are important pollinators and parts of the food web, that is an enormous contribution.


If you are going to plant a tree for Arbor Day or any other event, consider choosing a local species that will host butterflies. You will get yet another benefit from a tree. Please leave a comment if you have any questions about how to choose a suitable butterfly host tree for your area.

Butterflies are colorful, interesting insects. Many children find them fascinating. In fact, butterflies have become so popular that over the last few decades, butterfly houses and pavilions have sprung up all over. Children are more likely to have experienced butterflies close up than ever before. You may wonder whether you even need to plant your own butterfly garden when a trip to see butterflies is only a car ride away.

Although butterfly exhibits are educational and fun to explore, some children will be inspired to learn more about butterflies after visiting. Here are a few good reasons to consider butterfly gardening with children:

Tips for Starting Your Own Butterfly Garden

What do butterflies need to survive? Food, water and shelter are all important. Let's find out how to provide butterflies with the necessities.

1. Adult Butterfly Nectar Plants

An easy way to get started with butterfly gardening is to provide some flowering plants to provide nectar for adult butterflies. These plants may be in your yard or even in pots on your patio.

Choosing plants can be a bit daunting at first. Try taking a walk around some local gardens and note which plants butterflies are visiting. Check with local butterfly societies and plant nurseries for suggestions, as well. Ideally you want to have a range of plants that bloom over the entire growing season.

Native versus non-native plants

When you are just starting out, you may just want to try planting some old favorites, like zinnias or cosmos. Butterfly experts recommend, however, that you also include some native or local plants. For example, given a choice between:

real-butterfly-weed-dcThe butterfly milkweed (Asclepias tuberosa) which is native to eastern North America, or...


the the exotic tropical or blood milkweed, Asclepias curassavica, the butterfly milkweed is a safer bet. If you are an experienced butterfly gardener, you might want to check this .pdf article about the recent controversy about the tropical milkweed and the monarch butterfly.

Some butterfly favorite plants are:

  • milkweeds (monarchs, queens)
  • lantana
  • butterfly bush
  • ageratum (attracts male queen butterflies)
  • dill, fennel or parsley (swallowtails)
  • hollyhocks (painted lady)
  • passion flower (fritillaries)

2. Caterpillar host plants

If you are interested in raising butterflies and seeing the life stages, then it is important to provide the plants that caterpillars use for food. Caterpillars often have specific and limited feeding preferences. Look for information about your local butterflies and their hosts at websites like Butterflies and Moths of North America (click on the "regional checklists" tab).

Dill and fennel are eaten by certain swallowtail caterpillars. Butterfly gardeners always plant some extra for the butterflies.

3. Water

Even though many butterflies drink nectar, some also drink water or obtain nutrients from wet spots in the garden. Providing a damp bare spot or patch of moist sand is likely to be enough.


4. Shelter

Butterflies need places to stow away at night, and to shelter from wind and rain during the day. Providing leafy shrubs and trees, plus not being excessively tidy are great ways to ensure butterflies have safe places to hide.

This video from University of Nebraska Cooperative Extension has some good ideas.

Other suggestions:

No two butterfly gardens will be alike. They will vary according to region, size and the individual taste of the gardeners. Make butterfly gardening a family project and don't be afraid to let your creativity run wild.

Consider recording your observations via a nature journal, photographs and sound recordings. You might even want to keep a blog or share on Instagram or Flickr to inspire other butterfly gardeners. The possibilities are endless!

Do you have a butterfly garden? Have you gardened with children? What tips would you share? Have you encountered any problems? What suggestions do you have to avoid them?

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.


Our schedule:

Monday: The basics of butterfly gardening with children.

Tuesday: Figure out the five Mystery Seeds that will become great butterfly garden plants.

Edit:  The answers are now posted. See five great nectar plants for butterfly gardens.

Wednesday:  Identifying Butterflies for Beginners (with activity suggestions)

Thursday:  Pollination and butterflies (with activity suggestions)

Friday:  Adding trees to your butterfly garden.

We made it through the week!
