Plan for Butterflies

Tiger swallowtail on native azalea (April)
Even with our mild winters in Georgia, seeing that first butterfly is always a thrill. I usually always run back inside for my camera to record the event. It’s like a flower woke up and took flight!

You might think that butterflies just happen. The truth is, you have to plant for butterflies. Therefore, you need to plan for butterflies. The monarch butterfly’s troubles give us a good case for discussion because a large number of people are familiar with its reproductive needs.

Butterflies (and their more numerous relatives the moths) live out their cycle first as eggs and caterpillars and then become amazing flying machines. Caterpillars eat leaves and the adult females will only lay their eggs on just the right kind of plant. In the case of the monarch butterfly, that plant is milkweed (Asclepias sp.). If all the milkweed were to disappear, the monarch butterfly would become extinct. In fact, there are fewer monarches today in part because there is less milkweed in the wild than before.

Therefore, if you want butterflies, you need to provide the adults with plants on which they can lay their eggs. Lots of people plant butterfly gardens full of beautiful non-native flowers for them to feast on, but without sufficient host plants for the eggs, it’s like a nice cocktail bar … only there for adults. (For those of you adding parsley and fennel to your garden, that only supports 1-2 common butterfly species.)

How do you plan for butterflies? I take two approaches. First, I see what butterflies are already in my area by observing them in my yard or on my walks around the neighborhood and surrounding wild areas. For those butterflies, I want to make sure that I know what host plants they need and try to keep providing those plants in my yard.

Butterflies (and host plant examples) already around me include: Eastern tiger swallowtail (tuliptree, black cherry), red-spotted purple (black cherry, hawthorn), spicebush swallowtail (spicebush, sassafras), American lady (pussytoes, rabbit tobacco), buckeye (Ruellia, Agalinis), Gulf fritillary (passionvine), monarch (milkweed), and the many butterflies that host on plants in the pea family: cloudless sulphur and sleepy orange (partridge pea), long tailed-skipper (hogpeanut, Desmodium, silver-spotted skipper (false indigo), and Eastern tailed blue (Lespedeza).

Second, I research other common butterflies (or ones that other people near me mention) and work on adding to my yard the plants that they need for their caterpillars; the plants they need are native to my area but were probably culled out by humans before me. For example, the red admiral, comma, and question mark butterflies need false nettle (Boehmeria cylindrica) as a host plant, so I ordered some seeds for it. I recently added pipevine in the hopes of attracting a pipevine swallowtail. I have juniper but I’ve yet to see a Juniper hairstreak.

Red-banded hairstreak on Eupatorium
Sometimes new butterflies surprise me. In 2016, 4 new ones showed up: red-banded hairstreak, viceroy, gemmed satyr, and great spangled fritillary. Of those new ones, I don’t have host plants for the viceroy but I believe someone down the street has a willow (Salix). Willows are actually pretty common in wild wet areas but people don’t usually notice them. In my caterpillar searching, I found the caterpillar of the luna moth on sweetgum in the backyard, but I’ve not seen the adult.

It’s important to do your research and keep your eyes open. That’s one thing I learned during my caterpillar search last year; even if you don’t notice them, they’re out there. The more diverse selection of native plants that you have, the more butterflies you’ll have. Plan for it.

As Lovely As a Tree

Liriodendron tulipifera
The third Friday in February is Georgia Arbor Day. It is a good day to plant a tree in Georgia because we generally have mild conditions and can usually dig a hole even in winter.

It is also a good day to remind ourselves why trees should be planted. This is a tuliptree (Liriodendron tulipifera). It provides food for several kinds of birds and small mammals. It is one of the host plants for the Eastern tiger swallowtail butterfly (state butterfly of Georgia). For humans, it provides shade, beauty, erosion control, and oxygen.


The title for this post references a poem by Joyce Kilmer entitled “Trees,” written in 1914. It's a wonderful poem for feeling good about trees. The well-known first couplet is:

I think that I shall never see
A poem lovely as a tree


The Arbor Day movement itself, of course, seeks to encourage people to plant more trees. The first Arbor Day in the United States was celebrated in 1872 by Sterling Morton in Nebraska. It was picked up nationally in 1907 thanks to a proclamation by Theodore Roosevelt with a focus on educating school children about conservation. Helping school children learn more about the importance of trees is a very fun and rewarding experience, but it’s never too late to learn about why having trees is so important.

butterflies and moths

Trees have nourished and inspired men for generations, every year enrapturing new people with their beauty, utility, or life-giving resources. I am proud to be a “tree-hugger” and seek to inspire others to love trees as well. I hope you will take this opportunity to consider the importance of trees to our ecosystem, especially native trees.

Here are some of my Arbor Day posts from previous years:

Bird’s Eye View

American goldfinch
Sometimes we look at our yard from a neighbor’s perspective – is it neat and attractive? When you’re a nature lover, you might consider a different view point. How about from an insect’s perspective or a bird’s?

What are insects and birds looking for when they come by? We’ll have to imagine that we are such a creature, but it won’t take much imagination actually. We know that birds and insects need the essentials: food, water, shelter, and a place to raise their young. The important thing to understand that across the thousands of different types that pass through our yard, their needs vary quite a bit.

Food and Water

A low estimate of the number of bird species that pass through my yard would be 50. Some of them are frugivores, some are granivores, hummingbirds are nectivores, and then many of them are insectivores (or need insects for their chicks). They all don’t eat the same thing.

Ambush bug eats skipper
The number of insect species is even higher. Some of them are herbivores (eating plants: leaves, pollen, or nectar) while others are carnivores (eating other insects).

Within those two broad categories, insects are often specialists on certain plants (think monarch butterfly caterpillars eating milkweed, Asclepias sp.) or certain prey. For example, a small insect can eat a mosquito but it takes a larger one to eat a fly.

In addition to birds and insects, of course, we also have lizards, turtles, and other critters and they have needs too. When you’re looking at your yard, do you have enough diversity to provide for the creatures that are thinking about living/eating there?

Shelter

Shelter needs are every bit as varied as food needs. There are the obvious bird considerations: nest boxes, dense shrubs, tall trees. Birds that are winter residents need thick vegetation during cold nights.

Critters need a place to go too when they are resting. They will hide out on all types of plants: leafy perennials, shrubs, and trees.

Insects will also take shelter in dead leaves, under loose bark, and in the soil. If a mowed lawn is our predominant vegetation, how helpful is that to insects?





Place to raise their young

Some critters actively manage their young (like birds) while others lay eggs and leave. Some (like bees) lay eggs with provisions and leave.

(the anole safely exited the web later)

Birds build nests in varied places: some nest on the ground, in brush, and in the cavities of dead and living trees. Eastern phoebes will make nests on manmade ledges (like my security lights). During active bird nesting season you can help by watching out for predators. We lost a whole nest of baby bluebirds because a snake got into the nest box and ate them. We now have a snake guard on that box.

So if you’re interested in attracting wildlife, look at your yard from a critter’s point of view. Maybe that tidy sweep of grass won’t look so good after all!

Can I Get a G-E-O-R-G-I-A?

Several years ago I came up with an idea to create the picture shown here. It would spell Georgia and contain pictures of indigenous plants in each of the letters to show how beautiful and unique Georgia’s native plants can be. I finally came across a tutorial for my favorite picture editing software that explained how to do it. Thanks to James for enhancing it with a bold outline.



I decided to feature pictures in seasonal order (because I am all about being seasonal!) so the first plant listed is a spring bloomer and the last one listed is what you can find at the end of the year. Unfortunately, the hardest part was deciding which plants to use and limiting myself to seven pictures! Here are the picture contents:

G – early spring-blooming bloodroot (Sanguinaria canadensis)

E – mid-spring flowering eastern columbine (Aquilegia canadensis)

O – blueberries that ripen in June (Vaccinium sp.)

R – summer-blooming phlox (Phlox carolina) with syrphid fly

G – fall-blooming Georgia aster (Symphyotrichum georgianum) and Stone Mountain daisy (Helianthus porteri)

I – the fall foliage of chalk maple (Acer leucoderme)

A – the fruit of American holly (Ilex opaca)


I hope this graphic will help peak more interest in our beautiful Georgia flora. Feel free to share the picture!

Hard Labor Creek State Park

Every year I try to visit more Georgia State Parks. I even bought an annual pass in 2016 to make it more economical, but I’m afraid that I let other things get in the way. During December I usually have extra vacation and try to convince others to go. This year I talked my daughter and husband into going to Hard Labor Creek State Park in Rutledge, GA, not far from I-20.

This is a large state park (5804 acres) and it contains walking trails, bike trails, and equestrian trails. You are allowed to walk on the equestrian trails so we planned to walk at least part of the Lake Rutledge trail (we did about 5 miles of the total 16). The park contains two lakes and Hard Labor Creek flows between them.

Before we had a chance to even find the trailhead, a flash of movement caught my eye in the parking lot. Rustling in the fallen hardwood leaves was an armadillo, searching for insects in the rich soil. I had always wanted to see one, so we took a few minutes to take his picture.

Our first creek crossing was a little tricky
Who you looking at?


















The park is a beautiful deciduous forest in the Piedmont ecoregion, much like my own place. A study of the different fallen leaves during the hike found at least 6 oak species (white, red, southern red, post oak and likely both scarlet and black), several hickories, sourwood, several maples, musclewood, American beech, sweetgum, and American holly as well as numerous pines.


American beech (light tan) and chalk maple (dark tan)
This trail was a good place to see several good examples of marcescence, the characteristic of dead leaves remaining on the tree. The trees we saw with this characteristic were American beech (Fagus grandifolia), chalk maple (Acer leucoderme), and musclewood (Carpinus caroliniana) as well as several young oaks. In some places, there were large sweeps of each kind of tree adjoining each other, and each species had a slightly different shade of tan.

Christmas ferns sloping down to mountain laurel

Virginia sweetspire (Itea virginica)
In the area where the trail was beside Hard Labor Creek, steep slopes were populated with Christmas ferns (Polystichum acrostichoides) and thick stands of mountain laurel (Kalmia latifolia). I wanted to get to the creek but there was no way down. The trail flattened out where it reached the shore of Lake Rutledge and there we saw our second armadillo, diligently rooting through the leaves again. The shore area was populated with tag alder (Alnus serrulata) and Virginia sweetspire (Itea virginica).

Onward we went, following horse poop and hoof prints through the forest. I was happy to see lots of sparkleberry (Vaccinium arboreum) and the plants were still showing some great color. In some areas, the trees around were thick and overgrown.  We did pass one open area that was full of Indian woodoats (Chasmanthium latifolium), and I remembered that it can be aggressive but the seed heads were very attractive in such a group. Some of the evergreen plants we saw besides Christmas fern included ginger (Hexastylis arifolia), resurrection fern (Pleopeltis polypodioides) yuccas (Yucca filamentosa) were noticeable in the woods too.

Mistle (Phoradendron leucarpum) with fruit

After we finished our hike, we went into Rutledge for some ice cream at The Caboose. On our way back to I-20, we passed a parking lot full of old Bradford pears that were almost green with mistletoe (Phoradendron leucarpum). I swung the car into the lot and took some pictures since the plants were full of beautiful berries.

The Seeds of Winter

Hibiscus coccineus
Before last week’s snow event, I walked around the yard to see what was happening in the garden. Most plants were brown, either dead above ground (herbaceous perennials) or dormant for the season (shrubs and trees). Even in these still-life poses, many offer up a promise of things to come: their seeds.

Most of these are non-fleshy seeds and they wait in their capsules or seedheads for one of the agents of dispersal to send them on their way: wind, water, and wildlife. I noticed that the capsules on the swamp hibiscus (Hibiscus coccineus) close up when wet and open wide when dry. Pine cones do this as well. I imagine they’ve evolved over time to adapt a strategy that works best for dispersal. The hibiscus seeds look like an offering of candy in a bowl, just waiting for a bird to come by and have a few.

Some seedheads are puffy, each seed equipped with its own bit of fluff to carry it away. I think of these plants as hedging their bets: the puffiness alerts birds that the seeds are ripe and ready, but if the birds fall to notice them then the wind can be the means on which they travel. Some members of the Asteraceae family employ this technique but not all of them.

before being eaten.


















The black-eyed Susans (Rudbeckia), rosinweeds (Silphium), sunflowers (Helianthus) and coneflowers (Echinacea) are three members of the Asteraceae family that keep their seeds tightly held in the dried flowerhead. If you’re cleaning seed, they are hard to get out! Birds are required to pry the tasty seeds out (and of course they are pretty good at it by now).

While I enjoy watching the birds at the bird feeder, I’m also happy to know that these seeds are available for them too. I do occasionally startle a pair of goldfinches feeding among the dry stems (never when I have the camera, of course).

Nature has been providing for them for thousands of years in this fashion, and I’m happy that my garden can contribute.

Resolutions 2.0

Often we make resolutions for ourselves at the start of each New Year: lose weight, drink less soda, take vitamins more often, eat more fresh vegetables …. We all have these, right? I was reading an essay (“Ecosystems at Our Doorsteps”) in The Xerces Society Wings magazine (Fall 2016 edition) and it occurred to me – we should make some resolutions that benefit the other critters on Earth. So here’s my take on some improved resolutions; let’s call it Resolutions 2.0.

Male bumblebee

We have the power to make a difference in our own yard (back and front!). The choices that we make can help or harm all that live in this area: bees, butterflies, birds and even other humans.

Are we using pesticides that harm insects or lawn chemicals that affect any animal that walks across the grass? Are we polluting the air with fumes and noise from leaf blowers (when we could be burning calories by raking and sweeping)? Are we providing good sources of pollen, nectar and fruit/seeds?




So be it resolved:


  1. I will protect pollinators by not using pesticides in the yard. Bees will be free to gather pollen and nectar that has not been altered by pesticides like neonicotinoids and others. In addition, other bugs will be safe from unintended harm caused by spraying of pesticides designed for one bug (such as mosquito treatments) but which kill others too.
  2. I will be aware that bees and other insects need a place to live. Many bees are solitary and nest in the ground (need some bare patches) or in wood like tree bark and dead branches/trees. I will use this awareness to leave room for nesting. I will be aware that butterflies and moths need a place to pupate – in a chrysalis or a cocoon or even over the winter in dead leaves.
  3. I will allow the balance of nature to control pests such as other insects or birds that eat them. I may choose to selectively deter pests by spraying them with water from the hose or hand-picking bugs like Japanese beetles and dropping them into a bucket of non-toxic but lethal soapy water.
Blue mistflower (Conoclinium coelestinum) is always a winner in the fall; common checkered skipper agrees

  1. I will plant flowers with abundant pollen and nectar for insects. I can use three lists that I put together in 2014 for spring, summer, and fall. These lists will give me plenty of ideas of what to add to my garden for this goal.
  2. I must remember to buy them from places that didn’t treat them with pesticides while they were growing them.
  3. I can plant with wildlife in mind. When choosing what plants should be in my yard (either as new or as replacements for non-native plants), I can be more aware of what benefits each plant brings to the greater ecosystem (not what just brings me pretty flowers).
The work of small bees on this butterfly milkweed (Asclepias tuberosa) resulted in many seed pods

  1. Butterfly gardening is more than colorful flowers. I can choose plants that provide multiple benefits: not just floral rewards (nectar and pollen) but those which also are host plants. For example, milkweed (Asclepias) is a great nectar plant (my bees love it) but it is also a host plant for butterflies such as the monarch. If you have a small garden, learning about plants that support both roles means you can do more with a smaller space.
  2. I can increase my overall plant diversity to help more insects. There are hundreds of butterflies, thousands of native bees, and even more thousands of native moths and many of them have special plant relationships. Without their special plant being available, the insect cannot remain in that area. There’s no value to planting the same thing as everyone else and planting large groups of the same thing.
  3. I can look for regionally appropriate plants to make sure local insects get the support they need. For example, while I love Florida anise (Illicium floridanum), its native range is nowhere near me; it is native to the southeast Coastal Plain where Georgia adjoins Florida. Therefore, I recognize that having it in my landscape is not much different than having a plant from another country.
