With spring just weeks away, there is no better time than now to decide which plants you are going to introduce into your home landscape this growing season. With that in mind, if you are looking for a native plant that is beautiful and is a used by pollinators such as ruby-throated hummingbirds, butterflies and others, consider planting beebalm. Here is some information that you should consider when deciding whether or not you want this native wildflower in your yard.
Wild Bergamot (Beebalm) – Monarda fistula – Type of Plant – perennial; Height – 1 to 5 feet: Blooms – June to September; Soil – moist to well drained; Light – full sun to partial shade; Wildlife Use – butterflies, songbirds, hummingbirds.
Early last week the overnight temperature dropped to 24˚F. As expected, the hard freeze changed the complexion of my backyard. Prior to the frigid weather a dozen or so plants were still blooming. They were providing wild pollinators with a much-needed source of nutrition.
The only flowering plants that survived the cold weather were sweet alyssum, blanket flower, and sasanqua. Although most of the flowers on my butterfly bushes died, remarkably a few survived too.
However, some did survive and are visiting the meager array of blossoms that remain. The only insects I have seen lately are yellow jackets, bumblebees, and cloudless sulphur butterflies.
The yellow jackets have continued to feed on the sugar water found around the feeding portals of a couple of hummingbird feeders that are being maintained in hopes they will attract a rare winter hummingbird.
Tiny native pollinators have focused their attention on the tiny blossoms adorning sweet alyssum encircling a backyard birdbath. Two or three cloudless sulphurs and a couple of bumblebees are regularly spotted visiting butterfly bush, sasanqua and blanket flower blossoms. When they are gone, I will give my full attention to the animals that inhabit my backyard throughout the winter.
Indeed Mother Nature provides those of us willing to watch and listen great wildlife viewing opportunities throughout every season of the year.
Today I awoke to a thermometer reading of 32˚F. This marks the first day the temperature has plummeted to the freezing mark this fall. While I do not have any idea how long the temperature hovered this low, I know it could not have been too long since none of the plants flowering in my backyard showed any signs of frost damage.
When I ventured outside for the first time on this sunny, cool day the temperature had risen to 57˚. Much to my surprise the first creature I saw this morning was a monarch butterfly. The monarch was nectaring on the purple blossoms displayed on two butterfly bushes.
Needless to say, I was startled to see a monarch on such a cold morning since even on a sunny day, monarchs are rarely seen when the air temperature is in the 50s. When it is cloudy, this magnificent butterfly often does not take to the air until the air temperature reaches 60˚. That being the case how was this butterfly out and about feeding?
In autumn, when monarchs are passing through the south on their way to Mexico they seem to prefer to roost in pecan and oak trees; especially those growing close to a nearby source of nectar. These trees offer protection from the wind and their dense foliage provide places to roost that at are often warmer than the air temperature.
During the past few years, I have noticed that late in the afternoon during the monarch migration, monarchs will nectar on one particular butterfly bush growing on the north side of my home. Just beyond my driveway stand three water oaks. Several times as the sunlight melted away, the monarchs would flutter up into the oaks and vanish from sight. While I am not positive this is their nighttime roost, I suspect it is.
Wherever the monarch I saw this morning roosted, it could not move until the temperature rose above 40˚. As the temperature slowly climbed, the butterfly had to crawl to a sunny spot and open its wings and bask in the warming rays of the sun. The butterfly’s black scales and abdomen enabled to it to absorb the heat needed to raise its body temperature. Once its flight muscles reached 55˚ degrees, the monarch was capable of flight.
I am certain the monarch I saw this morning is now miles away from my backyard. As the sun begins to dip below the horizon this afternoon, I hope it finds another suitable roost site and the night will not be as chilly as it was last night in Monroe County.
One event that backyard wildlife enthusiasts look forward to each autumn is the migration of the monarch butterfly. During the fall of the year, these beautiful butterflies stop and feed in our backyards as they make their way to their winter home in Mexico. This epic flight takes a tremendous toll on these gossamer-winged insects.
Ever since it became apparent monarch populations have plummeted to a fraction of what they once were, researchers have been scrambling to learn as much as they can about this fascinating insect. The results of one such study recently conducted by University of Georgia, Odum School of Ecology researchers provide us with answers as to why female monarchs are better fliers.
When the UGA research team compared the wings of male and female monarchs, they discovered some notable differences. It seems the females’ wings are thicker, and somewhat smaller. In addition, their flight muscles are smaller and lighter.
One might think having larger and heavier wing muscles, coupled with thinner and lighter wings would benefit the males. Actually, the reverse is true. The males’ larger and thinner wings are more susceptible to damage. Their wings also forced to bear more weight per square inch than those of the females.
In essence, this means female monarchs are more efficient fliers than males. This, in turn, enhances the chances of the females surviving the autumn migration.
When I posted a blog concerning the value of crepe myrtle to wildlife, a blogger posed her concern that I had wrongfully maligned this popular ornamental, and wondered what the basis of my opinion was.
It seems when crepe myrtle is blooming in her yard bees converge on the plant’s colorful flowers. She went on the say that when she deadheads the first crop of blooms to encourage a second blooming, when a new crop of blossoms bursts forth the bees return to once again feast.
To say the least, I was surprised to learn that the bees in her backyard are drawn to crepe myrtle blossoms in large numbers. The crepe myrtles that grow in my neck of the woods are rarely visited by bees. This could be explained by the fact that she grows varieties such as Lipan, Tuscarora, and Dynamite. I am not familiar with them; they may produce an abundance of pollen and/or nectar. I do not know the name of the crepe myrtle rooted in my yard; however, I am sure it does not produce much of value to pollinators. I have seen wild pollinators feeding on the honeydew secreted by the aphids that live on the plants.
I should also mention I have seen American goldfinches eat crepe myrtle seeds.
In addition to producing little food, crepe myrtle is an exotic plant is invasive in many sections of Georgia. When it “walks away” from the place where it is planted, it can usurp habitat originally occupied by native plants. Typically, the native plants it supplants are of more value to wildlife than exotics.
I am not the only wildlife biologist that does not consider crepe myrtle to be a great wildlife plant. Here is what Dr. Doug Tallamy, professor and chair of the University of Delaware’s Department of Entomology and Wildlife Ecology, has to say about crepe myrtle, “Crepe myrtle is an enormously popular landscape plant because it has a nice habit, beautiful flowers, and lovely bark. But it contribute almost nothing to the food webs in your garden. If every plant is your yard were a crepe myrtle, you would have no food webs, and, thus, no birds, butterflies or other beneficial wildlife”
If you enjoy the beauty offered by crepe myrtles in your yard, and the varieties you plant provide bees and other wildlife with food, continue to cultivate them. Meanwhile, plant some native plants that evolved alongside the native pollinators and other wildlife in your area. If you do, I think you will find they will be of great value to your backyard wildlife neighbors. In addition, you will be contributing to restoring the natural ecology of your yard.
The long-tailed skipper is a butterfly that can be seen in all of Georgia’s 159 counties. Although it can be seen from April into November throughout much of the state, in my backyard, I see more long-tailed skippers from late summer into the autumn than at any other time of the year. Since it is so common and seen over such an extended period, one might think all of these butterflies live and die in the Peach State. Actually, many do. However, some have wanderlust.
For reasons that are not fully understood, during the summer some long-tailed skippers take wing and move northward. These movements are particularly common along the Coastal Plain. As a result, before cold weather sets in long-tailed skippers are sometimes spotted as far north as southern New England.
Far more often, however, each fall far more long-tailed skippers will fly south to the peninsula of Florida. Here in Georgia some longtails are considered permanent residents, particularly in the southeast corner of the state.
In spring, long-tailed skipper populations in Florida begin moving northward and eventually end up in our backyard gardens.
I suspect many of the long-tailed skippers I am currently seeing in my backyard are en route to the Sunshine State. Meanwhile, for the past several weeks, long-tailed skippers are the butterflies I have most often seen visiting ageratum, butterfly bush, zinnias and other fall-blooming plants. This is the first autumn I can remember when I have seen more long-tailed skippers than cloudless sulphurs in my yard. I suspect our prolonged drought has played a role in this situation.
In the meantime, since I am not seeing any migratory songbirds in my yard, and most other butterflies such as eastern tiger swallowtails have disappeared; long-tailed skippers have added an appreciated touch of beauty to a backyard that has suffered immensely from a lack of rainfall.
Most of us have been taught that birds do not eat monarchs. In fact, if a bird just happens to try to make a meal out of a monarch, it gets sick from ingesting the poisonous compounds that course through the monarch’s body. After living through such an experience most birds do not try to dine on a monarch again.
Eastern bluebirds are an exception to the rule. These gorgeous backyard favorites eat monarch caterpillars laden with poisonous chemicals obtained when they chomp on milkweed plants without showing any ill effects.
The bluebird can devour this toxic food because it uses a technique to prepare a caterpillar before it tries to consume it. Once a bluebird grabs a monarch caterpillar it flies to a branch and squeezes the large, juicy caterpillar time and time again. This process forces much of the juicy innards of the caterpillar out both ends of its body. Once the caterpillar has been flattened, the hungry bluebird then proceeds to eat the hapless insect.
Now that September has arrived it is hard not to turn our thoughts toward fall and migration. Invariably we associate migration with birds. However, the plight of the monarch has heightened our interest in the migration of insects such as the monarch butterfly.
Each fall these amazing insects make their way south to their winter home in Mexico. While this is truly an amazing fete, we know very little about how these butterflies accomplish this seemingly impossible task. Recently the results of research conducted by Samantha Knight of the Nature Conservancy of Canada and others filled in another piece of the jigsaw puzzle of monarch migration.
The research team captured and placed tiny transmitters weighing only 300 milligrams on 43 monarch captured near the Canadian shore of Lake Huron. The devices were mounted on the insects in an attempt to track their southbound migration. Fortunately, the biologists were able to retrieve data from six of these butterflies. One of the most interesting findings was one of the monarchs flew 89 miles in a single day. They were also able to determine the monarchs winged their way south at a speed on 7.5 miles per hour. Knight later stated, “[It] was a lot faster than anyone had ever really anticipated.” She went on to comment, “They could likely go even faster without the heavy tags on them.”
The biologists also learned the butterflies flew faster when they were pushed along by a tailwind. This was demonstrated by one butterfly that was clocked flying at a bit under 18.5 miles per hour with the aid of a tailwind.
It was also discovered that monarchs flew faster in warm weather. However, the butterflies were not able to fly until the temperature reached 50˚F and flight speed dropped when the air temperature reached 73˚F.
It is definitely true the more we learn about these stunning insects the more we realize why they are so special.
Some of our most fascinating and important backyard wildlife neighbors are pollinating insects. Unfortunately, populations of many of these critters are declining. In an effort of assess the number of these pollinators across the state, the University of Georgia’s Cooperative Extension is conducting the first Georgia statewide pollinator census. The count will be held August 23 and 24, 2019.
Becky Griffin, UGA Extension school garden and pollinator census coordinator is inviting private citizens, families, clubs, school classes and other groups to cooperate.
The count is fashioned after the highly successful Great Backyard Bird Count. Consequently, whereas you do not have to be an expert in bird identification take part in the Great Backyard Bird Count, you don’t have to be able to identify the insect pollinators that visit your garden. Participants are simply asked to separate pollinators into eight groups (carpenter bees, bumble bees, honey bees, small bees, wasps, flies, butterflies/moths, and other insects. An easy to understand online guide to these insects can be downloaded from the Great Georgia Pollinator Census website (GGaPC.org).
Here is what you need to do to participate:
- Visit the Great Georgia Pollinator Census website and download the GGPC Observation Sheet. The sheet can be used to record your sightings.
- Select a single plant growing in your yard that you know attracts pollinators.
- Count the pollinators landing on the plant during a 15-minute period.
- Visit the website once more and upload the results of your count.
I sincerely hope that you become citizen scientist and participate in the state’s first-of-its-kind pollinator count. If you do, you will be helping conserve these valuable insects.
