BACKYARD SECRET – HOW MUCH NECTAR DOES AN ADULT E. TIGER SWALLOW EAT IN A DAY?

Aug19

         The Eastern Tiger Swallowtail is one of the largest butterflies commonly seen in Georgia yards.  In spite of its relatively large size (wingspan -3.5 – 5.5 inches), this colorful butterfly consumes only 0.0014 – 0.0105 ounces of nectar daily.  To put this in perspective, a standard-sized paperclip weighs only 0.04 ounces.

BACKYARD SECRET – SILVER-SPOTTED SKIPPERS SHUN YELLOW FLOWERS

Jul30

       Sometimes a wildlife secret hides in plain sight.  A good example of that is, in spite of the fact that the silver-spotted skipper visits gardens across Georgia; it is not generally known that this handsome butterfly shuns yellow flowers. While the silver-spotted skipper occasionally nectars at yellow flowers, it by far prefers feeding at purple, red, blue and pink blossoms.

       If you want to see if this is true, closely watch which flowers silver-spotted skippers visit in your flower gardens this summer.

CONFLOWERS – A GREAT ADDITION TO YOUR GARDEN

Jun21

       One of our favorite garden plants is a native called purple coneflower (Echinacea purpurea). 

       This native perennial is a magnet for butterflies, bumblebees and other pollinators. In addition, its seeds devoured by a number of birds such as sparrows, eastern towhees, nuthatches, Carolina chickadees, tufted titmice, and northern cardinals.

       One of things I like best about the plant is that it blooms from May until September.

       While it will make a great addition to most Georgia flower gardens, when you purchase purple coneflower plants you need to know if you are buying true native coneflowers or one the many cultivars on the market.  These plants bear fanciful names such as Secret Affair, Avalanche, Coconut Lime, cotton candy, Fatal Attraction, Lilliput, Meringue, and milkshake.

       While these variety might be of value to wildlife, far too often cultivars are showy but lack the ability to produce nectar, pollen and seeds.  I can attest to the value of native purple coneflower, however, I know nothing about any of the cultivars sold in nurseries across the state.

       If you have found any of the cultivars of value to wildlife, please let me know.

 

 

BACKYARD SECRET-WEBSITE THAT PROVIDES INFORMATION ON NATIVE PLANTS IN YOUR AREA

Apr23

       The number and variety of native plants that grow in your yard plays a key role on determining what species of wildlife will inhabit your yard. The problem is trying to determine which plants will grow in your neck of the woods.

       The National Audubon Society has simplified the task of trying to identify which native wildlife-friendly plants grow in the county where you live.

       If you want to access this information, go to the National Audubon Society’s website.  Once there scroll to the window labeled Plants that Grow in your Area.  You will see a place where you enter your zip code.  Type in your zip code; press the Enter button and the plant list for your area will appear.

BACKYARD SECRET – PLANTING GROUPS OF PLANTS BENEFIT HUMMINGBIRDS AND OTHER POLLINATORS

Apr1

     

        If you are looking for a simple way to benefit hummingbirds, butterflies and other pollinators, plant nectar plants in groups of the kind.  You will find that mass plantings enhance the beauty of your yard and makes it easier for these valuable backyard neighbors to locate plants bearing nectar. 

       With that in mind, plant no less than 3-5 of the same variety together.  If have enough room for larger plantings, masses of plants measuring two to three are even better.

       I hope you will try this simple technique this year.  I suspect that, if you take this advice, the pollinators will love it and you will wonder why you have not adopted this gardening trip before.

BACKYARD SECRET – BUTTERFLIES ARE SOMETIMES SMALLER IN THE SPRING

Mar23

       Recently my wife and I were walking about our backyard on a recent March after noon we noticed that one of our native azaleas was in full bloom.  When we stopped to admire the beautiful blossoms displayed by the large native azalea, an eastern tiger swallowtail flew in and began nectaring at the shrub’s stunning blooms.  As we watched the butterfly feed, we both noticed that it was much smaller than the tigers we normally encounter.  This begged the question, “Why is this individual so small?”

       One possible reason for this is eastern tiger swallowtails overwinter as pupae in a chrysalis.  If a butterfly emerges earlier than normal due to unseasonably warm weather, it may be smaller because it pupated before reaching its normal size.

CAMELLIAS HELP WINTERING HUMMINGBIRDS SURVIVE DURING GEORGIA WINTERS

Dec4

       It is easy to believe that winter hummingbirds are totally dependent on our feeders to survive.  Although feeders hanging in backyards have helped hummingbirds winter throughout the Southeast, wintering hummers such as the rufous have other sources of food.

       One of these foods is the sap that wells up in active sapsucker holes.  Although yellow-bellied sapsuckers excavate these shall reservoirs to provide food for themselves, a variety of critters such as other birds, squirrels, butterflies and even hummingbirds dine on the sugary sap found their excavations. Since the shrub also produces pollen, they attract the some of the few pollinators that also dine on pollen during the winter.

       Another underappreciated source of food is the nectar is produced by winter blooming camellias. One of the best is (Camellia sasanqua).  This flowering shrub blooms from fall throughout the winter.

       These glossy-leaved thick shrubs also provide the tiny birds with much-needed roost sites.
If you know of any other varieties of camellias that attract winter hummingbirds to your yard, please let me know.

AFTER FREEZE NECTAR SOURCES

Nov16

       This week much of Georgia suffered through the first freezing temperatures of the season.  At our home in Monroe County, the temperature fell to 27º.   Realizing that spelled trouble for many pollinators my wife and I brought in two plants (scarlet sage and pineapple sage) that have been hosting cloudless sulphurs for the past few weeks.

       When the weather returned to normal, we put them back on our deck. In a matter of minutes, they were once again being visited by cloudless sulphurs, syrphid, and hover flies. While our efforts did not benefit many pollinators, they did provide a few with much-needed food. In addition, we extended the time we can enjoy watching pollinators at work in our yard.
Based on our success I decided to visit our local nursery (Mossy Creek) to see if any of their plants had survived the cold and were hosting pollinators. 

       I no sooner got out the door of my vehicle when one of the nursery’s staff called me over to look at a stunningly beautiful butterfly. The butterfly turned out to be a zebra longwing; it was the first I have seen this year.  The whole time that I was there, the butterfly fed at lavender pincushion blossoms.

       While I watched, an American lady joined it.  Nearby, an Ocola and fiery skippers, and a couple of American ladies visited marigolds.  All of these plants had survived the severely cold weather.

       Later, our daughter told us that a hover fly was feeding on a late four-o’clock bloom beside her house.  She also saw several pollinators visiting coneflowers at a nursery in Columbia County.

       Admittedly, the weather was not kind to our gardens this year consequently; we did not have many sources of nectar available deep into the fall.  However, we pledge to do better next year.

       If you want to help late pollinators in your yard, the first thing you need to do is find out which pollinator plants can survive cold weather in your neighborhood.  One great place to learn find this information is your local nursery.  There is no better time do so than after our recent freeze.  Armed with this knowledge you will be better able to address the food needs of the pollinators living close by.

       When I returned home, I was carrying four pots containing cold-hardy plants that we are going to add to our yard. 

      

DEAD LEAVES ARE IMPORTANT TO MANY MOTHS AND BUTTERFLIES

Oct19

       Most of us do not enjoy raking fallen leaves in autumn, however, not raking leaves around butterfly and other host plants is one of the most important ways to ensure you will see your favorite butterflies and moths flying about your yard next year. 

       A beautiful day-flying moth, the snowberry clearwing, is a great example of a moth that benefits from not raking leaves beneath its host plants.

      The snowberry clearwing is a day-flying moth that frequents our flower gardens during the summer.  This stunning moth uses a handful of plants as its larval host; one such plant is coral honeysuckle.  This native honeysuckle bears long red tubular flowers throughout the spring and summer. After the moth’s bright green caterpillars have grown as big as they are going to get, they literally drop to the ground beneath their hosts and hide among the fallen leaves.  They then enter the next stage of their life; forming a cocoon and pupate during the winter.  This miraculous process only works if the caterpillars fall into a protective blanket of leaf litter.

       Other moths and butterflies also spend the winter in leaf litter.  With that in mind, when we refrain from raking the leaves under host plants, we benefit the moths and butterflies wintering among these fallen leaves too.

BACKYARD SECRET – WHAT IS THE BEST TIME TO SEE MONARCHS IN GEORGIA DURING THEIR FALL MIGRATION?

Oct15

  

     

 

        The best time to catch a glimpse of fall migrating monarch butterflies is during the months of September and October.    Records, however, suggest the greatest number of these butterflies pass through the state in mid-October.       

       With that in mind, if you want to see these large orange and black butterflies, spend some time outside during the next few days.

       Good luck!
