BACKYARD SECRET – GLOWING EARTHWORMS

         Countless species of animals live in Georgia yards. However, when we think about the animals that inhabit our yards we often focus on large animals such as birds, mammals, reptiles, and insects.  However, there are far smaller creatures such as earthworms, centipedes, mites and the like, that also live out their lives just outside our door.  One of the most fascinating is an earthworm (Diplocardia longa). Like many invertebrates, it does not have an official common name; however, some simply refer it as the Hawkinsville glow worm.  However, what makes this earthworm so special is that it is one of only 37 species of luminescent earthworms known to exist worldwide.

         The reason we associate Diplocardia longa with Hawkinsville. Georgia is an American zoologist named John Penny Moore was the first to document the existence of this earthworm.  His description is based on worms first collected in Hawkinsville, Georgia in 1904.

       This is large earthworm is 11 or more inches in length and has a diameter of 0.20 inches.  The ends of its body are brown while the majority of the worm is colored salmon red.  The body is translucent which allows the animals veins to be visible.  The worm also displays a club-shaped swelling near its tail.

       What sets this earthworm apart from the vast majority of other earthworms is when the critter is disturbed a luminescent slimy substance that glows blue oozes out from its pores on the dorsal side of its body, as well as its mouth and anus.

       Biologists are unsure what role the sticky goo plays in the life of the Hawkinsville glow worm.  However, some zoologists theorize the eerie blue substance scares off potential predators such as moles.

       We know very little about the worm’s abundance, life history, and distribution. About all that is known is you have the best chance of digging one up in the sandy soils found in Georgia’s Coastal Plain.

       While I personally have never heard anyone talk about finding a Hawkinsville glow worm, I suspect that backyard gardeners throughout the region unearth it from time to time.  If you have happened across one of these odd creatures, I would love to hear about your experience.

 

DEALING WITH A SNAKE IN YOUR YARD

        Whenever we spend some time in our yards there is always the chance that we will encounter a snake.  Consequently, what is to best way to react when you do see one?

       To begin with, according to the state herpetologist for the Georgia Department of Natural Resources, Daniel Sollenberger, chances are the snake you see will not be poisonous.  The reason for this is that out of the 47 species of snakes native to Georgia only 7 are poisonous.  In addition, the copperhead is the species that is usually found in suburban areas.

       When you see a snake, here is what the Georgia Department of Natural Resources recommends that you do.

       Do not attempt to handle it. Give the reptile a wide berth. If possible, take a photo of the snake.

       If you cannot identify it, a good source of information can be located at georgiawildlife.com/georgia snakes.

       Remember, state law protects our native nonpoisonous snakes. In addition, federal law protects the eastern indigo snake.

       Since the snakes in your yard are trying to hunt down prey such as insects, small mammals, amphibians and even other snakes, they should be allowed to escape into nearby cover.  However, if you locate a potential poisonous snake that poses a potential danger to you, your family, or pets, do not try to remove it yourself.  Instead, your best course of action is to contact a private wildlife removal specialist.  You can obtain a list of them by going to georgiawildlife.com/preventing-wildlife-conflicts.

THE RABBIT MOST COMMONLY SEEN IN GEORGIA BACKYARDS

        If you live in the suburbs or a rural area, there is a good chance that rabbits appear from time to time in your backyard. However, since four species of rabbits live in Georgia, which species of rabbit inhabits your yard?  If I had to guess, I would say it is the eastern cottontail.  Here’s why.

       The Appalachian cottontail, eastern cottontail, marsh rabbit and swamp rabbit all occur in the state.  However, the rabbit most often seen in Georgia backyards is the eastern cottontail.

       Eastern cottontails are 14-17 inches long and can weigh from two to four pounds.  One of the easiest ways to identify it is to look at the color of the nape of its neck.  The eastern cottontail has a cinnamon-colored nape.  None of the other species of rabbits that inhabit the state displays this characteristic.

       Although I do not know of anybody that hosts a marsh rabbit or Appalachian cottontail, I know a couple that feeds swamp rabbits in their yard.  The swamp rabbit is our largest rabbit (3.5-6 pounds).

       The marsh rabbit is our smallest rabbit. This rabbit weighs only 2.5-3 pounds.   It lives in in the Coastal Plain and prefers marshy areas, wet bottomlands, and swamps.

       The Appalachian cottontail is our rarest rabbit.  This is because its range extends only into extreme Northeast Georgia.

THE HERCULES BEETLE IS BIG BUT NOT DANGEROUS

       Whenever you encounter the eastern Hercules beetle (Dynastes tityus), you may be astonished at it size and perhaps fear it might bite you. 

       The eastern Hercules beetle is indeed large, in fact, since it can attain a length of around 2.5 inches, it is probably the largest beetle you will see in your backyard.

       However, while it appears dangerous, it will not bite or sting.  It much prefers to eat rotting fruit or the sap exuded from ash trees than human flesh.

       Both male and female eastern Hercules beetles range in color from olive green, to tan and gray.  Their exoskeletons display multiple black spots. No two beetles have the same number and distribution of spots.  Consequently, researchers use the spots to identify individuals.

       As you can see from the photos that accompany this blog, males sport two pronotal horns that some described as looking like the horns of a rhinoceros. The males use these horns when fighting for the opportunity to mate with females.  Females lack horns.

       Although they are found throughout Georgia, the homeowners that are most apt to find one of these giant beetles are those have yards that feature scattered hardwood trees, especially those where rotten limbs have be allowed to remain on the ground.  Eastern Hercules beetle larvae feed on rotting wood, especially oak.

       Since eastern Hercules beetles are nocturnal, it is unlikely that most of us spot one unless it is drawn to an outside light.

       The strength of eastern Hercules beetles is legendary.  Perhaps that is the reason we sometimes refer to it as the ox or elephant beetle.  It is said that it can lift an object 850 times its own weight.  This is the equivalent of a human lifting nine fully-grown elephants.

       I hope you will have the opportunity to spot this gentle giant in your yard.  It represents one of the countless animals that are hiding in plain sight in our backyards.

        

LOOK FOR LEOPARDS IN YOUR BACKYARD

        From spring into fall, leopards stalk our backyards.  I am not talking about the feline variety.  I am referring to the giant leopard moth (Hypercompe scribonia).

        However, like the predator, that roams the wilds of Asia and Africa, the giant leopard moth also has spots.  The spots on its wings vary from black to blue.  Some spots might even have white centers.  Once you see one, you will have no problem understanding why we call it the leopard moth.  Nevertheless, I think you will agree with me that it would have been more appropriate to name it the Dalmatian moth.

       The female leopard moth is smaller than the male. Males have a wingspan of 3.6 inches whereas the female’s wingspan is only 2.25 inches.

       The leopard moth has a variety of host plants including male, cherry, willow, sunflower, cabbage.

       If you want to see one of these handsome moths, the best strategy you can employ is to have the moth come to you.  Fortunately, leopard moths are attracted to lights.  Armed with that tidbit of information, just pull up a lawn chair near an outside light and wait.  (Lights with shorter wavelengths work best.)  If there is a giant leopard moth nearby there is a good chance it will appear.

       When a leopard moth finally shows up chances are will be a male.  For some reason, females do not visit lights as often as the males. 

       As you might expect, some folks will attract more leopard moths than others will.  I have never been able to attract more than one leopard moth at a time to my lights, nevertheless, some homeowners report seeing upwards of a dozen or more.

          

THE DANGER POSED BY COPPERHEADS IN GEORGIA YARDS

       The chances of finding a poisonous snake in a Georgia backyard are low.  However, if one does appear, throughout most of the state, it will be a copperhead. One reason for this is the snake is ranges throughout the Peach State except in that portion of the southeastern Coastal Plain below the Altamaha River.  Another reason is copperheads appear to be more tolerant of human development than other species of poisonous snakes.

       While nobody ever wants to find a poisonous snake in their yard, if one does appear, probably the one that you want to see is the copperhead.  It is not an aggressive snake.  As such, more often than not, copperheads will only strike when they are disturbed or folks try to pick them up.

       Unfortunately, copperheads do bite humans. An average of 2,920 copperhead bites occurs annually. The good news is, since copperhead venom is the least potent of any poisonous snake found in North America, copperhead bites are rarely life-threatening.  In fact, only 0.01 percent of these bites are fatal.

 

 

BACKYARD SECRET—THE GRAY SQUIRREL’S FRONT TEETH NEVER STOP GROWING

        A gray squirrel’s front teeth are constantly being worn down. If this was not the case, they would quickly wear down and lead to the animal’s premature death.  This fate is prevented because they are constantly growing at a rate of approximately six inches per year.

BACKYARD SECRET—CPT. JOHN SMITH NAMED THE OPOSSUM

     Captain John Smith, a leader of the Jamestown Colony, is widely credited with naming the opossum. 

     Supposedly, Captain Smith came across an opossum while in the company of a member of the Algonquin Tribe.  When Smith asked the man what this strange looking animal was called, his companion told him it was an “aposum.”  The Native American name referred to the long-tailed animal’s white face.  However, as luck would have it, as the man uttered the word “aposum” he grunted.  This led Captain Smith to believe he said possum.  Is this story true?  We may never know for sure.  What I do know is the opossum is indeed an odd animal.

THE FROGLOG CAN SAVE THE LIVES OF WILDLIFE IN YOUR YOUR BACKYARD

        Each year untold numbers of frogs, toads, bats, rabbits, birds, chipmunks and other wildlife species are trapped in swimming pools and decorative water features with sides that are simply too steep for the animals to crawl to safety.  If they are lucky, they will be spotted by someone that can gently remove them from the water with long-handled net. However, in far too many instances the animals swim around until they become exhausted and drown.

       This past week, during a visit to the River Banks Botanical Garden in Columbia, South Carolina, my granddaughter, Anna, and her friends stumbled across a simple device that was being used to avoid such tragedies.  It seems they found 25+ toads mating in a pool surrounding a decorative fountain. Since the edge of the concrete pool was extremely steep, it was obvious the adult toads had little chance of climbing out of the pool after the female toads laid long gelatinous strings of eggs and the males fertilized them.

       In an effort to prevent the toads from drowning, several FrogLogs had been positioned along the edge of the pool.  The FrogLog is a simple device that serves as an exit ramp leading from water to dry land. If they are left in place after the adult toads hop to safety, they will serve as exit ramps for a new generation of toads.

       That is amazing when you consider the FrogLog consists of nothing more than an inflatable floating platform and fabric bag attached to a nylon mesh ramp.

       If you have a problem with animals becoming stranded in your pool, this might be a simple solution to a perplexing problem.

IT IS TIME TO REMOVE VINES AND TALL PLANTS GROWING NEAR NESTING BOXES

        Before we know it, spring will be here, and birds will be nesting in the nesting boxes we have erected for them.  Among the chores we all need to tackle in preparation for this year’s nesting season is trim back the vines, saplings and shrubs growing close to each of our nesting boxes.

       One of the main reasons why this should be done is it helps protect the birds nesting in our boxes from arboreal snakes (those that climb trees).  Snakes such as the rat snake are capable raiding nesting boxes erected on poles.  For that reason, it is always best to mount nesting boxes on poles equipped with predator guards.  However, even the best predator guards cannot protect a nest if vines encircle the pole or tall vegetation is growing nearby.  Such plants create a veritable superhighway for snakes trying to raid a nesting box.  Even if vegetation is not actually touching a box or pole, a snake can circumvent a predator guard and gain access to adults, eggs and/or young birds by simply climbing up nearby vegetation and then extending their body the distance between their head and the box.

       For this reason, we need to make every effort to cut back tall vegetation in a wide circle around each nest. While we are creating this protection zone, any branches growing close to the top of the box should also be trimmed away.  Snakes are also capable of using a canopy of branches to gain access to a nesting box.

       Taking a little time to perform this simple task can give the birds nesting in our boxes a better chance of being successful.
