A JULY VISITOR DISCOVERS THE HAPPY DUNG BEETLE
This morning I awoke before everyone else in the house and decided
to walk across the island through the forest to the
beach.
In my early morning half sleep I had confused the
snuffling sounds in the leaves outside my window before dawn for
a very large armadillo. Dreaming, I thought the armadillo, which,
like myself, is a fairly recent inhabitant on the island, had lost
his way and was searching for a path across the yard to the pool
of fresh water hidden in the tall grasses behind the house. I could
tell by his frantic scuffling sounds he was a very thirsty armadillo.
But when I was awake enough to open the white wooden shutters and
peer into the departing dark, I realized this was not an awkward,
lost armadillo, but a lanky feral bay mare pawing in the sand and
leaves, looking for a bite of green under my window. Breakfast time
on the island.
I drank licorice tea and grabbed a peach and headed
out the back door across the sandy path. But as often happens on
Cumberland, I did not get very far before something strange and
beautiful caught my eye and completely thwarted my plans. About
a hundred yards from the house I came upon what appeared to be a
living pile of fresh horse manure. The dark green mound was literally
heaving and looked as if it would pick itself up and move across
the road into the forest.
The gray morning light lightened the path, and the
closer I got the better I could see that this was not some strange
blob of ectoplasm making its way across the road, but a normal pile
of old-fashioned horse manure that was being transformed by that
happiest of creatures, the dung beetle.
I knelt down and observed about twenty of the small
black creatures hard at work sculpting tiny mini balls of manure
out of the larger pile. Each beetle was utterly intent on its own
project, oblivious to its neighbor performing the exact same task.
Using its pincers and back legs, each beetle molded a perfectly
round tiny ball of manure about the size of a large marble. This
took about five minutes of uninterrupted effort. Then, the beetle
would head off in the direction of the pine needle blanket on the
forest floor, rolling its ball ahead of it like some tiny circus
performer. Occasionally, the beetle would stop and lift his treasure
high above his head and wave it around as if to say, ”Look, see
what I can do! How perfect is this work of art!” The ball of manure
was so perfectly rounded that each artisan could roll it several yards
into the peace and quiet of the shade, out of harm’s way.
Once in a spot three to five feet away, and nestled
safely down in the pine needles and dry leaves, the beetles would
rest on their cool balls and eventually lay their eggs. Like mud
daubers that lay their eggs in little compartments packed with dead
insects, the new larvae would be born into the world with a meal
immediately accessible.
I don’t know how long I stood there, but my walk
to the beach was completely forgotten in this mysterious and beautiful
adventure. Is this perhaps the same creature that the eighteenth-century
British naturalist-artist Mark Catesby refers to as the
Tumble Turd? If so, what a perfect name.
