Southern Pine Snake Stands Its Ground!

When Anne and I walked on the sidewalk near Lake Tsala Apopka here in Florida, a woman cautioned us about a snake on the walkway ahead. When we were on Long Island in New York, we would never be concerned about snakes because there were no poisonous snake even in the wildest of areas. Rattlesnakes were once common there, but bounties put on their rattles destroyed them all by the early 1900’s.

Here in Florida, it is a different story. Rattlesnakes, pygmy rattlesnakes, coral snakes, cottonmouths and copperheads are all venomous snakes that you need to be aware of.  So, I was excited to learn that a snake was  ahead, not so much my wife. It was a young southern pine  snake, about 20 inches in length.  Pine snakes grow to a sizeable length of four to six feet  or more from eating other snakes, mice, rats, birds, squirrels, rabbits,  lizards, and other tasty treats. These snakes can live upwards of 20 years under good conditions.

The snake was so still on the concrete that I thought it might not be alive. After shooting a few photographs of it, I asked Anne to find a long stick so I could poke it to see if it was dead or not. I poked it once and it didn’t move. I poked it a few more times and it then coiled with its head raised in the air. It watched my every move as I walked around it to photograph it. For its safety and the safety of the residents who walk their dogs here, I continued to poke it with the stick to get it to move back into the woodlands. Although I was able to get it to move, it was feisty for its small stature and often coiled  and struck the stick. Eventually I was able to coax it off the sidewalk and watched it slither away to the safety of the woodlands.

The Life Around Water Lilies

Water lilies are in ponds around the world. There are many different species, but they all perform the same functions. Fish will often hide under the canopy of the lily when sensing osprey and other raptors seeking fish to eat. Turtles and frogs find shelter and food among the lily pads. Alligators float in the midst of the lily pads to blend in with the environment so they can pounce on ducks and other birds that swim around the pads. Bees and other insects come to the  lily flower to sip its nectar. For me, I just enjoy the beauty of the plant and the opportunities it provides to see many of God’s creatures.

The Monarch Mimic? Or is it the Other Way Around?

At one time this butterfly was thought to mimic the poisonous monarch butterfly to protect itself from being eaten. Monarch caterpillars eating milkweed absorbed  substances called glycosides that are not only distasteful, but harmful to the heart of predators eating them. The non-poisonous viceroy butterfly gained protection from predators by mimicking the monarch.

But in the 1990’s scientists conducted an experiment that proved that viceroy butterflies are not very palatable either. Viceroy butterflies are distasteful because these caterpillars eat – willows and poplars, two tree families that produce noxious chemicals to deter herbivores from eating these leaves. Viceroy caterpillars absorb salicylic acid from these trees that ultimately makes the viceroy butterfly bitter tasting.

These two butterfly species have co-evolved to mimic each other for protection from birds and other marauders.  Their brightly orange colored wings warn predators to steer clear of them. Yet 15% of the wintering monarchs in Mexico are predated each year by two birds -the black-backed oriole and the black-headed grosbeak as well as the black-eared mouse. How these birds and mouse are able to eat monarchs without consequences is poorly understood.

Although this mimicry protects monarchs and viceroys from most vertebrate species (those with backbones), it does not thwart predation from wasps, spiders, bacteria and viruses. Such is the balance of nature!
