New backyard herp: Ringneck snake (Diadophis punctatus)

Fear of snakes is instinctive. It just is. I imagine that most of those who have overcome it have done so through repeated exposure, knowledge gained over time. It’s not enough to know that an animal is harmless; you have to feel it. And if you don’t, you’ll still be scared by something as innocuous as a 5-inch long ringneck snake (Diadophis punctatus) that you might find swimming in your backyard pool.

I found that out one night this summer when Daniel was in the pool and I spotted one a few yards away from him. I didn’t want Daniel to scare it (or be scared by it), so I casually slipped back inside the house and ran to get the camera. The snake was a tiny little fellow and quite content to hang out in the corner of the pool. Unfortunately, that corner was a bit close to where the lad was playing on the steps of the shallow end. And despite my attempts to keep the snake out of Danny’s sight, that proved impossible. (Gee, for some reason my two-year-old son took an interest in whatever it was I was pointing my camera at in the pool. Go figure!).

When he noticed the snake, Daniel got very excited—scared, even—and left the pool; wouldn’t get back in until I’d removed the little dude.

Ringnecks are one of the most abundant snakes in North America, both in terms of range and population. They are found across most of the country, and some studies have estimated their abundance in the hundreds to thousands of individuals per hectare. They’re small terrestrial burrowers that feed on just about anything (earthworms, salamanders, small frogs, small snakes and lizards, and insect larvae, according to Gibbons and Dorcas); the fact that they’re small means that just about anything can feed on them as well.

Ringneck snakes are, according to the Florida Natural History Museum,

the most frequently found snake in Florida swimming pools—they crawl in to get a drink and then cannot climb out because they are too small to reach the lip of the pool.

I’m sure the herpetologists at the FLMNH have no problem handling snakes, even venomous ones. They’re trained to do so, and any fear they might once have felt has vanished with the confidence in their own abilities to handle these critters. However, their advice for the average homeowner understandably takes the layperson’s squeamishness into account:

If you find one in your pool, lift it out with the leaf skimmer or a dipnet and turn it loose in the shrubs where it can get back to eating things you do not want in your garden.

And I can vouch for the efficacy of their advice. After my two failed attempts to grab this little guy by hand (and he was barely longer than my hand’s width), he retreated to the middle of the pool, where I had to resort to the skimmer to scoop him out and get him to safety. Why did my first two attempts fail? Because the little guy wriggled out of my grasp, and I am no snake wrangler, no herpetologist with long experience in how to corral these critters. I’m just an amateur naturalist, interested in, but sometimes a bit scared of, nature. (I don’t have the ophidiophobia of an Indiana Jones, but they do creep me out, just a bit.)

Greene writes

Humans have always regarded snakes with a mixture of inquisitiveness and fear, of awe and revulsion, but whether these conflicting tendencies reflect genetically based predispositions or cultural traditions has long been controversial. In laboratory experiments and field observations, primate responses to snakes range from instant terror through curiosity and mobbing to immediate consumption; that some naive nonhuman primates react negatively to snakes suggests an inborn response with obvious survival value.

Now, mind you, just because a snake is small doesn’t mean it’s harmless. Pygmy rattlesnakes aren’t a whole lot bigger than ring-necked snakes, but their venom is quite potent. You won’t ever confuse them, because they look nothing alike, but it’s always best to treat an unknown snake with caution.

Cheers!
