Posts Tagged ‘Storeria dekayi’

I was a bit startled on Tuesday when I spotted this small, pale snake as I was walking along a trail at Occoquan Regional Park. In the first place, I am not used to seeing a snake at waist level, coiled up atop the vegetation. Secondly, I have never seen a snake that looked like this one. Was it a young snake of a familiar species?

I did some research and determined that it is almost certainly a DeKay’s Brown Snake (Storeria dekayi), a snake that on average is only 9 to 13 inches (23 to 33 cm) in length in Virginia. I had never even heard of this snake, so I headed over to the Virginia Herpetological Society for some information. According to the society’s website, “Dekay’s Brownsnakes are terrestrial, secretive, and seldom found in the open. They are nocturnal, but are most often found under surface objects such as boards, trash of all sorts, logs, and rocks. Their microhabitat may be described as the soil-humus layer.” I am not sure why this one was in the open, but the fact that this species spends a lot of time in the dirt, where it feeds primarily on slugs and worms, explains why I have never seen one before.

I was intrigued to note that this species is viviparous, which means that it gives birth to living young rather than lay eggs as many snakes do. The gestational period is 105 to 113 days and the average litter size is about 11, according to the Virginia Herpetological Society website, which also noted that “mating has not been observed in Virginia.” After the young are born there is no parental care involved, but sometimes young brown snakes will stay close with the parent, according to information on the Animal Diversity Web website.

I have visited this park dozens of times at different times of the year and it is exciting for me to be able to continue to spot new species there. It is humbling to think about how little I know about the diverse population of living creatures in this one location.
