Typically, when people think about the garter snakes, the first member of the genus they think of is the eastern garter snake, Thamnophis sirtalis sirtalis.
This member of the Thamnophis genus is quite common and has a broad range here in North America with many color phases. They can be found in just about any habitat that has a water source where there typical prey of frogs, toads, and other amphibians can be found, and are often found in backyards, gardens, city parks, and other suburban areas.
However, there is another subspecies of garter snake, the blue striped garter snake (Thamnophis sirtalis similis) that is far less common, has a much smaller range and in my opinion is a very beautiful snake. The blue striped garter snake, as its name implies, is a dark colored snake, almost black, with a distinct blue stripe on both sides of its body and sometimes a faint blue dorsal stripe.
This subspecies lives in coastal regions of the eastern Florida panhandle and down trough the Big Bend down the Gulf Coast. It is often found in marshes and even in salt marsh habitat where its principle prey is also small amphibians like frogs, toads, tree frogs, and even aquatic salamanders.
We recently discovered a large female blue striped garter snake while hiking a trail in North Florida. They are are a very beautiful species to see in person. This one was basically black with neon blue stripes. She had been basking in the open when we spotted her so she was fast and alert and was not easy to collect for photographs, but after a few minutes of chasing her through vine tangles, briars, a saw palmetto, and even a couple of cactus, we were able to secure her for a few photographs.
She showed her displeasure by repeatedly biting my herping partner and smearing him with an extremely pungent musk. It was all worth it, of course, to be able to get pictures of such an incredibly beautiful and not so common garter snake! …read more
