Eastern Gartersnake

An Eastern Gartersnake (Thamnophis sirtalis sirtalis) was spotted during a photowalk along Easy Road at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA.

After taking a closer shot of the snake’s head (above), I backed away for a wider view that shows the snake is a little more than two (2) feet in length (below).

Eastern Gartersnakes can be differentiated from Common Ribbonsnakes (Thamnophis sauritus sauritus) by the presence of “dark vertical lines on the supralabial scales.” This key characteristic is shown clearly in the following photo.
