Thamnophis sirtalis sirtalis
An Eastern Gartersnake spotted at Huntley Meadows Park. Did you notice the fly (Family Muscidae) perching on the snake’s head, as shown in Photo 1 (of 3)? When I saw the fly through the camera viewfinder my first thought was, “Either pre-molting snakes are vision-impaired/blind or this fly has a death wish!” Turns out I was partly correct. "Blue-to-gray eyes are usually a sign that the snake is about a day away from molting/shedding its skin. When the eyes are blue-gray their vision is impaired — they can still see some movement and light versus dark, but not much detail."
