As a kid I would have spent all my time catching frogs, snakes, & turtles and would have mostly ignored the spiders, moths & butterflies. The species list is from Massachusetts Wildlife, No. 2, 2009 Field Guide to the Reptiles of Massachusetts. Italicized entries are not found in Middlesex County.

Chelydridae (Snapping Turtles)

Chelydra serpentina (Snapping Turtle) (Parker Meadow, 7/1/12 1pm, 8/2/2014 4pm) I have seen several crossing roads, some successfully, others not, but I've never had a camera handy at the time. My whole baseball team got an excellent look at one as it strolled all the way across the outfield during a game at the Harrington field. Again, no camera.

Colubridae (Colubrid snakes)

Coluber constrictor (Black Racer, North American Racer) (Upper Vine Brook path, 4/03) I actually didn't see it, but my wife did and called me on my cell phone. I ran to the bike path, but before I could get there a little girl ran over the snake with her bicycle. The wounded snake disappeared into the woods.

Carphophis amoenus (Eastern Wormsnake, threatened)

Diadophis punctatus (Ring-necked Snake)

Pantherophis alleghaniensis (Eastern Ratsnake, endangered)

Heterodon platirhinos (Eastern Hog-nosed Snake, protected)

Nerodia sipedon (Northern Watersnake)

Opheodrys vernalis (Smooth Greensnake)

Thamnophis sirtalisjuvenile mating Thamnophis sirtalis (Common garter snake) (Whipple Hill, 9/23/07 12pm, Lower Vine Brook, 10/8/11 3pm, mating 4/12/14 11am) The second photo is of a juvenile, only about 6-8" long. It was sunning itself on the bike path and was quite ferocious about defending its spot. It struck at my hand multiple times, but I couldn't get a photo with its mouth open. My wife and son saw one trying to eat a tufted titmouse in our back yard. It wasn't clear if it killed the titmouse itself or if it found it dead. It gave up after it could only fit the head into its mouth.

Thamnophis sauritus (Eastern Ribbonsnake)

Storeria dekayi (Dekay's Brownsnake)

Storeria occipitomaculata (Red-bellied Snake)

Viperidae (Vipers)
