As a kid I would have spent all my time catching frogs, snakes, & turtles and would have mostly ignored the spiders, moths & butterflies. Italicized entries are not found in Middlesex County.

Ranidae (True Frogs)

Leopard frogRana pipiens (Northern leopard frog) (Willard's Woods, 8/18/02 11am, Whipple Hill, 8/1/08 11am) There is a moderate chance these are really a Pickerel frogs.

Rana palustrisRana palustris (Pickerel frog) (Willards Woods, 7/21/01 11am) I am moderately confident I've gotten this identification correct. The yellow on the undersides of the hind legs is diagnostic for the Pickerel frog, as compared to the Northern leopard frog.

Rana sylvatica (Wood frog) (Lower Vine Brook, 7/1/15 1pm, 9/14/13 2pm, Willards Woods, 9/7/02 2pm, 3/18/12 1pm)

eggs (Whipple Hill, 4/9/11 2pm)

Rana catesbeiana (Bullfrog) (Whipple Hill, 8/26/01 3pm) Rana catesbeianaI don't know if it is due to global warming, but this bullfrog was out and about on January 6! (Upper Vine Brook, 1/6/07 3pm) (Parker Meadow, 8/20/12 11am) A blue frog! The blue color is due to a lack of yellow pigment.

Rana clamitansRana clamitans (Green frog) (Whipple Hill, 9/21/08 2pm)

Hylidae (True Tree Frogs)

Hyla cruciferHyla cruciferadults Hyla cruciferHyla crucifera baby Hyla crucifer (Spring peeper) (adults Whipple Hill, 8/31/10 2pm, baby Willards Woods, 7/16/06 7pm)

Hyla versicolor baby (Gray Treefrog) (Lexington High School, 7/22/17 3pm)

Bufonidae (True Toads)

Bufo americanusBufo americanus (American toad) (Lower Vine Brook, 8/30/08 1pm (2), Lexington 5/28/06 9am (2), Willard's Woods 5/26/12 12pm (2), 6/1/13 10am) Bufo americanus tadpoletadpole (just growing legs, one of many -- see next photo) Bufo americanus tadpolestadpoles (Lower Vine Brook, 6/25/08 11am) eggs (Lower Vine Brook, 4/20/12 2pm)

Bufo woodhousei fowleri? (Fowler's Toad) (Willard's Woods, 6/24/12 12pm) I think this is a Fowler's toad, although many of the American toads (maybe) I've found look awfully similar. This toad has the dorsal stripe and a spotless chest and belly (not photographed, but I flipped it over to check). However, it is hard to tell if it has 3 or more warts per blotch. I know the two species hybridize, so perhaps many of the toads I've seen are hybrids.

Scaphiopus holbrookii (Eastern Spadefoot Toad)

Plethodontidae (Lungless Salamanders)

Red-backed salamanderPlethodon cinereus (Red-backed salamander) (Whipple Hill, 5/20/00 3pm, Willard's Woods, 9/28/02 12pm, Lower Vine Brook, 5/4/13 11am)

Ambystomatidae (Mole Salamanders)

Blue-spotted salamanderAmbystoma laterale (Blue-spotted salamander) (Beverly, 11/03/03 6pm) I was shocked to see this little one sitting in the middle of the cement path connecting my office building to the parking lot! I brought it inside for its picture.

Ambystoma maculatumAmbystoma maculatum (Spotted salamander) (Lower Vine Brook, 9/14/13 2pm, Whipple Hill, 9/9/07 12pm)

(Whipple Hill, 8/21/12 1pm) A young spotted salamander? I didn't have my net with me and it scooted away when I tried to grab it.

Ambysoma jeffersonianum (Jefferson Salamander, special concern)

Aquatic adult Notophthalmus viridescenseft aquatic larva Notophthalmus viridescens (Red-spotted newt) (Lower Vine Brook, 5/28/11 2pm, 10/6/12 4pm, Whipple Hill, 9/1/07 11am, 8/21/12 1pm for red eft & larva, Lower Vine Brook, 7/14/13 12pm)
