I am not an avid butterfly enthusiast, but I enjoy a nice butterfly as well as the next guy.
female male 4th? instar larva Papilio glaucus (Eastern Tiger Swallowtail) (Lexington, 7/30/06 10am, Lower Vine Brook, 8/28/09 2pm, 7/23/11 3pm, Willard's Woods, 8/9/03 5pm, Whipple Hill, 8/20/16 12pm)
adult from the pictured caterpillar adult pupa caterpillar, 4th instar caterpillar, 5th instar caterpillar, 5th instar about to pupate, probably 5th instar, Papilio troilus (Spicebush Swallowtail) (Lower Vine Brook, 7/30/11 11am [2 photos], Lexington, 7/28/02 2pm, Lower Vine Brook, 7/16/11 12pm, 7/4/11 9pm, 7/13/11 7pm, Whipple Hill, 6/23/12 12pm) My son & I raised the more yellow-green caterpillar from a 4th instar larva (which wouldn't extend its "tongue" for a picture), to a butterfly. The brighter green caterpillar I found in the woods.
female male late instar caterpillar Papilio polyxenes (Eastern Black Swallowtail) (Willard's Woods, 8/11/02 3pm, 7/13/13 3pm, Arlington, 9/6/18)
Battus philenor (Pipevine Swallowtail)
Papilio cresphontes (Giant Swallowtail) Historical, no recent MA sightings.
Eurytides marcellus (Zebra Swallowtail) Historical, no recent MA sightings.
Colias philodice (Common Sulphur, Clouded Sulphur) (Willard's Woods, Lower Vine Brook, 9/21/09 2pm) I am not 100% sure about any of the 3 Colias pictures. They all could be either philodice or eurytheme.
Colias eurytheme? white form (Orange Sulphur) (Lower Vine Brook, 8/23/09 1pm)
Colias interior (Pink-edged Sulphur)
male female female caterpillarfemale pupa Pieris rapae (Cabbage White) (Willard's Woods, 7/5/05 11am, Lexington 6/17/09, Lexington 5/30/09 10am, Lexington 6/3/09 10am) The female will sit on a flower upside-down, wings spread, and arch her abdomen to entice a male to mate! This caterpillar was happily munching invasive garlic mustard. I brought it home and it has now pupated (6/3/09, or perhaps 6/2/09). A female emerged either yesterday or early this morning, 6/17/09 after 14-15 days.

Callophrys niphon (Eastern Pine Elfin) (Willard's Woods, 5/13/07 10am, Lower Vine Brook, 5/11/14 2pm) There were several feeding on blueberry flowers near a stand of pine trees in Willard's Woods.
adult larva Everes comyntas (Eastern tailed blue) (Willard's Woods, early spring, 7/5/02 3pm, Lower Vine Brook, 9/25/16 4pm) The caterpillars were on bush clover.
Celastrina sp. (Spring Azure) (Arlington Great Meadows, 4/25/10 11am, Willard's Woods, Lower Vine Brook, 6/25/08 2pm) This is a most frusterating species (really a group of hard to differentiate species). They are a beautiful blue on the top of the wings. However, they only sit with their wings folded up, hiding the coloration.
Libytheana carinenta (American Snout)
Euptoieta claudia (Variegated Fritillary)
Speyeria cybele (Great Spangled Fritillary) (Willard's Woods, 9/4/04 2pm, Lower Vine Brook, 7/1/08 1pm, 7/11/10 4pm, Lexington, 5/30/03 11pm)

Polygonia interrogationis (Question Mark)
adults larva pupa Polygonia comma (Comma) (Willard's Woods 7/7/04 4pm, 6/24/07 11am, Dunback Meadow 7/18/09 3pm, Lower Vine Brook, 6/10/12 10am, Willard's Woods, 6/10/12 11am, 9/29/13 1pm, Lexington, 6/15/12, 6/20/12 10pm) A large number all appeared at roughly the same time in Willard's Woods, then disappeared within a week or so. There were several in Dunback Meadow, including the one above which was drinking my sweat. I saw my first one of the new year (2010) today, 3/20, the first day of spring. I didn't get a good look, so it could have been a Question Mark and not a Comma. The second-to-last photo of an adult was taken when it landed on my leg.
Polygonia progne (Gray Comma)
Nymphalis vau-album (Compton Tortoiseshell)
Nymphalis antiopa (Mourning Cloak) (Lower Vine Brook, 3/28/09 1pm, 3/19/10 11am, Lexington 3/27/04 1pm) The second & third pictures are of the same butterfly. It was lapping up water from the ground and was happy to let me pick it up so it could lap up the salt from my sweat. Its tongue felt very interesting on my finger.
Nymphalis milberti (Milbert's Tortoiseshell)
ovipositing Vanessa virginiensis (American Lady) (Lower Vine Brook, 9/8/12 12pm, 4/20/12 2pm, Willard's Woods, 9/1/2019 4pm)
Vanessa cardui (Painted Lady) (Parker Meadow, 8/20/12 11am, Lower Vine Brook, 8/19/17 12pm) I have seen dozens over the last several days in 2012. I counted 5 at once in my small backyard garden.
adult larvae Vanessa atalanta (Red Admiral) (Dunback Meadow, 7/18/09 3pm for 1st picture, Lower Vine Brook, 5/27/12 11am, 7/6/08 12pm, 6/17/12 11am, 6/19/2019 8am) Earliest sighting 5/9/10. Larvae on stinging nettle. 2012 was a fantastic year for Red Admirals, as well as several other migratory butterflies. I saw perhaps 2 or 3 dozen in a single hour or so last week.
Junonia coenia (Common Buckeye) (Lower Vine Brook, 9/7/2019 3pm)
adult larva Limenitis arthemis astyanax (Red-spotted purple) (Lexington, 6/2/02 1pm, 6/4/04 11pm freshly emerged from chrysalis, Willard's Woods, 6/17/12 12pm, caterpillars 6/29/15 11am) The Red-spotted Purple and the White Admiral are the same species, just different color variants.
White Admiral (Limenitis arthemis arthemis) (Whipple Hill, 8/20/16 12pm) I am embarassed by the quality of this photo, but the butterfly surprised me while I was watching a great blue heron and it disappeared into a tree quite a ways away. This was the first White Admiral I've ever seen.
adult Limenitis archippus (Viceroy) larva (Willard's Woods, 7/19/2020 12pm (2), 9/30/06, Lower Vine Brook, 7/21/2019 10am, caterpillar, Willard's Woods, 7/6/03 2pm)

Coenonympha tullia (Common Ringlet) (Willard's Woods, 8/4/02 11am, Lower Vine Brook, 8/6/11 5pm) It looks like C. tullia could be a complex of hard to distinguish species, including C. inornata (Praire Ringlet).
Cercyonis pegala (Wood Nymph) (Willard's Woods)
adult female ovipositing mating late instar larva late instar larva preyed upon by assassin bug pupa egg Danaus plexippus (Monarch) (Lexington, 7/23/06 11am, 7/30/06 1pm, 8/2/06 9am, 8/2/06 9am, 8/9/06 10pm, & 8/20/06 10am, 7/14/07 1pm, 7/14/07 1pm, mating Lower Vine Brook, 7/4/08 4pm) 2006 was a very good year for monarch butterflies. I've seen more this year than the last 5 combined. It is also the first year that I've seen caterpillars in my yard. Unfortunately, none have made it to pupate. I haven't seen any birds eating them, but assassin bugs seem to greatly enjoy them. A breakthrough! Once intrepid caterpillar managed to avoid an untimely doom and made a nice chrysalis. Unfortunately, it didn't succeed in its metamorphosis and the pupa died.

Erynnis juvenalis (Juvenal's Duskywing)
male Erynnis horatius (Horace's Duskywing)? (Willard's Woods, Lower Vine Brook, 5/28/11 1pm) The second butterfly was very large for a skipper. It was flying with a smaller, darker butterfly that I could not get a picture of, although it looked much the third photo which was taken in a different area.
male male Erynnis baptisiae (Wild Indigo Duskywing)? (Whipple Hill, 4/21/10 3pm, Willard's Woods, 7/20/02 1pm) I am not at sure that I've got any of the 3 Erynnis photos correctly identified. The April 21st date would be the earliest recorded (at least by MassAudubon) for either of my 2 guesses for species, and none of the other likely candidates fly any earlier. Any help identifying these would be appreciated.

Polites themistocles (Tawny-Edged Skipper) (Lower Vine Brook, 7/12/08 11am, 8/9/08 4pm) I'm not too sure about the first identification...
