A Promethea Silkmoth (Callosamia promethea) landed on Rutland photographer Anne Greene's leg while she was in her yard in June. These beautiful moths have no mouth parts and do not feed in this adult stage. Their sole occupation is mating and egg-laying.

The gypsy moth (Lymantria dispar dispar) infestation of the past couple of years continued throughout much of southern Worcester County. This female Eastern Towhee (Pipilo erythrophthalmus) was carrying a gypsy moth caterpillar to feed nestlings in June at Muddy Brook WMA, Hardwick, where they are common nesters. Photo by Alan Rawle

Ted Purcell was fortunate to encounter some Cedar Waxwings (Bombycilla cedrorum) in Rutland in early January. They have been uncommon in our region since their breeding season ended in August.

Winterberry or Black Alder (Ilex verticillata) produced abundant fruit in 2017. An important role played by winterberry is as a fall and winter food source for songbirds: the fleshy, bright red berries are said to be toxic to humans, but fruit-eating birds such as robins, mockingbirds, Eastern Bluebirds, and Cedar Waxwings evidently find them palatable. It is possible that, as with American Holly, the levels of toxic or unpalatable chemicals in winterberry berries decline as the fruit matures and hangs on the shrubs. In our area at least, winterberry seems to be eaten by the birds after the winter solstice.

In Rutland, this immature Yellow-bellied Sapsucker (Sphyrapicus varius) visited Doug Wipf's birdfeeding station from fall through 29 December 2017. Whether the bird moved on prior to the oncoming storm (birds react to barometric pressure changes and can adjust their behaviors) or simply didn't survive is unknown.

This 2 1/2 inch salamander responded to the heavy rains and high temperatures of 11-12 January by emerging from its winter shelter beneath the rocks. When the temperatures dropped into single digits on the 13th, it presumably resumed hibernation, withstanding the freeze by a chemical change in the body that bathes its organs in a glucose-filled fluid "antifreeze."

A sweat bee (Agapostemon virescens) * Only mated females survive the winter.

The hairs on the body of this fly point to a tachinid species, Euclytia flava. Tachinids are internal parisitoids of other insects, the females often laying eggs directly on the host insect.

A sweat bee of the Augochlorini tribe. These metallic green pollinators, difficult to identify in the field, also feed on the honeydew secreted by aphids in warmer months.

Two-spotted Bumblebee (Bombus bimaculatus) and potter (or mason) wasp (Parancistrocerus perennis).

Red Admiral (Vanessa atalanta) Male red admirals are territorial. Territories tend to be oval in shape, 8-24 feet long, and 13-42 feet wide. In order to maintain their territory, males must fly around and patrol an area dozens of times per hour. Only males of exceptional flying ability are able to prevent intruding males and successfully court females. (Wilkipedia)

Variegated Fritillary (Euptoieta claudia) This species is closely related to other fritillaries, but there are important differences in their life history. They have two or three broods per year vs. one per year (as Great Spangled Fritillary) ; they are nomadic vs. sedentary--the ones we see here are flying in from other states ; and they use a wide range of host plants vs. just violets.

Eastern Tailed-blue (Cupido comyntas) Caterpillars of this species eat the flower buds, flowers, seeds and new leaves of their host plants in the L-legume family like yellow sweet clover, alfalfa, vetch, white clover, wild pea, bush clover, and tick-trefoil. Eastern Tailed-blues overwinter as caterpillars (often in the seed pod of their legume host) and pupate the following spring.

Common Buckeye (Junonia coenia) This was a good flight year for this seasonal immigrant species. It is a regular summer and fall immigrant into Massachusetts, but it cannot survive winters here so far as is known. It re-populates southern New England each year from larger populations further south, and is able to produce one or more generations here, depending on the date of arrival.

Red-spotted Purple (Limenitis arthemis astyanax) Two distinct phenotypes of Limenitis arthemis, the southern-based Red-spotted Purple (non-banded) and the northern-based White Admiral (white banded), occur in Massachusetts. The two forms were long treated as separate species, and they are sufficiently differentiated that most authors today refer to them as subspecies. The state is in the blend zone between these two venerable forms, so that many intergrades (“hybrids”) are also found here. (Butterflies of Massachusetts web-site)

Monarch (Danaus plexippus) Sightings of this popular species were more frequent this summer than in the past two years, but the species is still in decline. A study published in Science News this spring made a strong case that the reasons for this decline go far beyond what's happening on the wintering grounds. The study provides the first empirical evidence of a negative association between glyphosate (the main ingredient in the herbicide Roundup) application and local abundance of adult monarch butterflies during 1994-2003, the initial phase of large-scale herbicide adoption in the Midwest. Reduction of milkweed plants available as host plants may be one big reason for the shrinking Monarch population.

Fiery Skipper (Hylephila phyleus) Like our other migratory skippers, Fiery Skipper typically arrives in Massachusetts toward the middle or end of the summer season. It may become a temporary colonist, perhaps raising a brood, but it does not persist here owing to lack of cold tolerance. It cannot survive the winter.

Eastern Tiger Swallowtail (Papilio glaucus) This large and showy species is one of the most familiar butterflies in Massachusetts. The first known drawing of a North America butterfly was of an eastern tiger swallowtail. It was drawn by John White in 1587 during Sir Walter Raleigh's third expedition to Virginia. (Wikipedia)

Banded Hairstreak (Satyrium calanus) In Massachusetts, the main plants that host the caterpillars of this butterfly appear to be oaks, especially red (Quercus rubra) and scrub (Q. ilicifolia) oaks.

Painted Lady (Vanessa cardui) This migratory species occurred in high numbers in Massachusetts this year. While warm season migrations are often easily observed, e.g. hundreds sometimes seen flying onshore during a migratory movement, autumn migrations take place at high altitude, which explains why these migrations are seldom witnessed.

Great Spangled Fritillary (Speyeria cybele) Various species of native violets have reported to serve as a larval host plant for the great spangled fritillary, including the native round-leaf violet (Viola rotundifolia), the arrow-leaf violet (Viola fimbriatula) and the common blue violet (Viola sororia).

Northern Pearly-Eye ( Lethe [Enodia] anthedon) This butterfly is the region’s most forest-adapted butterfly. Its larval hosts are woodland grasses; adults feed on sap from tree wounds. Northern Pearly-Eye is usually found in the shady under-story, rather than the sunny canopy, and is often perched head-downward on tree trunks. (Butterflies of Massachusetts website)

Gray Tree Frog (Hyla versicolor) in Hardwick on 6/22. Adults rarely descend from high treetops except during the breeding season. According to Wikipedia, mating calls and chorusing are most frequent at night, but individuals often call during daytime in response to thunder or other loud noises.

Northern Paper Wasps (Polistes fuscatus), which build their nests in June, are interesting creatures that conjure up misplaced fears. This placid queen, which will die by fall, has built a nest from wood fibers and laid eggs that will develop into new queens. Color patterns of P. fuscatus are highly variable and strongly influenced by geography. Wasps can even recognize each other's individual faces due to the great amount of variability.

On 6/8, Linda Leehy spotted this Giant Swallowtail (Papilio cresphontes), a species more common in southerly locations, in her Gilbertville yard. The early date suggests that the butterfly, rare- to-uncommon in central MA, probably successfully overwintered as a chrysalis. The Butterflies of Massachusetts web-site states: "Giant Swallowtail faces difficult conditions in over-wintering in Massachusetts, but some have been surviving in warmer winters in suitable locations. Climate warming will probably lead to an increase in Massachusetts of this southern-based species both through over-wintering and increased immigration each spring. "

A Hobomok Skipper (Poanes hobomok) and a potter wasp (Ancistrocerus adiabatus) search for nectar on Purple Vetch (Vicia cracca), a non-native plant brought to North America as a forage plant and for its ability to fix large quantities of nitrogen. It is a favorite of nectaring insect species. Unless it is aggressively crowding out native species, a small amount of this vetch can be tolerated in the landscape.

Painted Turtle (Chrysemys picta) laying eggs on 6/8 in Hardwick. The sex of the young is determined by the temperature of the nest; cooler temperatures favor males, warmer temperatures favor females. This nest was protected from predators with wire, so in August or early September, we hope to see young emerge. Temperatures were up and down this summer, so who knows which sex will prevail. After emerging, the young will instinctively seek out the security of the nearby pond.

CAN YOU GUESS THE SPECIES OF THIS BIRD? Jim Morelly sent us this puzzling image of a bird seen in the distance. He was able to grab this shot and described the bird as being about the size of a Scarlet Tanager. For the answer, go to our HOME page.

Our FROM THE FIELD post wouldn't be complete without one of Jim Morelly's stunning mammal photographs, this one of a White-tailed Deer in the Quabbin region.

A photographer who was focused on another subject inadvertently captured this image of a Black-billed Cuckoo (Coccyzus erythropthalmus) feeding a fledgling. Cuckoos of both species were abundant this year, albeit extremely camera-shy. They feasted on Gypsy Moth (Lymantria dispar dispar) caterpillars, one of their preferred foods. Indigestible hairs of the caterpillars hairs accumulate in the stomach until the bird sheds the stomach lining and disgorges a pellet.

Variegated Fritillary (Euptoieta claudia) in Hardwick on 6/29. According to butterfliesofmassachusetts.net, this species is a regular temporary colonist, arriving in Massachusetts from its year-round range further south. It seems to be appearing earlier in the last 25 years than it did historically. Photo by Bette Robo.

Around the beginning of May, just as we were planning to discontinue feeding the birds and avoid attracting bears, Rose-breasted Grosbeaks (Pheucticus ludovicianus) began showing up for sunflower seeds. Photo by Bob Stetson.

The long, continuous series of warbles, chirps, chips, and mews--sometimes for as long as ten minutes-- emanating from a thick tangle of shrubbery or vines--means that a Gray Catbird (Dumetella carolinensis) has arrived from its wintering grounds and is planning to spend the next five months somewhere nearby.

Right on schedule, this Solitary Sandpiper (Tringa solitaria) was found in Warren on May 6th, en route to breeding territory in Canada. Unlike other sandpipers, Solitary Sandpiper lays its eggs in the tree nests of several different song birds, particularly those of the American Robin, Rusty Blackbird, Eastern Kingbird, Gray Jay, and Cedar Waxwing. See allaboutbirds.org for more information. Photo by Jim Engberg.

Juvenal's Duskywing (Erynnis juvenalis) was common at Muddy Brook WMA in Hardwick in May.

Three-banded Lady Beetle (Coccinella trifaciata), one of twelve species of lady beetles in North America, was spotted in Hubbardston.

A little bird with a voice that seems more fitting for a bird with a larger body, Tufted Titmouse (Baeolophus bicolor) is known to most feeder watchers. While chickadees and other small forest birds gather in winter foraging flocks, Tufted Titmouse remain on or near their breeding territory year-round. Mated pairs may be accompanied by the offspring they raised the previous year. Photo taken in Hubbardston by Bob Stetson.

That new trilling song you start to hear right about the time the Fox Sparrows depart in mid-April is coming from a Chipping Sparrow (Spizella passerina). They are common across North America and will nest close to areas of human habitation as well as in undeveloped tracts of land.

When Fox Sparrows (Passerella iliaca) show up under your bird feeder, you know that spring is on the way. These birds have to get started on their northward migration early because their breeding grounds are in the high Arctic region. They show up in central Massachusetts in mid- to late-March and often can be heard singing before they depart. These Hardwick sparrows departed with the warm front from the south on 9 April.

If you watch White-breasted Nuthatches (Sitta carolinensis) a lot, you know that this is the pose you usually see. Male White-breasted Nuthatches sing in late winter and spring, a rapid, nasal, fairly low-pitched wha-wha-wha that lasts 2-3 seconds. It’s made up of a half-dozen to a dozen nearly identical notes. Males sing these songs at two rates, with the faster version packing in twice as many notes in the same amount of time. The fast version is thought to be the main one used for mate attraction. (Song info from allaboutbirds.org) Photo by Bob Stetson.

Ospreys (Pandion haliaetus) rarely nest along inland waterways in central Massachusetts, but they are reliably seen at ponds, lakes, and rivers here in April while en route to the coast. This bird was at Harvard Pond in Petersham on 9 April.

Some Song Sparrows (Melospiza melodia) chose to spend the winter here while others withdrew to more southerly states and are now returning. However, they didn't begin singing until increasing daylight at the end of March triggered hormones that signal the start of the breeding season.

A few Eastern Phoebes (Sayornis phoebe) showed up just before the April 1st snow- and ice-storm and probably had to subsist on small seeds and fruits until insects began hatching. There was a large influx a couple of days after the storm, and they're already prospecting for nest sites. They may drop out of sight during stretches of bad weather before returning to begin nest-building in earnest.

Listen for the distinctive irregular drumming of the Yellow-bellied Sapsucker (Sphyrapicus varius) in wooded areas. These birds drill two types of holes in trees to harvest sap. The sap wells they create also attract hummingbirds, butterflies, bats, and even porcupines, and benefit these creatures by providing a good energy source. This bird was found in Petersham on 9 April. Photo by Alan Rawle.

As the Cornell Lab of Ornithology website allaboutbirds.org says, a Killdeer (Charadrius vociferus) is a shorebird you can see without going to the beach. In March and April some are returning from wintering grounds in Central America while others spent the winter in places like Florida or the coasts of the Carolinas. Watch for them in large, cultivated expanses of grass or crop fields.

No, not a central Massachusetts sighting, but this Great Gray Owl (Strix nebulosa), an Arctic breeder rarely seen in winter in New England, was present a couple of hours away in Newport, Vermont from 25 February to about 2 April. WRNC member Jim Morelly shared his photograph of this charismatic bird.
