Photo of the Month

This giant salamander is the only one of its kind in North America—its closest relatives are found in Japan and China. It is highly specialized for its habitat, living only where there is well oxygenated, fast-moving water. Reaching a length of 30 to 74 cm (12 to 29 in), it is the third largest amphibian in the world behind its Asian cousins. This summer, we’ll be adding a model of this animal to our Pocono exhibit…do you know what name will appear on the label? Photo credit: Brian Gratwicke

April Lyrids

Lyrid Meteor Shower

The month of April welcomes one of the oldest known meteor showers in history, with sightings going back almost 2,700 years. Comet Thatcher, which has a 415-year orbit, won’t return to our solar system until the year 2276. But the remnants the comet leaves behind during each visit cause fireworks in the sky when the Earth passes through a patch of its tail each year. The meteors seem to be coming from the constellation Lyra, leading to their name—the April Lyrids. Photo: NASA/JPL


Harbinger of Spring

Erigenia bulbosa: Harbinger of Spring

This perky little flower is nicknamed “harbinger of spring” because it is one of the earliest blooming flowers in our region, even punching through the snow in February. But if you see one, don’t pick it! Even though it is a member of the common carrot family, it is on the threatened species list in Pennsylvania and the endangered species list in New York. Another nickname is Pepper & Salt, referring to the contrast between the white petals and black anthers. Photo: Chris Packard



Black-capped (Poecile atricapillus, left) and Carolina (Poecile carolinensis, right) Chickadees

These little guys frequent bird feeders in the winter, but their identification can be confusing. They usually remain separated into two distinct geographic regions, only overlapping where their ranges meet. In recent decades, however, that range of overlap has gradually moved north, and it now includes the Pocono Mountains. You might see both species at the same feeder, and even some hybrids!

American Witchhazel

Hamamelis virginiana: American Witchhazel

This lovely resident of the uplands is sometimes called “winterbloom” thanks to its hardy flowers that appear in late fall and continue through the coldest days of the season. Witchhazel has long been known as a natural remedy for sunburn, scrapes, and other minor ailments. In folklore, it is also used as a divining rod to find water sources!


Waved Sphinx Moth

Ceratomia undulosa: Waved Sphinx Moth

The waved sphinx is a large moth with striking patterns that makes an impression when resting near porch lights and in gardens. It is common throughout the eastern US and westward to the plains states. Sphinx moths as a group are known for their ability to fly quickly – even up to 12 mph (19 kph). Some sphinx moths have developed the ability to hover and are sometimes mistaken for hummingbirds!


Sun Dogs

Parhelia: Sun dogs

What you see here is a parhelion grouping (from the Greek para=beside, and helios=sun), a phenomenon commonly known as sun dogs or mock suns. These bright spots occur when the sun’s rays shine through ice crystals in the upper atmosphere, refracting the light at specific angles. Circles and arcs can also occur. Sun dogs most frequently appear on either side of the sun, but spectacular variations can occur with more spots and arcs.


Wheel Bug

Arilus cristatus: Wheel bug

This insect is a species of assassin bug, which is an extremely important friend of gardeners. The wheel bug is named for its impressive armor, which resembles a saw-toothed blade. The wheel bug preys on common pests such as Japanese beetles, tent caterpillars, and cabbage worms. Its uses its fearsome proboscis to pierce other insects…so you should try to avoid picking one up, as you could get a nasty poke!


Stemonitis splendens
Stemonitis splendens

Stemonitis splendens: Chocolate tube slime mold

Amazingly, this organism begins its life cycle as white blobs of slime spreading across rotting wood. Only a few hours later, it transforms into a completely different form by sprouting tiny tubes covered with chocolate-colored spores. Slime molds, like their distant fungi cousins, are crucial links in the chain of decomposition, breaking down dead organisms to create nutrients and new habitat in the ecosystem.
