Happy Moth Week! National Moth Week is an annual event that celebrates the diversity and magnificence of moths. By partnering with online biological databases, National Moth Week encourages everyone to become a citizen scientist by helping map moth distributions and provide information about these amazing species.

BHL is celebrating moth week by highlighting select species gleaned from one of our favorite BHL books: Butterflies and Moths: Shown to the Children (1910), by Janet Harvey Kelman, with descriptions by Rev. Theodore Wood.

Satisfy all your moth curiosity with free moth images from BHL in our Flickr Moth Collection and books on moths in BHL. Learn more about Moth Week and find out how you can get involved.

Death’s Head Hawk (Acherontia atropos)
There are three species of Death’s Head Hawk moths, but the European species is the best known. Characterized by the skull-shaped markings on its thorax, these are very large moths, with wingspans of 3.5-5 inches. The moth is capable of “squeaking” vocalizations, and commonly raids beehives for honey. By mimicking the scent of bees, it is able to prowl through the hives unmolested.

The moth’s association with death extends to its name. The genus name, Acherontia, is derived from the river Acheron in Greek mythology – one of the five rivers of the underworld associated with pain. The species name, atropos, comes from the name of one of the Greek Moirai, goddesses of fate and destiny.

Fun Quote from Butterflies and Moths
“And if you meet with [the Death’s Head Hawk], and pick it up, you will be surprised to find that it can squeak quite loudly! Stranger still, the chrysalis can squeak too, and so can the moth ! Indeed, if you pick up a Death’s Head Hawk Moth it will go on squeaking very much like a mouse all the time that you hold it in your hand!” (pg 39)

Wood Leopard (Zeuzera pyrina) 
Though found primarily in Europe and northern Africa, the Wood Leopard was introduced to America prior to 1879 and can now be found from Maine to Pennsylvania. With a wingspan measuring from just over 1 to just over 2 inches, this species boasts a distinctive, fury white thorax with six black spots and Dalmatian-esque black and white wings.

Fun Quote from Butterflies and Moths
“You may sometimes see [the Wood Leopard] resting on the trunks of trees in July and August. Then, if you examine the tree-trunk carefully, you are almost sure to find the entrance to the burrow out of which it came; for the caterpillar of this moth is one of those which feed on the solid wood of trees. The female moth lays her eggs in the crevices of the bark, and as soon as the little caterpillars appear they nibble their way into the trunk with their powerful jaws, and there live for several months, burrowing backwards and forwards, day after day, till sometimes the wood is almost honeycombed with their tunnels.” (pg 50)

The Puss Moth (Cerura vinula)
Found throughout Europe, North Africa, and temperate Asia, the Puss Moth has a 2-3 inch wingspan and feeds on willows and poplars. With a flight period extending from April to August, the pupa winters the cold months in a wood-reinforced cocoon. The light green caterpillar exhibits a defensive pose that involves rearing its bright-red head and extendable flagellae on its rear (as seen in illustration). If a predator fails to regard this warning, the caterpillar will squirt formic acid.  

Fun Quote from Butterflies and Moths
“This fine and handsome moth is called the ‘Puss,’ because, when its wings are closed, it looks rather like a brindled cat. And there are two or three smaller moths which are a good deal like it; so these are known as ‘Kittens.'” (pg 79).

The Old Lady (Mormo Maura)
Found throughout northwestern Africa and Europe, the “Old Lady” or “Black Underwing” moth measures about 2-2.5 inches in wingspan. Found mostly near water, it hides by day and is not particularly attracted to light. It is, however, attracted to sugar, and feeds on the leaves of various fruit trees.   

Fun Quote from Butterflies and Moths
“If you were to ask me why this moth should be called the ‘Old Lady,’ I am not quite sure that I could tell you. But I think the reason must be that old ladies mostly dress in dark grey, or dark brown, or black, which are just the colours of the wings of the moth.” (pg 88)

Privet Hawk Moth (Sphinx ligustri), which will hiss at you if you make him mad. http://biodiversitylibrary.org/page/42193534

Ohio, 1854. A dense, black shadow begins to creep across the northern edges of the horizon, slowly but incessantly blotting out a bright cerulean sky. Residents take notice, and pour out of their homes and businesses to stare in wide-eyed awe and trepidation at the phenomena edging towards them.

Hours pass, and the sky is hurled into unwavering darkness. Finally, as the day fades, the sun itself succumbs to this nameless power.

Men and women fall to their knees in prayer, begging for deliverance from the Revelational apocalypse. A thundering roar, like the beating of a million drums, assaults the kneeling petitioners, and their fingers turn icy as an arctic gale whips around their bodies.

A lone figure, hunting rifle in hand, stands atop a hill and stares at the pitiful scene before him. Shaking his head, he lifts his muzzle, peers straight and true through his sights, and pulls the trigger. Dozens of shapes, like tiny meteors, break away from the mass overhead and plummet towards the earth. Swinging his weapon over his shoulder in satisfaction, he picks up a burlap sack and swaggers towards the fallen celestial bodies. As he stoops and retrieves one of the mysterious figures, a pair of slate wings unfurls. He stuffs the Passenger Pigeon unceremoniously into his bag and moves on to the next bird.

Mark Catesby’s 1754 illustration of the Passenger Pigeon is thought to be the first published depiction of the species. The Natural History of Carolina, Florida, and the Bahama Islands. v. 1. 1754. http://biodiversitylibrary.org/page/10900155

Ohio, July 1914. A ten year old boy sidles through a mob of men, women, and children ogling exotic animals at the Cincinnati Zoological Garden. Desperate to find a quite haven to escape the crowd, the child slips around the corner and finds himself staring directly into a pair of bulging eyes. Startled, he jumps back, and the eyes tilt sideways in response, as though curious about this new creature.

Brow furrowed, the boy takes a timid step forward, mesmerized. What he had momentarily mistaken for the glare of some ferocious predator he realizes is simply the quizzical stare of a rather drab looking bird. Her feathers, ever so slightly ruffled, are an unimposing brown dotted with gray and black. She stands with her back to him, her head facing him atop a neck turned 180 degrees like a broken porcelain doll.

“So I see you found Martha,” a deep voice rumbles behind him.

Startled again, the boy turns and finds a gray-haired, mustached zoo keeper standing behind him.

“Martha?” he responds, confused.

“Martha, our passenger pigeon. She’s the last of her kind, you know. When she dies, a whole species will go extinct.”

Frowning, the boy turns again to look with new appreciation into the eyes of this modest animal. Unexpectedly, he is filled with sorrow. She may not be as exciting as a dinosaur or as fierce as a saber-tooth tiger, but she looks very innocent and very lonely.

A surge of purpose rises up in his chest.

“Can’t we do anything to help her?” he asks fervently.

The man shakes his head sadly.

“It’s too late. Maybe we could’ve done something forty years ago, when people first realized they were in trouble. But now, there’s nothing we can do.”

The boy turns back despondently. She was the very last of her species, and it was too late to do anything to save her. Why hadn’t anyone done something when there was still time?

Losing interest in the boy, Martha turns her head, puffs up her chest, and tucks her beak tightly into her breast. She’d had enough of humans for one day.

The Fall of a Mighty Empire: The Passenger Pigeon

Two hundred years ago, the Passenger Pigeon (Ectopistes migratorius) was the most abundant bird species in North America. A population numbering in the billions, as much as 40% of all land birds on the continent shared the same genome as Martha. Migrating flocks were so large that they literally blocked out the sky, stretching up to a mile wide and 300 miles long and taking 14 hours to pass a single point. Flocks were so densely packed that a single shot could bring down dozens of birds. The beat of up to 3.5 billion pairs of wings literally created its own cold front below, and those unaccustomed to the marvel feared the end of the world was upon them.

So many Passenger Pigeons would pile into a single tree that branches would snap off or entire trees would tumble to the forest floor. The one in this picture looks to be leaning precariously… The Birds of North America. 1903. http://biodiversitylibrary.org/page/35159567

Nesting colonies were just as large, covering several hundred square miles of forest. A single tree often contained up to 100 nests, causing many to topple over at the sheer weight of an aviary kingdom. By the end of the nesting season, blankets of pigeon droppings several inches thick saturated the forest floors. However, while colonies were staggeringly massive, a mating pair of passenger pigeons produced only one, occasionally two, eggs per season.

The Passenger Pigeon was nearly twice as large as the common city pigeon, with males averaging 16 inches in length and up to 12 ounces in weight. Frames built for speed and maneuverability, the birds could reach up to 60 mph, making them ideal targets for not only hunting parties but simple target practice. The onset of large-scale commercial hunting and railroads for distribution turned a sustainable hunting practice into a frenzied genocide. In 1869, Van Buren County, Michigan, alone shipped 7.5 million passenger pigeons to the east, where they sold for mere pennies.

The dangerous decline of the species was noted as early as the 1850s, but cheap meat and a seemingly endless supply of birds dampened any resolve to implement hunting restrictions. In 1896, a majority of the last wild flock of 250,000 birds were killed during a sporting event heralded as the “last chance to shoot the passenger pigeon in the wild.” On March 24, 1900, a 14-year old boy killed the last known wild Passenger Pigeon in Pike County, Ohio.

From billions to none in less than 100 years.

Remembering Martha

Martha is ready for her close-up! The Smithsonian Institution has created a 3D scan of Martha and made it available as an interactive 360 view online. Image author: Donald E. Hurlbert, 6/23/2014. Image copyright Smithsonian Institution.

Martha the Passenger Pigeon is perhaps one of the most famous animals in the world, for she is a tangible reminder of the human capacity to decimate biodiversity. At nearly 30 years old, Martha, the very last of her species, died at the Cincinnati Zoological Garden at about 1pm on September 1, 1914. Immediately after her death, she was entombed in a 300 pound block of ice and shipped to the Smithsonian, where she was taxidermied.

In remembrance of the centennial of her death, Martha is on display at the Smithsonian’s National Museum of Natural History until October, 2015, as part of  the joint BHL/Smithsonian Libraries exhibit: “Once There Were Billions.” The exhibit documents the tragic histories of four extinct North American birds: the Passenger Pigeon, Great Auk, Heath Hen, and Carolina Parakeet.

Millions of people have rallied to commemorate the Passenger Pigeon this year, and help raise awareness about endangered species, extinction, and the impact of human activity on healthy ecosystems. The “Fold the Flock” initiative is an effort to recreate the staggering passenger pigeon flocks of the 19th century through origami pigeons. “The Lost Bird Project” has created a film and book to investigate extinction and memory. Also as part of the project, Todd McGrain has crafted stunning bronze sculptures of extinct birds, including the passenger pigeon, which are on display across America.

Other initiatives like Project Passenger Pigeon, the film From Billions to None, and a multitude of exhibits nationwide are working to raise awareness about extinctions and excite action to prevent future biodiversity calamities.

How Can Historic Literature Help Modern Scientists Save Species?

Reports, illustrations, and photographs in historic literature and taxidermied specimens are the only remaining record we have of extinct species. Thus, preserving this knowledge is important simply as a means of documenting the biodiversity we have lost. But retaining and providing access to this legacy literature is not just about creating a memorial for extinct species. It’s also about helping to prevent future extinctions.

Historical records allow scientists to study the morphology, behaviors, habitats, diet, and breeding patterns of species, which help determine where those species might be vulnerable and inform strategies for rehabilitating endangered populations. Similar information about extinct species, and an evaluation of the circumstances that led to their demise, can help scientists identify threats to similar species. Records of migration pathways and changes in distribution patterns allow scientists to provide educated recommendations to policy makers about the lands and species to protect.

Without a concrete evaluation of earth’s biodiversity history, and an understanding of the mistakes we have made in the past, we are doomed to repeat our darkest moments. But just as humans have a capacity to annihilate a species, so have we the power to save one (take the American Wolf, for example). Supporting initiatives like the Biodiversity Heritage Library gives scientists, policy makers, and concerned citizens the information they need to protect life on earth. Take a look at what your donation can do, and we hope you’ll consider giving a tax-deductible gift today.

Once There Were Billions, the new Smithsonian Libraries/BHL exhibit at the National Museum of Natural History.  The Passenger Pigeon on the left, with her back to the viewer, is Martha, the last Passenger Pigeon that died 100 years ago in 1914.

You are living in the midst of earth’s sixth great extinction event. You’ve been living in it since you were born. So have your parents, your grandparents, your great-great-great-great-grandparents, and all of your ancestors for about 10,000 years. It dates back to the extinction of the mammoths and has been increasingly accelerating as human actions and climate change reshape the balance of our planet.  Within the next century, 75% of the conservatively estimated 8.75 million species on earth may be extinct.

When many of us think of extinctions, we think of the countless species disappearing in the Amazon rainforest, the ocean’s coral reefs, or the forests of South-east Asia. But the truth is that extinctions happen in every corner of the globe. Some are noticeably notorious, others occur without us even knowing that the species existed in the first place. One of the most infamous North American extinctions is the demise of the Passenger Pigeon.

Gilbert Borrego, co-curator of the Once There Were Billions exhibit.

The fate of the Passenger Pigeon, and three other extinct North American bird species (Great Auk, Carolina Parakeet, and Heath Hen), are the focus of the new joint BHL/Smithsonian Libraries‘ exhibit at the National Museum of Natural History: Once There Were Billions.

Positioning the Great Auk in the exhibit.

“The most challenging part of the exhibit was narrowing down our source material,” said Borrego. “The topic [of the exhibit] was originally much more general, focusing on extinct species. We knew Martha the Passenger Pigeon was to be included, but we looked at many other types of animals and plants before settling on the plight of birds from North America.”

And voila! This specialized hub for extinction education opened to the public this past Monday, June 24, 2014, and will remain open until October, 2015.
