New species of clearwing moth from Guyana discovered in Wales

It was discovered after two Welsh specimens were accidentally brought into Europe in a boot bag brought back from a photography trip to Guyana.

A new species of moth has been described far away from home following a cross-continent detective journey that included Natural History Museum scientists from separate fields, a budding young ecologist with a knack for community science, a globe-trotting photographer, and two moths new to science which travelled over 4,500 miles from their native country.

The species is a clearwing moth and has been named Carmenta brachyclados, in reference to a characteristically short hindwing vein. Despite having never been catalogued in its native country, Guyana, a surprising sequence of events led to its being described after being spotted flying around a home in Port Talbot, Wales.

In February this year, the new species was spotted flying around the home of ecologist Daisy Cadet and her mother, Ashleigh, a professional photographer. Captured by the moth’s striking appearance, which stood out as being out of the ordinary for a house moth in the UK during winter, Daisy uploaded an image to social media which set the chain of events into motion.

Daisy was referred to Natural History Museum lepidoptera experts, Mark Sterling and David Lees, having been advised she had stumbled upon something out of the ordinary by social media users. Mark and David started seeking a match of the Wales specimens in terms of appearance to the clearwing collection contained within the 13.5 million Lepidoptera specimens housed at the NHM – the world’s largest and most diverse collection.

Taking the investigation a step further, Sterling and Lees aided by the museum’s Jordan Beasley, carried out DNA sequencing on the moth and found that its closest match was a group of seed-feeding clearwing moths, Carmenta, which occur in Central America and South America. This finding prompted Daisy to look inside Ashleigh’s bag, which had accompanied her on a photography assignment in Guyana.

Two delicate pupal casings, still intact, were found among the mud from the boots she’d worn on the trip along with a small piece of woody vegetation with what looked like bore holes made by the caterpillars of the moths.

Mark Sterling, a Scientific Associate at the Natural History Museum, commented: “Clearwing moths are notoriously difficult to find, even by professional entomologists. They are even more difficult to rear from larvae or pupae, which usually dry out or go mouldy within a few days of collection.

“The chances of two clearwing moths from the Neotropics successfully emerging in South Wales, over three months after they arrived, in cold Welsh winter, and being preserved in good condition, is extraordinary.”

“The improbability of this event defies rational explanation. However, whilst in Guyana, Ashleigh was told that if she left an offering of tobacco to the jungle spirits she would be shown something beautiful from the jungle, so that is what she did. We conclude in the paper that it must have been very good tobacco.”

Dr David Lees, Senior Curator for Microlepidoptera at the Natural History Museum, added: “To add to the improbability of this story is the fact that due to the incredible piece of community science from Daisy, we have photographs of a living holotype (an original specimen which forms the basis of the name and description of that species), which is highly unusual.”

Along with now having a country of origin for this new species, they also had a small piece of the host plant on which the larvae had evidently fed. The plant fragment was sent to Natural History Museum botanist, Sandy Knapp, who advised it was likely to be a seed pod of a species of Mora, a suggestion confirmed by DNA sequencing by Jordan. A large leguminous tree, Mora excelsa grows in the jungles of Central America and South America.

The final step was to compare Daisy’s moth specimens to the vast number of species within the Carmenta genus – where only half of the 100 described species have been DNA barcoded. Using analyses of DNA and the specimens’ body plan compared to others on record, Mark and David concluded that this was indeed an undescribed species.

Mysterious new moth species discovered in Europe

The moth, named Mirlatia arcuata, by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.

European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11, 000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family described in the scientific journal ZooKeys tell a different story. The moth, named Mirlatia arcuata by a research team from Germany, Austria, and the United Kingdom, is one of the most remarkable discoveries in Lepidoptera of recent decades.

Decades-old UFO

In the early 1980s, Austrian amateur entomologist Robert Hentscholek collected three specimens of a moth species in southern Dalmatia, Croatia, which were integrated into his collection or given to colleagues without being identified. Decades later, the collection was sold to Toni Mayr, another hobbyist researcher from Austria, who immediately noticed the unusual insect that stood out from all known European species and couldn’t even be assigned to a known genus.

The collector was contacted to provide more information, and it turned out that a male and a female specimen of the same species had been given to another collector who had since passed away. The female specimen was rediscovered in 2015 in the collection of the Natural History Museum in Vienna, while the whereabouts of the other specimen remained unknown. The unique male was finally presented to the Tyrolean Federal State Museums by Toni Mayr.

In 2022, a research team was formed to identify this enigmatic moth, and it was finally described as a new genus and species in early November 2023. It was given the name Mirlatia arcuata, where Mirlatia is an aggregate of the stems of two Latin words that translate loosely as “bringing a surprise,” a reference to the surprising discovery of this curious new moth.

Cold-adapted or introduced?

The discovery of such a large and distinctive moth species in a well-explored region like southern Croatia might seem unlikely. However, according to researcher Peter Huemer of the Tyrolean State Museums (Ferdinandeum), who took part in the study, there was surprisingly little research conducted in that area during the moth’s flight season in March. “It’s possible that Mirlatia arcuata is a cold-adapted, winter-active species that would need to be sought in the middle of winter,” he says.

The hypothesis of introduction from other continents was discarded by the study authors for several reasons. Axel Hausmann from the Zoological State Collection in Munich examined all known moths from cold regions in the northern and southern hemisphere and could not identify a similar species from these regions. Furthermore, the collecting location in Podgora is not in close proximity to a port, and during the Yugoslavian era, the traffic in Dalmatian ports was rather limited. Also, Split and other Croatian ports were rarely visited by ships from other continents during the communist period. Additionally, Robert Hentscholek had never collected in the tropics, ruling out the possibility of a labeling error.

Many questions, few answers

Despite all efforts, the relationships of the new genus and species have not been definitively clarified. Even the assignment to the subfamily Larentiinae is not entirely secure and is based on a few features like wing venation. Initial genetic data from the mitochondrial COI barcode, as well as characteristics of the tympanal organ (auditory organ), point to a largely independent systematic position of the species. Further investigations of the entire genome could provide more clarity.

Even less is known about the biology of the new species, apart from the fact that its known habitat consists of coastal rock biotopes with Mediterranean vegetation. In March 2022, Slovenian lepidopterologist Stane Gomboc initiated a comprehensive search, but it turned out to be unsuccessful. It’s possible that the moth’s flight season has already ended due to climate warming.

The study authors hope they will soon rediscover Mirlatia arcuata and know more about its habitat requirements and biology.

New alpine moth solves a 180-year-old mystery

Butterflies and moths (order Lepidoptera) are one of the most diverse animal groups. To date, scientists have found as many as 5,000 species from the Alps alone. Having been a place of intensive research interest for 250 years, it is considered quite a sensation if a previously unknown species is discovered from the mountain range these days. This was the case when a Swiss-Austrian team of researchers described a new species of alpine moth in the open-access, peer-reviewed journal Alpine Entomology, solving a 180-year-old mystery.

Decades of research work

Initially, the team – Jürg Schmid, a full-time dentist, author and passionate butterfly and moth researcher from Switzerland, and Peter Huemer, head of the natural science collections of the Tyrolean State Museums in Innsbruck and author of more than 400 publications, needed a lot of patience.

Almost thirty years ago, in the 1990s, the two researchers independently discovered the same moth species. While they found it was similar to a moth of the leaf-roller family Tortricidae and commonly named as Dichrorampha montanana which had been known to science since 1843, it was also clearly different. Wing pattern and internal morphology of genitalia structures supported a two-species hypothesis. Moreover, the two were found at the same time in the same places – a further indication that they belong to separate species. Extensive genetic investigations later confirmed this hypothesis, but the journey of presenting a new species to science was far from over.

The Hidden Alpine Moth

To “baptise” a new species and give it its own name, scientists first have to check that it hasn’t already been named. This prevents the same species from having two different names, and essentially means looking at descriptions of similar species and comparing the new one against them to prove it is indeed unknown to science. In the case of this new moth, there were six potentially applicable older names that had to be ruled out before it could be named as new.

Intensive and time-consuming research of original specimens in the nature museums of Paris, Berlin, Frankfurt and London eventually led to the finding that all six ancient names actually referred to one and the same species – Dichrorampha alpestrana, which has been known since 1843 and had to be adopted as the valid older name for Dichrorampha montanana as having been described a couple of months earlier. Similarly, all other available names proved to belong to Dichrorampha alpestrana. The species discovered by Schmid and Huemer, however, was different, not yet named, and could finally be described as new to science. The authors chose to name it Dichrorampha velata – the Latin species name means “veiled” or “hidden,” pointing to the complicated story behind its discovery.

Lots of unanswered questions

The Hidden Alpine Moth is a striking species with a wingspan of up to 16 mm and a characteristic olive-brown color of the forewings with silvery lines. It belongs to a group of mainly diurnal moths and is particularly common locally in colorful mountain flower meadows. For now, we know that its distribution extends at least from Salzburg and Tyrol through southern Switzerland and the Jura to the French and Italian Alps, with isolated finds known from the Black Forest in Germany, but the researchers believe it might have a wider range in Central Europe.

The biology of the new species is completely unknown, but Huemer and Schmid speculate that its caterpillars may live in the rhizome of yarrow or chrysanthemums like other species of the same genus. As with many other alpine moths, there is a strong need for further research, so we can get a better understanding of this fascinating insect.

Rare footage of a new clearwing moth species from Malaysia reveals its behavior

Unique footage of a new species of clearwing moth has been recorded in a primeval rainforest in Peninsular Malaysia revealing the behaviour of this elusive insect.

Clearwing moths, which are day-flying insects belonging to the Sesiidae family, imitate bees and wasps. Apart from the common species considered as agricultural pests, these moths are known mainly from old museum specimens, stored on pins in forgotten drawers. In the wild, they are elusive creatures, rarely spotted and, hence, poorly studied.

Marta Skowron Volponi from the University of Gdansk, Poland, a PhD student specialising in entomology, teamed up with nature filmmaker and photographer Paolo Volponi, associated with the ClearWing Foundation for Biodiversity, to find these intriguing insects. The results of their studies were recently published in ZooKeys.

In their search for clearwing moths, they went deep into the virgin Malaysian jungle, where elephants, tigers, tapirs and other charismatic Southeast Asian animals roam, while dealing with the intense heat, humidity and countless blood-suckers.

In the end, however, their effort was worth it: on a bank of a crystal clear river, during the hottest hours of the day, the researchers discovered a new species of clearwing moth displaying behaviour known as mud-puddling.

“Mud-puddling is the process of sucking-up liquids in order to gain essential nutrients, such as salt or proteins”, explains Marta. “It has only recently been observed in clearwing moths and, similarly as in other Lepidopterans, it seems to be restricted to males”.

The newly discovered species was named Pyrophleps ellawi in honour of Marta and Paolo’s Malaysian friend EL Law who supported the team during their expeditions and who has a deep affinity for nature.

Curiously, rather than resembling a butterfly’s relative, the new moth looks like an insect from a whole different order. It mimics potter wasps.

“It has a slender body, long legs and transparent wings with a blue sheen in sunlight, similarly to some species of potter wasps”, says Marta.

Furthermore, while observing the moth in the wild, the authors noticed that it does not only look like a wasp – it also flies like one.

“There were potter wasps in the same area. In flight, the two insects were impossible to distinguish, they would always confuse us!”

The new species seems to be quite rare. During the authors’ three expeditions to Malaysia, they managed to see only eight individuals with each of them seen on a different day.

“So there we were: on our knees on a sandy beach, in the middle of the jungle, trying to film the 1.5 cm moth”, Marta recalls. “We didn’t have much time: a single clearwing would come around 2:00 PM and stay for several minutes only. We knew that once it flew away, we would not get another shot”.

“Could it be that their rarity is the reason why the behaviour of clearwing moths is practically unknown and why there are still new species waiting to be discovered?” the researchers wonder.

Portuguese moth’s mystery solved after 22 years

An unknown moth, collected from Portugal 22 years ago, has finally been named and placed in the tree of life thanks to the efforts of an international team of scientists. The moth was unambiguously placed in the family of geometer moths (Geometridae), commonly known as loopers or inchworms due to the characteristic looping gait of their larvae.

The new species description is published in the open access journal Nota Lepidopterologica, along with a taxonomic review of the genus Ekboarmia, thought to comprise four species in the western Mediterranean area.

The first specimen, a male, was found in 1995 in Lagoa de Santo André, south of Lisbon, near the Atlantic coast. Despite its unique appearance, the specialists did not find enough similarities with any other European species, making its classification impossible. When three females were finally found following an intensive search in 2009, the team of scientists hoped they would find enough evidence to solve the mystery.

“The discovered females had different wing patterns compared to the males, suggesting sexual dimorphism, adding another complexity in the identification. This new species could not have been classified on the basis of external characters alone,” explains Dieter Stüning from Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Germany.

In 2015, two specimens, a male and a female, have been DNA barcoded and recently became targets of detailed morphological examinations. DNA data played an essential role in demonstrating that the male and the female belong to the same species, whereas morphological structures finally provided unambiguous evidence to place the mystery moth in the geometrid genus Ekboarmia. The species name miniaria seemed appropriate to denote its small size. The tiny moth is the smallest in its genus whose other species are externally dissimilar.

Peder Skou from Denmark played a central role in the discovery of the species, tirelessly searching for more material to solve the questions. “Discovery of an undescribed and distinct macromoth from Europe is a rare occasion, because the continent’s fauna is probably the most exhaustively studied in the world,” explains Skou.

Pasi Sihvonen from the Finnish Museum of Natural History concludes: “Virtually nothing is known about the species. Altogether, only 11 specimens have been found between 1995 and 2011. Larvae of related species feed on juniper needles, which might also be the foodplant of the new species. We hope that the richly illustrated publication of the new moth will lead to new discoveries of this mysterious species. More data are needed, for instance, its conservation status cannot be evaluated due to insufficient life history and distribution data.”

New moth in Europe: A southern hemisphere species now resident in Portugal

As travelling in the 21st century is easier than ever, so is for species to make their way to new areas, sometimes increasing their distributional range, or even establishing whole new habitats. On the other hand, when they leave their natural predators and competitors behind, and find abundance of suitable resources somewhere else, they are running the risk of becoming invasive.

Nevertheless, such is not the case of a small, darkish brown moth from the southern hemisphere that is now resident in central Portugal. There, the species do not exhibit invasive behaviour, and so far has been only observed in very low numbers. The discovery is published in the open access journal Nota Lepidopterologica by an international research team, led by Martin Corley, CIBIO-InBIO, Portugal.

In 2012, Jorge Rosete, one of the co-authors of the study, spotted a female specimen that he could not identify near his house. When Martin took a look at it, he placed it in the concealer moth family (Oecophoridae), but was unable to recognise neither its species, nor its genus. It did not took long before a few more specimens were found, including males.

Initially, Martin thought the moth might originate from Australia, given the abundance of eucalyptus plantations in the area where it was found, and the fact that there are more concealer moth species in Australia than on any other continent. However, despite their efforts and contacts with other researchers, they failed to find an Australian species to match the Portuguese specimens. As a result, the mystery remained for the next four years, until a molecular study into moth DNA pulled the curtains.

A fragment of DNA, also called DNA barcode, matched three other genetically identical unnamed specimens, originally collected from South Africa, in the DNA database BOLD. Further collaboration with Alexander Lvovsky, Russian Academy of Sciences, allowed the assignation of the specimens to a species name: Borkhausenia intumescens, known from South Africa. However, it did not end there. Further research into museum collections showed that in fact this species had been previously described from Argentina as Borkhausenia crimnodes, and therefore should be named as such.

The origin of the Portuguese specimens remain a mystery, but it is evident that the species is now established in central Portugal. The larvae of other species in the same genus feed on decomposed plants, so this is likely the case with the moth species as well. It might be that it has entered the country through Figueira da Foz port along with imported timber from South America intended for the paper industry.

It is not known if this is a South African species that had first been transported to South America, and then – to Portugal, or if it is originally South American. It is also possible that it is not native in neither of these areas, and instead originates from another country, where it has not even been discovered yet. The moth favours warm temperate zones and potentially might appear anywhere in the world with suitable climate.

New species of moth named in honor of Donald Trump ahead of his swearing-in as president

Days before Donald J. Trump steps forward on the Inaugural platform in Washington to assume the role of the 45th President of the United States of America, evolutionary biologist and systematist Dr. Vazrick Nazari named a new species in his honour. The author, whose publication can be found in the open access journal ZooKeys, hopes that the fame around the new moth will successfully point to the critical need for further conservation efforts for fragile areas such as the habitat of the new species.

While going through material borrowed from the Bohart Museum of Entomology, University of California, Davis, Dr. Vazrick Nazari stumbled across a few specimens that did not match any previously known species. Following thorough analysis of these moths, as well as material from other institutions, the scientist confirmed he had discovered the second species of a genus of twirler moths.

While both species in the genus share a habitat, stretching across the states of California, USA, and Baja California, Mexico, one can easily tell them apart. The new moth, officially described as Neopalpa donaldtrumpi, stands out with yellowish-white scales present on the head in adults. In fact, it was in these scales that the author found an amusing reference to Mr. Trump’s hairstyle and turned it into an additional justification for its name.

Donald Trump’s flying namesake is announced only a month following the recently described species of basslet named after predecessor President Barack Obama, also published in ZooKeys. The fish is only known from coral reefs in the Papahānaumokuākea Marine National Monument, Northwestern Hawaii, a nature reserve which the 44th President of the United States of America expanded to become the largest protected marine area in the world.

Being a substantially urbanized and populated area, the habitat of N. donaldtrumpi is also under serious threat.

“The discovery of this distinct micro-moth in the densely populated and otherwise zoologically well-studied southern California underscores the importance of conservation of the fragile habitats that still contain undescribed and threatened species, and highlights the paucity of interest in species-level taxonomy of smaller faunal elements in North America,” says discoverer Dr. Vazrick Nazari. “By naming this species after the 45th President of the United States, I hope to bring some public attention to, and interest in, the importance of alpha-taxonomy in better understanding the neglected micro-fauna component of the North American biodiversity.”

1,541 snout moth species and counting in the United States and Canada

The present snout moth list contains a ten-percent increase in the number of species since 1983. For the last thirty-three years snout moth specialists in the United States and Canada have been describing species new to science and recording species new to these two countries. Scientists have also published studies resulting in major changes to the classification above the species level, for example by studying snout moth “ears” (tympanal organs) and utilizing genes to study their relationships.

This check list was compiled over a three-year period by Dr. Brian Scholtens and Dr. M. Alma Solis. Brian Scholtens is a professor at the College of Charleston, South Carolina, and M. Alma Solis is a research entomologist at the Agriculture Research Service’s Systematic Entomology Laboratory, and curator of the U.S. National Pyraloidea Collection located at the Smithsonian Institution, National Museum of Natural History, Washington, D.C. Their results have been published in the open-access journal ZooKeys.

“A check list is one of the most important pieces of research, with many applications,” says Dr. Solis. “Knowing the fauna of a geographic area makes it possible to track species and, in this case, potential invasive species. The caterpillars of snout moths are economically important worldwide as pests of planted crops for food or biofuel, of forest trees, and of stored products such as wheat and nuts.”

“Many species, for example, the stored product pests, occur worldwide, but others, such as pest species of grasses including corn, can be restricted or only exist in certain geographic areas,” the scientist further explains. “It is important to be able to recognize as soon as possible that a particular species is not native to the United States or Canada.”

Scientists use Latin scientific names as “unique tags” to communicate about the morphological or molecular identity and habits of a species. One of the functions of taxonomists is to determine if a species is new or if it has already been described. Historically, confusion is created when the same species is described more than once (called a synonym) in other parts of the world.

A regional check list such as this one and a worldwide check list can work together to reinforce precision in the definition and communication about species, especially decreasing confusion about synonyms. Most worldwide check lists exist as online databases that can be updated. Dr. Solis said that they had cited new discoveries relevant to the North American snout moth fauna found in GLOBIZ, or the Global Information System on Pyraloidea, an electronic list of over 15,500 snout moth species names for which she is a collaborator.

Get to know them faster: Alternative time-efficient way to describe new moth species

Having collected thousands of moth and butterfly species from across Costa Rica, famous ecologist Daniel Janzen, University of Pennsylvania, and his team were yet to find out many of their names. When they sought help from Dr. Gunnar Brehm, the taxonomist realised he needed too much time to describe species in the framework of an extensive revision of the genus, especially as there are still only a few biologists skilled to do this.

In the end, he found a way to revise the Neotropical looper moth genus Hagnagorafast and efficiently through avoiding wordy descriptions, but focusing on diagnostic characters, illustrated external characters, genitalia structures and DNA barcoding instead. His study is available in the open-access journal ZooKeys.

Having been put together back in the 19th century, most of the species within the Neotropical moth genus Hagnagora had been described by 1913. In modern days, it seemed necessary for the taxon to be revised. As a result, Dr. Gunnar Brehm herein publishes a “concise revision” comprising twenty species. It includes two species that have been revived from synonymy, two subspecies reinstated to a species level, four species excluded from the genus and the description of three new to science. In honour of the people who had funded the research, the new species have been named after them.

Following the revision, the research concludes not only the DNA molecules divergence between the separate species, but some subtle differences such as size, form of the wing blotches or the shape of the male genitalia.

Curious characteristic behaviour traits have also been noted within the genus. The representatives of the discussed genus fold their wings vertically while resting just like most butterflies and unlike the majority of related geometrid moths. Similarly, three of the revised species were noticed to be active during the day when they would often perch on moist substances like rotting plants, mud or dung, from whose fluids they would find vital nutrients.

The author stresses on the fact that taxonomists can hardly keep up with the pace inventories are being compiled, nor with the accelerating destruction of tropical rainforests. “Taxonomists therefore need to accelerate their workflows and try to make their papers useful not only to other taxonomists but for ecologists who need their support”, Dr. Gunnar Brehm says.

“What used to be one species ten years ago, known as Hagnagora anicata, is now regarded as a complex of six species, and more might be discovered in South American rain forests”, Brehm says. “Integrating information of molecules and morphology, as concisely as possible, appears to be one promising way to cope with the problem of slow taxonomy”, he explains in conclusion.

Immaculate white: New moth species preferring dry habitats is a rare case for Florida

Spreading its wings over the sandhills and scrub of peninsular Florida, a moth species with immaculately white wings has remained unnoticed by science until Mr. Terhune Dickel brought it to the attention of Dr. James Hayden of the Florida Department of Agriculture and Consumer Services. As a result of their research, published in the open-access journal ZooKeys, the authors have also included a key to facilitate the recognition of different pale-winged moths and their close relatives.

With its taste for much drier habitats such as the sandhills of peninsular Florida, the new species, called Antaeotricha floridella, is a noteworthy case among the moths and butterflies. This kind of endemism is, however, quite common among other groups of insects and spineless animals.

Initially confused with another very similar and widely distributed species, called Antaeotricha albulella, the herein described moth was found to be actually quite different when dissected by co-author Terhune Dickel.

After Mr. Dickel showed specimens to Dr. Hayden, they noticed that its forewings are immaculately white, unlike those of its close relatives within the pale-coloured endemics for the New World. Their wings tend to differ in colouration on a species level and are often spotted, however minute these contrasting patterns might be. While the new species has its forewings always in snow-white on the upper side and its hindwings – in pale gray, its kin, A. albulella, has either one or two black spots of black on its own forewings and white or pale-gray hindwings.

Currently, not much is known about the new moth species’ feeding habits. The evergreen sand live oak is the only plant that it has so far been confirmed to feed on. However, the researchers do not exclude the possibility that the new species could use a wider variety of oaks as hosts.

The occurrence of the moth exclusively in the dry areas of peninsular Florida fits an ecological pattern, and it is likely that more species, currently assigned under incorrect names, will be found in the state’s sandhills and scrub.
