Rescued giant moths emerge from cocoons in Mexico's sprawling capital
MEXICO CITY: Two moths the size of a hand, their wings patterned with brown and pink around four translucent sections, mate for hours hanging from a line alongside cocoons like the ones they emerged from just hours earlier.
'When I get here and find this, I jump with delight,' said María Eugenia Díaz Batres, who has been caring for insects at the Museum of Natural History and Environmental Culture in Mexico City for nearly six decades.
The mating pair of 'four mirrors' moths as they're popularly known in Mexico, or scientifically as Rothschildia orizaba, are evidence that the museum's efforts to save some 2,600 cocoons rescued from an empty lot were worth the trouble.
The moths, whose numbers have fallen in Mexico City due to urbanization, have cultural relevance in Mexico.
'The Aztecs called them the 'butterfly of obsidian knives,' Itzpapalotl,' Díaz Batres said. 'And in northern Mexico they'd fill many of these cocoons with little stones and put them on their ankles for dances.'
These cocoons arrived at the museum in late December.
'They gave them to us in a bag and in a box, all squeezed together with branches and leaves, so my first mission was to take them out, clean them,' Díaz Batres said.
Mercedes Jiménez, director of the museum in the capital's Chapultepec park, said that's when the real adventure began since they had never received anything like this before.
Díaz Batres had the cocoons hung in any place she thought they might do well, including her office where they hang from lines crisscrossing above her table. It has allowed her to watch each stage of their development closely.
The moths only survive for a week or two as adults, but they give Díaz Batres tremendous satisfaction, especially when she arrives at her office and new moths 'are at the door, on the computer.'
So she tries to help them 'complete their mission' and little by little their species recovers.

How NEOM is rewilding Saudi Arabia and reviving ancient falconry traditions
RIYADH: As the world marks World Environment Day, a global celebration of nature and a call to protect our planet, attention turns to an ecological transformation taking place in northwestern Saudi Arabia. NEOM, the Kingdom's futuristic megacity project, is rapidly becoming a haven for biodiversity — and at the heart of this effort is a renewed commitment to falcon conservation. Under the banner of the Hadad Program, NEOM is working in partnership with the Saudi Falcons Club and other national entities to reintroduce native falcon species to the Arabian Peninsula, rebuild local ecosystems, and revive an ancient cultural tradition. The work being done in NEOM is about more than saving birds; it is about restoring balance to a landscape often misunderstood as barren and bringing nature back to the center of modern development. Since 1973, June 5 has been observed as World Environment Day. Led by the UN Environment Programme, it serves as a platform to raise awareness and prompt action on pressing environmental issues from climate change and pollution to biodiversity loss. Announced in 2017 as part of Saudi Arabia's Vision 2030 reform agenda, NEOM is a $500 billion mega-project designed to reshape the future of urban living, sustainability and technology. Encompassing 26,500 square kilometers of mountains, desert, and coastline along the Red Sea, NEOM's planners aim to build a zero-emission, high-tech region powered entirely by renewable energy. Yet beyond the cities of the future lies a growing commitment to the past — particularly in preserving and restoring the Kingdom's natural heritage. 'People tend to assume that this part of the world is an empty desert, but NEOM is stunning for its habitat diversity,' Paul Marshall, head of nature conservation at NEOM, told Arab News. Indeed, NEOM's terrain is anything but barren, from mountain peaks reaching 2,600 meters above sea level to oceanic depths plummeting 1.5 kilometers. In between are red sand deserts, canyons and caves, and spectacular shores with crystal-clear waters and coral reefs. This biologically rich region is home to creatures great and small: from hyrax, ibex and oryx to hedgehogs, gazelles and a wide variety of birds and insects. 'From those plants we have insects and mammals. Then, we have the large mammals, of course,' Marshall said. Before human encroachment, the region was even home to apex predators such as cheetahs, lynx and leopards. Now, through conservation, NEOM is seeking to recreate conditions that allow such species to return. 'For all of our biodiversity, it is still a fundamentally arid ecosystem,' he said. 'The species here have adapted to survive with very low rainfall and because of that, they are able to thrive despite the conditions.' The Hadad Program supports NEOM's rewilding strategy by reintroducing native falcon species, most notably the lanner and barbary falcons. 'This is a really exciting program,' Marshall said. 'It is one of many programs we are doing to restore the full ecosystem in the NEOM area.' Despite the climatic conditions, several types of plants were able to grow and uniquely adapt to different parts of NEOM's ecosystem. 'From those plants we have insects and mammals. Then, we have the large mammals, of course,' he said. He added: 'This is a really exciting program. It is one of many programs we are doing to restore the full ecosystem in the NEOM area.' Falcons used to be widespread throughout the whole of the Arabian Peninsula. But, through a combination of hunting and capturing for sports, in many places, Marshall said, that these animals are hard to find. Today, efforts are underway to bring them back. With the rich habitat and the efforts to safeguard the falcons, they are creating an environment where the species can be released with the best chances of survival. They successfully released eight pairs of barbary falcons, which are a very rare type; very few of them are left in the wild. 'We are committed to caring for falcons as a cultural and historical heritage and supporting all related activities through a set of regulations and organizational frameworks adopted by the club,' Talal Abdulaziz AlShammisi, CEO of the Saudi Falcons Club, told Arab News. 'This includes promoting and preserving falconry heritage, organizing falcon auctions, collaborating with universities, colleges, research centers and health institutions to conduct falcon-related studies and scientific research.' Falconry is not just a pastime in Saudi Arabia; it is a centuries-old tradition deeply woven into the fabric of national identity. 'Falconry has been practiced by our ancestors across the deserts of the Kingdom for centuries and today the country is home to thousands of falcons and passionate falconers,' said AlShammisi. 'Local species such as the lanner falcon and the barbary falcon are native to the Saudi environment and hold significant ecological value as essential components of environmental balance.' The barbary falcon, once on the brink of extinction in parts of the Arabian Peninsula, is now making a comeback. Thanks to the Hadad Program's careful release, rehabilitation and monitoring strategies, the birds are beginning to reclaim their place in Saudi skies. The initiative's success is underpinned by a network of partnerships. Area (square kilometers) of NEOM spanning mountains, desert and Red Sea coastline. NEOM is working with the Saudi National Center for Wildlife, the Saudi Falcon Club and the Special Forces for Environmental Security to monitor these falcons, to protect them and give them not only the best chances of survival but appearing and breeding. Soon, the first new generation of barbary falcons is expected to hatch in NEOM. While falcons are among the stars of NEOM's rewilding efforts, the program goes much further. More than 1,100 animals once absent from the region — including oryx, ibex, mountain gazelles and sand gazelles — have been reintroduced to help restore a natural ecological balance. The reintroduction of different species of animals is not only a victory for biodiversity but also a chance to restore natural food chains and ecological interactions that sustained this environment for millennia. With plans to extend across 95 percent of megacity project's total land area, the NEOM Nature Reserve represents one of the most ambitious conservation zones in the world. Through projects such as the Saudi Green Initiative and the Middle East Green Initiative, the Kingdom aims to plant billions of trees, reduce emissions, and protect vast swaths of land and sea. As World Environment Day shines a spotlight on the urgent need to protect and restore our natural world, NEOM stands as a compelling example of how large-scale development and ecological stewardship can go hand in hand.

US judge orders Trump administration to arrange return of Guatemalan deportee
A federal judge ordered the Trump administration on Friday to facilitate the return of a Guatemalan man who said he was deported to Mexico despite fearing he would be persecuted there, after officials acknowledged an error in his case. US District Judge Brian Murphy in Boston issued the order days after the Justice Department notified him that its claim that the man had expressly stated he was not afraid of being sent to Mexico was based on erroneous information. The Justice Department said last week that upon further investigation, officials were unable to identify any Immigration and Customs Enforcement officer who had asked the man, identified as 'O.C.G.,' about fears he had for his safety. Murphy, an appointee of Trump's Democratic predecessor Joe Biden, called the case a 'horror' and said that 'while mistakes obviously happen, the events leading up to this decision are troubling.' The ruling marks the latest instance of a judge ordering President Donald Trump's administration to facilitate the return of a migrant swept up in the Republican's efforts to carry out mass deportations as part of his hard-line immigration agenda, following a mistake in an individual's case. In a class action lawsuit filed by O.C.G. and other migrants, the judge had blocked the administration from swiftly deporting people to countries other than their own without first hearing any concerns they had about their safety. 'Due process is, in some sense, a binary - one either receives what the Constitution requires, or one does not,' Murphy wrote. 'It has been clear that O.C.G. did not receive what the Constitution requires.' The Department of Homeland Security, which oversees ICE, and the White House did not immediately respond to requests for comment. The government likewise made an error with Maryland resident Kilmar Abrego Garcia, who was deported to El Salvador in March despite an order protecting him from removal. He remains there, despite a judge ordering the administration to facilitate his return. Friday's ruling comes two days after Murphy, in the class action lawsuit case, concluded that the Trump administration had violated his earlier ruling by attempting to deport a group of migrants to South Sudan. According to his lawyers, O.C.G. is a gay man who fled Guatemala in 2024 after facing death threats based on his sexuality. He entered the United States through Mexico in May 2024. Murphy said that while an immigration judge in February found O.C.G. deserved protection from being returned to Guatemala, authorities two days later wrongly placed him on a bus to Mexico, where he had recently been raped and kidnapped. Trina Realmuto, a lawyer for O.C.G. at the National Immigration Litigation Alliance, said his legal team was 'elated' by Murphy's ruling and would work to facilitate a return plan. After arriving in Mexico, O.C.G. had to choose between waiting months in detention to apply for asylum in Mexico or return to Guatemala. He chose the latter and went into hiding, his lawyers say.
