Experts say 35% rise in acreage covered by migratory insects my reflect adaptation to changing climate
Mexican experts have said that 35% more monarch
butterflies arrived this year to spend the winter in mountaintop forests, compared with the previous season.
Experts say the rise may reflect the butterflies’ ability to adapt to more extreme bouts of heat or drought by varying the date when they leave Mexico.

They smell like sweet meat, destroy vacuum cleaners and are wreaking havoc across rural New Zealand.
An unusually wet summer has brought joy to farmers and grief to residents, as a plague of cluster flies descends on homes in the Canterbury and Wairarapa regions.

Invasive fire ants have used recent flooding in Queensland to expand their Australian invasion, teaming up and forming floating rafts with their bodies to allow them to survive for weeks at a time.
Eradication officers in Queensland have captured photos of the dangerous ants forming the rafts in flood waters.

Six new alpine species of New Zealand’s most unusual and beloved insect – the wētā – have been discovered, but it is a bittersweet victory, with another piece of research describing the threat global heating poses for their snowy mountain habitat.
Wētā belong to the same group of insects as crickets and grasshoppers, and there are between 70 and 100 species of wētā endemic to New Zealand. They are wingless and nocturnal, and some, including the wētāpunga, are among the heaviest insects in the world – comparable to the weight of a sparrow.

The British public have been asked to track flowering fruit trees to help determine whether climate change is changing blooming patterns, in one of the largest studies of its kind.
The University of Reading and Oracle for Research have developed a fruit recording website where citizen scientists can easily post their findings. People will initially be asked to record the flowering cherry and plum trees near them, with apple trees soon to follow.

The boarding of Uganda Airlines flight 446 from Entebbe to Dubai was momentarily disrupted at the end of last year when two of the passengers started hawking bush crickets in the aisles.
Their fellow travellers couldn’t believe their luck: nsenene are a prized delicacy in Uganda, but despite November usually being peak season for the insects, there had been hardly any around.

A room swarming with thousands of giant, exotic creepy-crawlies may sound like your worst nightmare (or one of Ant and Dec’s Bushtucker Trials on I’m a Celebrity). It is also the starting point for Bug Out, the latest bizarre true-crime documentary series, which is set in the US’s first bug zoo, the Philadelphia Insectarium & Butterfly Pavilion. Prepare for a mystery with more twists than a worm colony.
The show focuses on the moment in August 2018 when the museum’s boss, Dr John Cambridge, arrived at work and did a double take when he realised his room, that ought to have been full of critters, was suddenly empty. Glass tanks were upended, shelves bare, displays cleared out. Thousands of live bugs, worth an estimated $50,000 (£38,000), had been stolen. It was the biggest insect heist in history.

Over Christmas and the new year, three of the world’s leading naturalists died. Thomas Lovejoy, a conservation biologist credited with popularising the term “biodiversity” and a passionate defender of the Amazon, died on 25 December. A day later, Edward O Wilson, known to many as the “modern-day Darwin”, died in Burlington, Massachusetts. On 2 January, Richard Leakey, a world-renowned Kenyan conservationist who helped establish Africa as the birthplace of humankind, died at his home in Nairobi.
From presidents to undergraduate students, thousands have paid tribute to the three men, whose achievements range from developing theories on forest and island ecosystems to reforming the Kenyan civil service and devising proposals to protect half the planet for nature. Alongside grand accomplishments, which were sometimes controversial, their passing has been a chance to reflect on the small and the mundane: fleeting interactions that inspired careers, kind words that propelled research projects, and generosity of spirit that has helped amplify the voices of those that practise and produce science.

In 2013, Syrian beekeeper Ryad Alsous drank his last cup of mint tea on the balcony of his flat in Damascus. He was about to leave the city where he had spent his whole life and move to Britain. Eight years later, he is again drinking mint tea made in the same flask but this time in Huddersfield. The flask is the only item he still has from his home in Syria. He is talking about the moment he left. “It was very difficult. And also full of hope,” he says.
His block of flats had been bombed twice, and explosions in the eastern part of the city were happening daily. On the day he left, a loud bang nearby caused the doves perched on his balcony to briefly flutter into the air. He had been feeding the birds for years and realised they would have no one to look after them once he left.

If you hold a Christmas beetle – small, brown, mechanical – in the palm of your hand, it moves as though under a spell. The spell commands it to keep walking, to burrow its surprisingly strong legs endlessly forwards, like the end of the year growing steadily nearer and just as steadily receding.
In Europe, Christmas beetles are called “cockchafers”. In the year 1478, they appeared in a French court to stand trial on the charge of having been sent by witches to destroy the laity’s crops (and jeopardise the church’s tithes).

A surge in mosquitoes, spiders, termites, rodents – and mould – has hit eastern Australia, in what appears to be a fitting end to 2021.
The wet weather caused by the latest La Niña event has helped flush out creatures that may typically burrow or live underground into the open and inside people’s homes.

More than 14,000 species of invertebrate lost habitat during Australia’s 2019-20 bushfires, according to a post-fire analysis that has recommended a doubling of the number of species listed as threatened.
The research, prepared for the federal government by scientists with the national environmental science program (NESP), found the number of insects, spiders, worms and other invertebrates affected by the disaster was much greater than the tally of vertebrates impacted.

What will biodiversity loss mean for drug discovery?
Traditionally used as a painkiller for headaches, snowdrops are now known to slow the onset of dementia. In the 1950s, a natural alkaloid called galantamine was extracted from the bulbs. Today, a synthesised version of this is used to treat Alzheimer’s disease and scientists are investigating further to see if snowdrops might also be effective in the treatment of HIV.
However, over-harvesting has resulted in many snowdrop species becoming threatened. The snowdrop isn’t alone – plants are an abundant source of potential new medicines, often providing us with chemical templates for the design of novel drugs. Yet scientists across the globe say unsustainable use of wild medicinal plants is contributing to biodiversity loss and could limit opportunities to source medicines from nature in the future.

The devastating 2019–20 bushfires had a significant impact on native Australian bees, threatening 11 species, according to new research.
Australian scientists have analysed the effect of the fires on 553 Australian native bee species – one-third of all bee species discovered in the country to date.

Many readers have noticed wildflowers thriving in urban areas as city councils decide to let grass grow wild. These colourful little patches may seem like window dressing in the face of vast decline, but across the world people are welcoming wildlife into cities, where more than half of us live. Here is a look at 10 of the most exciting and innovative urban biodiversity projects popping up.

In Quentin Dupieux’s Mandibles, a pair of chuckleheads called Manu and Jean-Gab (think Dumb and Dumber, but French) steal a Mercedes and find, in the boot, a housefly the size of a pitbull. They name it Dominique and train it to rob banks. At no point do they find it scary, even after it eats a dog. It’s so endearing, you will share their feelings.
This is a turn up for the books, since flies in cinema are more usually signifiers of death, decay and evil. Sometimes, as when Annie Graham goes up to the attic in Hereditary, their presence presages the discovery of a cadaver. They buzz symbolically around the grubby cheesecloth-wrapped bundle in Bring Me the Head of Alfredo Garcia, while Father Delaney’s attempts to bless the cursed house in The Amityville Horror are thwarted by demonic bluebottles. In Phenomena, Jennifer Connelly plays a schoolgirl insect-whisperer who can summon flies for protection, but that doesn’t save her from getting submerged up to her neck in maggots. In the bonkers Indian action-fantasy Eega, a man murdered by his love rival is reincarnated as a vengeful housefly, but fusing your molecules with those of a Musca domestica is more likely to end in loss of vital anatomical parts, as happens in both the 1958 and 1986 versions of The Fly. (Help meeee!)

“Eco-friendly” LED streetlights produce even worse light pollution for insects than the traditional sodium bulbs they are replacing, a study has found.
The abundance of moth caterpillars in hedgerows by rural roads in England was 52% lower under LED lights and 41% lower under sodium lights when compared with nearby unlit areas.

Washington state has confirmed its second “murder hornet” sighting of 2021 – the first glimpse of a live one, officials reported.
A statement released by the Washington state department of agriculture (WSDA) confirms the first report of a live Asian giant hornet in the state this year.

For five days in the late summer of 2019, doctors battled to bring down John Hayden’s high fever.
Hayden’s sudden onset of symptoms, including high fever, had everyone stumped, said his daughter Anne Hayden, and his body seemed to fail to respond to any treatment. He succumbed to the inexplicable illness just after Labor Day, his family at his side.

Scientists have successfully wiped out a population of malaria-transmitting mosquitoes by using a radical form of genetic engineering to render the females infertile – in the most advanced and largest ever test of use of the technology to fight the disease.
As well as bringing fresh hope in the fight against one of the world’s biggest killers, the study lays the foundations for further trials of gene-drive technology, which could mean self-destroying mosquitoes being released into the wild within 10 years.
