(TMU) – A large blue butterfly that was previously extinct has been successfully reintroduced to the UK, with the pollinator repopulating large parts of the country after an absence of 150 years.

Some 750 of the large blue butterflies, which are marked by distinct rows of black spots on its forewing, have been spotted this summer around Rodborough Common in Gloucestershire, southwest England – a higher number than anywhere else in the world.

In 1979, the butterfly was declared extinct and hasn’t been seen in the Rodborough region for 150 years. The Large Blue is one of the rarest of Britain’s Blue butterfly species, reports BBC.

Last year, conservationists released some 1,100 larvae to the region after meticulously preparing the landscape for the butterflies’ return.

The globally endangered large blue butterfly has a unique life cycle that begins with tiny caterpillars tricking the area’s red ant population (myrmica sabuleti) into hauling them to their nest, while even “singing” to it, after which the parasitic larvae feast on ant grubs before emerging a year later as butterflies.

“In the summer when the ants are out foraging, nature performs a very neat trick — the ants are deceived into thinking that the parasitic larva of the large blue is one of their own and carry it to their nest,” said research ecologist David Simcox in a statement.

“It’s at this point that the caterpillar turns from herbivore to carnivore, feeding on ant grubs throughout the autumn and spring until it is ready to pupate and emerge the following summer.”

Controlling the red ant population was a crucial component of the project to reintroduce the blue butterflies.

For five years, a range of experts from the National Trust, Butterfly Conservation, the Limestone’s Living Legacies Back from the Brink project, Natural England, Royal Entomological Society and the Minchinhampton and Rodborough Committees of Commoners collaborated to prepare the area for the butterflies.

Cattle grazing was kept in check and the area’s scrub cover was reined in to help the area’s ant population, while wild thyme and marjoram plant growth was encouraged to ensure that the butterflies have their natural source of food and egg-laying habitats.

“Butterflies are such sensitive creatures, and with the large blue’s particular requirements they are real barometers for what is happening with our environment and the changing climate,” said commons area ranger Richard Evans. “Creating the right conditions for this globally endangered butterfly to not only survive but to hopefully thrive has been the culmination of many years work.”

The butterfly was reintroduced to the UK after caterpillars were brought to the country from Sweden in an ecologist’s camper van, writes The Guardian.

Experts now say that the large blue butterfly has “stronghold” sites around the country and have also naturally colonized areas across southern England, reports CNN.

The return of the rare large blue to the region marks one of the most successful insect reintroduction projects to date, and marks the culmination of a nearly four-decade conservationist effort in Europe.

“One of the greatest legacies of the re-introduction is the power of working together to reverse the decline of threatened species and the benefit the habitat improvements will have for other plants, insects, birds and bats on the commons,” Evans said.

A Louisiana family was shocked to find a dolphin swimming through their neighborhood in the aftermath of Hurricane Ida.

Amanda Huling and her family were assessing the damage to their neighborhood in Slidell, Louisiana, when they noticed the dolphin swimming through the inundated suburban landscape.

In video shot by Huling, the marine mammal’s dorsal fin can be seen emerging from the water.

“The dolphin was still there as of last night but I am in contact with an organization who is going to be rescuing it within the next few days if it is still there,” Huling told FOX 35.

Ida slammed into the coast of Louisiana this past weekend. The Category 4 hurricane ravaged the power grid of the region, plunging residents of New Orleans and upwards of 1 million homes and businesses in Louisiana and Mississippi into the dark for an indefinite period of time.

Officials have warned that the damage has been so extensive that it could take weeks to repair the power grid, reports Associated Press.

Also in Slidell, a 71-year-old man was attacked by an alligator over the weekend while he was in his flooded shed. The man went missing and is assumed dead, reports WDSU.

Internet users began growing weary last year about the steady stream of stories belonging to a “nature is healing” genre, as people stayed indoors and stories emerged about animals taking back their environs be it in the sea or in our suburbs.

However, these latest events are the surreal realities of a world in which extreme weather events are fast becoming the new normal – disrupting our lives in sometimes predictable, and occasionally shocking and surreal, ways.

Mom in LA Suburbs Fights Off Mountain Lion With Bare Hands, Rescues 5-Year-Old Son

A mother in Southern California is being hailed as a hero after rescuing her five-year-old son from an attacking mountain lion.

The little boy was playing outside his home in Calabasas, a city lying west of Los Angeles in the Santa Monica Mountains, when the large cat pounced on him.

The 65-pound (30 kg) mountain lion dragged the boy about 45 yards across the front lawn before the mother acted fast, running out and striking the creature with her bare hands and forcing it to free her son.

“The true hero of this story is his mom because she absolutely saved her son’s life,” California Department of Fish and Wildlife spokesman Captain Patrick Foy told Associated Press on Saturday.

“She ran out of the house and started punching and striking the mountain lion with her bare hands and got him off her son,” Foy added.

The boy sustained significant injuries to his head, neck and upper torso, but is now in stable condition at a hospital in Los Angeles, according to authorities.

The mountain lion was later located and killed by an officer with the California Department of Fish and Wildlife, who found the big cat crouching in the bushes with its “ears back and hissing” at the officer shortly after he arrived at the property.

“Due to its behavior and proximity to the attack, the warden believed it was likely the attacking lion and to protect public safety shot and killed it on sight,” the wildlife department noted in its statement.

The mountain lion attack is the first such attack on a human in Los Angeles County since 1995, according to Fish and Wildlife.

The Santa Monica Mountains is a biodiverse region teeming with wildlife such as large raptors, mountain lions, bears, coyote, deer, lizards, and snakes. However, their numbers have rapidly faded in recent years, causing local wildlife authorities to find new ways to manage the region’s endemic species.

Blue Whales Return to Spain’s Coast After Disappearing for 40 Years

Blue whales have been returning to the Atlantic coast of Spain after an absence of over 40 years in the region, when whaling industries drove the species to the brink of extinction.

Blue whales, which are the world’s largest mammals, had long disappeared from the region until the recent sightings.

The first was spotted off the coast of Galicia near Ons Island by marine biologist Bruno Díaz, who heads the Bottlenose Dolphin Research.

Another one of the majestic creatures was spotted the following year in 2018 and yet another in 2019. In 2020, two whales again made their return to the area.

It remains unclear as of yet as to why the creatures have returned to the area, but controls on local whaling industries are believed to play a role.

“I believe the moratorium on whaling has been a key factor,” Díaz remarked, according to the Guardian. “In the 1970s, just before the ban was introduced, an entire generation of blue whales disappeared. Now, more than 40 years later, we’re seeing the return of the descendants of the few that survived.”

Whaling had been a traditional industry in Galicia for hundreds of years before Spain finally acted to ban whaling in 1986, long after the blue whale’s presence in the region had faded away.

Some fear that the return of the massive sea mammals is a sign of global warming.

“I’m pessimistic because there’s a high possibility that climate change is having a major impact on the blue whale’s habitat,” said marine biologist Alfredo López in comments to La Voz de Galicia.

“Firstly, because they never venture south of the equator, and if global warming pushes this line north, their habitat will be reduced,” he continued “And secondly, if it means the food they normally eat is disappearing, then what we’re seeing is dramatic and not something to celebrate.”

Díaz said that while the data certainly supports this theory, it is too early to determine climate as the precise cause.

“It is true that the data we have points to this trend [climate change] but it is not enough yet,” he told Público news.

Another possibility is that the ancestral memory of the old creatures or even a longing for their home may offer an explanation, according to Díaz.

“In recent years it’s been discovered that the blue whale’s migration is driven by memory, not by environmental conditions,” he said. “This year there hasn’t been a notable increase in plankton, but here they are. Experiences are retained in the collective memory and drive the species to return.”

In recent years, researchers have found that migratory patterns are also driven by the cultural knowledge existing in many groups of species.

Researchers believe this type of folk memory, or cultural knowledge, exists in many species and is key to their survival.

A typical blue whale is 20-24 metres long and weighs 120 tonnes – equivalent to 16 elephants – but specimens of up to 30 metres and 170 tonnes have been found.
