Gardeners urged to ‘keep it local’ when creating a wildflower meadow

Posted on by

Experts say neighbourhood varieties will suit an area’s pollinators, and that caution is needed when buying generic seed mixes

Gardeners hoping to establish a wildflower patch in their gardens should be wary of generic seed mixes and stick to local blooms to best serve wild pollinators, experts have said.

Conservationists are urging people to source not just native wildflowers but to find out what grows naturally in their neighbourhood by getting out in their area and looking for inspiration in existing meadows, verges and nature reserves. They should then use this as a guide to ensure they are collecting or buying the most suitable wildflowers for their gardens.

Field of fresh cow pats welcomes first dung beetles to be rewilded in France

Posted on by

Sixty of the keystone species released near Bordeaux to feast on waste from wild cattle and help restore a vital habitat on the Atlantic coast

In a forest clearing filled with cowpats, French history is being made: the country’s first translocation of dung beetles in a nature reserve near Bordeaux.

With the same pomp and ceremony afforded to the release of an Iberian lynx or a European bison, about 60 “ball rolling” insects were brought to the marshy forests of Étang de Cousseau in south-west France on Wednesday to restore a vital ecosystem function on the Atlantic coast.

Bogong’s back: La Niña rains help moth numbers recover from near extinction

Posted on by

Decimated by relentless drought, the population of the common Australian insect is recovering but remains fragile

The bogong moth population has started to bounce back after nearing extinction but the insect’s future remains fragile, a new report has found.

The Australian Conservation Foundation interviewed a number of scientists who collect data on bogong moth populations, finding that experts agree the numbers have increased this season, likely thanks to the deluge brought on by three consecutive La Niña years.

Burgundy insect farm ramps up production to offer a meat-free future

In a box-like building on an out-of-town industrial estate in Burgundy, trays of Alphitobius diaperinus – otherwise known as the lesser mealworm – are being fattened up by robots then cooked, dried and turned into protein-rich powder and oil.

This is the headquarters of Ÿnsect a French company that is building the world’s largest insect farm, to open at the end of the year in preparation for what the French company believes will be a large increase in demand for a healthy alternative to meat.

Buzz stops: bus shelter roofs turned into gardens for bees and butterflies

Posted on by

Bee bus stops first appeared in the Dutch city of Utrecht. Now the UK is planning for more than 1,000 and there is growing interest across Europe and in Canada and Australia

Butterflies and bees are getting their own transport network as “bee bus stops” start to pop up around UK cities and across Europe. Humble bus shelter roofs are being turned into riots of colour, with the number of miniature gardens – full of pollinator-friendly flora such as wild strawberries, poppies and pansies – set to increase by 50% in the UK by the end of this year.

Leicester is leading the charge with 30 bee bus stops installed since 2021. Derby has 18, and there are others in Southhampton, Newcastle, Sunderland, Derby, Oxford, Cardiff and Glasgow. Brighton council installed one last year after a petition was signed by almost 50,000 people.

With stealth followed by speedy acrobatics, Euryopis umbilicata can successfully catch banded sugar ants twice its size

A mid-air cartwheel, the judicious use of sticky silk and a quick rappel down a tree, all in the blink of an eye: researchers have identified how the Australian ant-slayer spider captures prey twice its size.

The acrobatic behaviour of the Australian ant-slayer spider, Euryopis umbilicata, as it hunts and eats banded sugar ants has been documented by scientists for the first time.

US farmers face plague of pests as global heating raises soil temperatures

Milder winters could threaten crop yields as plant-eating insects spread northwards and become more voracious, researchers say

Agricultural pests that devour key food crops are advancing northwards in the US and becoming more widespread as the climate hots up, new research warns.

The corn earworm (Helicoverpa zea) is considered to be among the most common farm pests in the US, ravaging crops such as maize, cotton, soya and other vegetables. It spends winter underground and is not known to survive in states beyond a latitude of 40 degrees north (which runs from northern California through the midwest to New Jersey), but that is changing as soils warm and it spreads to new areas, according to research led by North Carolina State University.

Aid projects in DRC and Zimbabwe encourage rural inhabitants to eat insects rich in vitamins and minerals

UK aid spending is encouraging hunger-stricken Africans to eat insects, with projects aiming to develop the practice in the Democratic Republic of the Congo and Zimbabwe.

Edible insects have long been touted as a resource-efficient source of protein, requiring less land and water than conventional livestock. However, taste and cultural resistance have proved to be stumbling blocks in extending the practice in many parts of the world.

Rare orchid flourishes in Charles Darwin’s gardens after two-year project

Posted on by

Unusually the violet helleborine is only pollinated by wasps and is thriving thanks to nectar that is irresistible to the insects

A rare orchid that reproduces by getting wasps drunk is thriving in the gardens of Charles Darwin’s house after a two-year restoration programme.

The violet helleborine is entirely pollinated by wasps, which are usually not perceived to be the best pollinators. They’re regimented and meticulously clean themselves, scientists say, which makes the process of pollination a fairly futile prospect – there’s nothing for the pollen to cling to.

Insect’s journey probably began in west Africa on vessel that sailed from La Rochelle in 1743 to Guinea

An 18th-century cockroach named Peri, discovered in the ledger of a French slave-trading vessel, has become a surprise addition to the National Archives after the book was opened for the first time in more than two centuries.

The insect’s journey began onboard the slave-trading vessel that sailed from La Rochelle in 1743 for the Guinea coast. The crew later boarded a different vessel in modern-day Haiti bound for France, taking the ledger with them. But that ship was seized by British privateers during the war of the Austrian succession and sent into Plymouth.
