New species of invasive flatworm discovered in three southern US states

Amaga pseudobama was first spotted in 2020 in North Carolina and has now spread to Florida and Georgia

A new species of invasive flatworm has been discovered in the United States and has been found in several states in the south, according to a new paper.

The species, named Amaga pseudobama, was discovered by an international team of researchers and first spotted in 2020 in North Carolina. It is thought to be native to South America.

More wildlife-friendly farming needed to stop decline of insects in Britain, says report

Populations of bees, spiders, ground beetles and hoverflies have declined twice as fast on land farmed for crops in the past 30 years, despite funding for more sustainable farming methods

Conservation measures over the past 30 years have failed to stop the decline of insects on British farmland, a new report shows. Populations of bees, spiders, ground beetles and hoverflies have disappeared twice as fast in areas intensely farmed for crops, according to the paper, which looked at citizen science data on more than 1,500 invertebrate species.

Although there was a push to intensify agriculture after the second world war, since the early 90s more sustainable and wildlife-friendly farming practices have emerged, with EU agri-environment funding made available for farmers to plant hedgerows and wild flowers, alongside better regulation of pesticides. However, these have not managed to stem biodiversity loss.

‘Spectacular’ spiny crayfish samples rec amid Lismore floods key to mapping species

Australia Museum says 20-year-old collection will help understand and conserve threatened animals, which are sensitive to climate change

As floods devastated Lismore, a group of ecologists waited anxiously for a break in the weather so they could move an important scientific collection of “spectacular” spiny crayfish to a new home at the Australian Museum.

The samples of the crayfish were collected more than 20 years ago from deep within the rainforests of north-eastern NSW and southern Queensland by Dr Jason Coughran, a freshwater ecologist.

Slug numbers appear to shrivel after UK heatwave

Zoologists say they have never seen this low a number, after unprecedented hot weather

As dewy dawns break across the UK’s pumpkin patches and allotments, gardeners across the land are waking up to the absence of at least one slippery pest. Slug numbers appear to have shrivelled as a result of the ongoing drought.

“I went to survey a woodland site last week and it took me over 30 minutes to locate a slug. Usually, I would expect to find them under almost every log in that habitat,” said Jake Stone, a zoologist at the University of Cambridge. “I thought that there would be fewer around, but I’ve never seen this low a number. But I suppose that’s to be expected, because it’s rarely been this hot and dry.”

Country diary: my swim with a bloodthirsty hanger-on

Hartsop, Cumbria: I look down and notice a slug-sized, dark brown invertebrate clinging to my leg

A good September day can feel more like true summer than any other time of year, and this sunny, sultry Sunday in the Patterdale valley is an excellent example. The landscape has eased into a settled maturity: the hedgerows are full of dark fruits, the rowans are full of lipstick-red berries, and juvenile sparrowhawks call out from woods of deep, well-aged green. This late-summer lull feels like the equivalent of a piece of music resolving on a satisfying chord, the culmination of everything the year has been building towards.

I am on holiday here with my girlfriend and some of her family and friends, staying above the village of Hartsop, close to Brothers Water. This small, shallow lake is home to rare species such as the schelly (Coregonus stigmaticus) – a relic whitefish endemic to just four Lake District lakes – and a community of bottom-rooted plant species, some of which brush slimily against my legs as I go in for a quick dip. My companions are fazed by the reeds, but I wave away their concerns with the haughty confidence of a seasoned wild swimmer.
