Winchester school children help launch Big Butterfly Count 2025

People are being urged to count the butteries and moths they see to help experts assess the "butterfly emergency".Conservationists and students from St Swithun's School in Winchester gathered on Magdalen Hill Down in Hampshire to mark the start of the 24-day Big Butterfly Count Saville from Butterfly Conservation, which runs the project, said the health of butterfly populations was a "really good indicator" of how well other wildlife was doing."If you don't see butterflies then you should be worried and we should be taking action to improve the natural world," he said. Last year's butterfly count yielded concerning results, with low numbers prompting Butterfly Conversation to declare an "emergency". The event runs from 18 July to 10 are encouraged to choose a spot and count the butterflies and moths they see there for 15 minutes per day, logging it on the website or via the app."Then our data scientists will get those numbers and crunch the numbers," said Dr Dan Hoare from Butterfly Conservation."It's a way of tracking the state of nature every year, reacting to the kind of wild weather rollercoaster that we have now."There are hopes that, with the warm weather, this year's count could be more positive."It's looking really promising," said Dr Hoare. And it is not just about butterflies, according to site manager Fiona Scully."Moths are often underrated but they're still very important for pollination, and there's so many more moths - there's 2,500 species of moth, which vastly outweighs the number of butterflies," she said."They're doing a very important job of pollination, and they're also incredibly important in our food chain... they're really needed to support other animals."

Pollinating insect count for City of London

Bees, butterflies and moths are being counted across the City of London on Thursday to document the state of insect Annual Pollinator Count aims to track pollinator populations in a bid to learn more about the variety of species in the square mile, and their role in the organised by charity Pollinating London Together, will take place in Christchurch Greyfriars Church Garden, St Paul's Festival Garden and Inner Temple can take part in the count by downloading the FIT app to register which pollinators they spot in any green space in the square mile.

Country diary: Hunting for a sooty anomaly among the razzle-dazzle

As we swelter through the meadow, our heat-loving companions bask on knapweed and field scabious, stirring every few seconds to chase off rivals or woo potential mates. The dark green fritillaries and feisty marbled whites command our attention with their dramatic and intricate wing markings, while small heaths, skippers, ringlets and meadow browns provide the butterfly chorus. Distracted by the razzle-dazzle, I've forgotten that we're hunting for a sooty anomaly in the summer meadow. With its penchant for flying in bright sunshine, the chimney sweeper could be mistaken for a butterfly, but is, in fact, a day-flying moth. It's one of about 130 macro-moths in the UK that take to the wing during daylight hours, more than twice the number of butterfly species. Many exhibit vivid colouration or striking patterns, such as the cinnabar, emperor, scarlet tiger or hornet moths. In contrast, the chimney sweeper has no patterning on its black body save for a white margin on the forewings, and it keeps a low profile, alighting on grass stems or making short flights around the white umbel flowers of pignut, its larval food plant. Today, its profile is so low that we fail to see it at all. Instead, I notice a papery sail high on a grass stem by the path. Inside the cocoon is a pupa in which a lemon and black caterpillar is metamorphosing into another day-flying moth: a six-spot burnet. Once we've seen the first sail, every other grass stem in the meadow seems to hoist its own cocoon and a fleet of burnets is launched. Some stems host caterpillars waiting to pupate, while others display empty vessels where parasitic flies or wasps have consumed the larvae, then vacated through the cocoon wall. A quick calculation suggests that if we're looking at an acre and a half of meadow with eight or nine cocoons per square metre, there might be as many as 50,000 burnet moths coalescing in front of us. After a fortnight or so in their silken cases, they'll emerge with one purpose – the continuation of their thriving colony – a yearly commemoration of the forgotten concept of abundance.
