Beware: caterpillars processing!

The caterpillars of the pine processionary moth (thaumetopoea pityocampa) come out any time between February and April each year.

In 2022 there have been large numbers of the fine woolly nests of these caterpillars all around Hvar. They are exquisitely delicately formed, an example of Nature's perfection. Female moths lay their eggs on the branches of pine trees, The caterpillars form their nests from silken threads, which keep them warm and protected through the winter. They feed from the branch on which the nest has been spun. When the caterpillars leave, the nest disappears, leaving no trace of itself.

The journey of the caterpillars out of their nests in search of the ideal place to pupate is fascinating. They form long columns, nose to tail, following a leader in apparently random exploration over a surprisingly wide area. If they meet another column going in a different direction, one column splits to allow the other through, then reforms and continues on its way. When the leader finds the right place, the caterpillars burrow underground to pupate, emerging as moths from the early summer onwards.

Left alone, the caterpillars do no harm. However, they are heavily armed! When touched, they cause an extremely uncomfortable allergic reaction. There is a specific danger for dogs. Treading on the caterpillars or coming into any contact with them causes a severe inflammatory reaction. If the dog licks the affected area, its tongue can be badly damaged, which in the worst of cases can be fatal.

It's been reported that the caterpillars have started processing in early February. Dog owners beware! Don't go walking in the pine woods until the nests are empty. If your dog comes into contact with the caterpillars, consult the vet as quickly as possible.

  • Scientists say record-breaking heat is a reminder of how climate crisis is affecting lives

    The fierce heat sweeping across Europe over the bank holiday weekend has beaten the UK’s all-time temperature record for May, with scorching highs of close to 35C.

    A temperature of 33.5C was recorded at Heathrow airport on Monday lunchtime, according to provisional data from the Met Office, beating the previous May record that was set in 1922 and reached again in 1944. Later in the afternoon a temperature of 34.8C was recorded at London’s Kew Gardens.

  • Charing, Challock and Molash worst affected, as South East Water says ‘technical failure at pumping station’ to blame

    Hundreds of homes in Kent and Sussex have been left without water by a company that MPs recently accused of incompetence.

    South East Water said the hot weather and extra demand for water meant it was having to pump more drinking water than usual to higher ground.

  • Rain overwhelms sewer system in parts of US city, while temperatures in France break May record

    New York City saw flash flooding on Wednesday, as large parts of Brooklyn and Queens received about 2in (50mm) of rainfall in as little as 20 minutes. Officials said the deluge caused water to flow into the sewer system at a rate of up to 6in an hour, quickly overwhelming an aged network that was designed to accommodate just 1.75in an hour.

    Residents and commuters found themselves wading knee-deep through flood water that flowed with dangerous speed in places. One video showed a woman alighting from a bus losing her footing and being dragged along by the torrent of water. Several major roads were blocked, including the Long Island Expressway, and subway services were disrupted as water spilled into stations. Large amounts of mud and other debris was left behind; videos showed bags of rubbish being swept down streets along with loose litter.

  • Most people have joyful memories of playing outside as children – and now wildlife charities are urging people to ‘rewild their inner child’

    Climbing trees, squelching in mud, paddling in ponds or making dens in the woods – people’s memories of playing outside as children are often vivid and, a new poll has found, overwhelmingly positive, even those who remember falling in cowpats.

    Almost 90% of UK adults had rosy memories of the excitement and the feeling of freedom that outdoor play had brought them, the survey found. However, almost half of adults now spend less than three hours a week in natural settings such as gardens, parks, fields or woods, according to the survey. For one in 10 it is less than one hour.

  • Charter to be adopted along river’s entire catchment from Cambrian mountains to Chepstow and Bristol Channel

    The entire catchment of the River Wye has been formally recognised as a living ecosystem with intrinsic rights in a charter, a UK first that campaigners hope will help save the highly polluted river.

    The charter was celebrated at a community event at the Hay-on-Wye literary festival on Sunday. It includes the right to flow, to biodiversity, to be free from pollution, to be supported by a healthy catchment, to regenerate, and the right to be represented, described as a “significant step” towards protecting and restoring one of the UK’s most beloved rivers.

  • Definition of green facilities made in 2022, before release of ChatGPT, says Action to Protect Rural Scotland

    A Scottish government policy designed to encourage datacentres to build in Scotland could lead to a massive volume of carbon emissions being ignored, according to an analysis by a Scottish charity.

    “Green datacentres” are at the heart of Scotland’s ambitions to develop economically. Enshrined in national policy, they are part of a larger, UK-wide effort to attract big AI investment to Scotland.

  • Talybont, Ceredigion: On a crisp, post-rain morning, I take a walk among bright hawthorn blossom and the glittering pools of Cors Fochno

    On the edge of Talybont, the small cemetery, kempt and cared for, overlooks the coast and the wild brown swathe of Cors Fochno (Borth Bog). A burial ground is perhaps an odd place to begin a walk, but, as a friend remarked, it’s infinitely better than ending one there.

    The early rain has cleared so the air is crisp and the colours deep. In the foreground, grassland fields slope away towards the wild expanse of the bog, bounded by wooded hedgerows bright with hawthorn blossom. The first cut of silage has been secured, baled and removed, and a few cattle are grazing the aftermath with interest while red kites traverse overhead. The surface of the bog, marked here and there by glittering open pools, shimmers slightly in the heat of the day. Across the Afon Dyfi, the steep-faced sand dunes of Aberdyfi are visible before the eye is drawn further off to the line of hills that defines the Llŷn peninsula.

  • Like so many Britons, I usually consult a weather app before venturing out of the house – and often cancel plans if I don’t like what I see. Here’s what happened when I went cold turkey for a week

    When I heard on the radio that more than half of British people would consider cancelling an outing if they saw a 40% chance of rain all day on their weather app, I felt seen. I, too, am a slave to my app. Not that I would ever make a decision based on one whole-day percentage. I pore over three-hourly breakdowns for chances of rain versus minutes of sunshine. If rain is on the cards, I check the probable millimetres. Less than one? I may well throw caution to the wind. Speaking of which, wind speed and direction must also be considered, along with overall and “feels like” temperatures. For the cherry on top, I’ll compare notes with a loved one’s app if they use a different one, quietly mistrusting theirs, and simmering in silent rage if theirs wins.

    I’ll admit, though, that my compulsion to check my app (I long ago chose WeatherPro, which I knew nothing about, but liked its layout and name) is borderline neurotic; I fret over probabilities and outfit appropriateness, when I could simply step outside for real-time hyper-local accuracy. I can lose procrastinatory hours consulting long-range forecasts, or checking the weather in Melbourne (where my sister lives) and holiday destinations I have no immediate plans to visit.

  • The state saw 33 tornadoes last year and severe flooding as researchers say links to climate change are undeniable

    The tornado hit west Ann Arbor at 1.45am on 15 April, passing through Veterans Memorial park, where it knocked several mature oak trees and ripped up baseball field fences before setting its sights on a local ice rink.

    “It came up through the parking lot and, in that time, the pressure differential between the tornado and the air inside the rink collapsed the wall,” said Scott Spooner, a manager at Ann Arbor Parks and Recreation.
