Hvar's Butterflies

Marion Podolski casts her expert artistic eye over Hvar's butterflies.

Butterflies always seem so fragile, so transient. So it came as quite the surprise when I read that (a) there are butterfly fossils dating back around 56 million years, and (b) the Painted Lady appears to hold the record for the longest return migration, from Africa to the Arctic circle and back!

Painted lady

This photograph was taken at Vorh on Hvar, altitude around 500 metres. European ivy is known for having flowers high in nectar, and was swarming with butterflies and bees in September. The Painted lady migrates from North Africa and the Mediterranean northwards in the springtime, and southwards in the autumn. The 9,000 mile round trip between tropical Africa and the Arctic circle may take as many as 6 generations! Was this butterfly on a refuelling stop for its Autumn migration?

This summer I’ve been more aware of butterflies on Hvar, possibly due to my recent interest in wildflowers. It’s a good sign, as flowers and butterflies mean a healthy ecosystem. Though sometimes they were nowhere near any flowers!

Red admiral

As I was sitting on the Soline beach near Vrboska, painting with my art group, this visitor was very interested in my paintbox! Luckily I had my phone to hand, and managed to capture the moment! And as I didn’t really feel that paints were proper nourishment, being toxic and all, I closed up the box, so it decided to try some wine instead!

While some (adult) butterflies live only for a few days, other species survive for almost a full year. Those living longer can feed on nectar from flowers, and they are in fact important pollinators for some kinds of plants. Although they can’t carry as much pollen as bees, they are able to take it over longer distances. They’ll also sip water (and wine!), are sometimes  attracted to dung, rotting fruit, or the salt in human sweat for other essential minerals and nutrients. Their “taste” receptors are apparently located on their feet, so they can determine whether a leaf is suitable for laying eggs on (ie the caterpillar kids can eat it!)

I spotted this Red admiral near the peak of Sv Nikola, up in the high country (628 metres). Good view of the underside of the wing. Red admirals also migrate, spending summer in northern Europe, and winter near the Mediterranean.

In Croatian, a butterfly is called a leptir, for once easy to remember as it’s clearly related to lepidoptera (from the ancient Greek  lepís=scale + pterón=wing). It’s less certain why the English saw any association with butter, though the name has been around for some time in old Dutch and German. Were there only yellow butterflies in northern Europe, I wonder?

Two-tailed pasha also going for my wine

Another butterfly that was keen to share our wine was this Two-tailed Pasha with exceptional taste at restaurant Laganini on Palmižana! It did, in fact, take a dive headfirst into my glass and had to be rescued at the expense of the wine!

A fine butterfly, and a great poser with his proboscis stuck into a drop of lemon sorbet (with vodka and prosecco) for a good long drink! Two-tailed pashas produce two generations in a season, flying May/June and August/October. Clearly, they also like a drink!

The beautiful colour of butterfly wings is due to the scales. While the dark blacks and browns are melanin pigments, and yellows come from uric acid and flavones, the other bright blues, greens, reds and iridescence are all caused by the structure of the scales and hairs.

Cardinal

Meanwhile, back at the popular ivy flowers, was this lovely Cardinal which is a fairly common butterfly around southern Europe from April to September. Sadly the photograph doesn’t quite do justice to the shimmer of that pale green colour. Very pretty in real life!

The second Cardinal was spotted in a garden in Stari Grad. Good view of the antennae, and the proboscis stuck into the flower. It looks to have only 4 legs, but that’s apparently normal for some types of butterflies, the front two legs are much reduced.

Wall brown

Lasiommata megera ~ Wall Brown ~ mali pjegavac

Hmmm, the field notes say the Wall brown is very alert and difficult to approach for taking photos – well, that’s certainly true! This guy was spotted beside the path on the way up to Sv Nikola, and this is the best photograph I could manage!

A recent (2011-13) study of butterflies on Hvar recorded 49 species, some of which are very rare within Croatia. All in all, 57 species have been recorded on Hvar, giving it 4th place among the islands for butterfly diversity. I have a long way to go to spot all those!

“Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.”

  • Analysis reveals big regional disparities as critics say Labour’s proposed levy could slow uptake of EVs

    Drivers in the south-west of England would pay nearly four times as much as those in London as a result of Labour’s mileage-based tax on electric cars, according to analysis of official data.

    The 3p-a-mile road charge, announced in the autumn budget and due to take effect in 2028, is expected to raise £1.1bn a year, partly offsetting the loss of fuel duty revenues as drivers switch from petrol to electric vehicles.

  • JD Vance is seeking to create a ‘trading bloc’ as shortages and climate crises mean a kaleidoscope of rare earths are increasingly jealously guarded

    The announcement by the US vice-president, JD Vance, that the country is seeking to create a new critical minerals “trading bloc” is a final, exotic, nail in the coffin of the old global trading system. The era of mass abundance, as supplied by unfettered free trade and global markets – “neoliberalism” – is over. We live in a new world of strategic competition between states over scarce but essential resources, with shocks to supplies from human activity and natural disasters an ever-present risk.

    This means recalibrating how we think about our economy: the new economic fundamentals today are resource constraints and climate and nature crises, and these, rather than human activity, will increasingly shape the world we inhabit. Flows of finance and stocks of wealth will matter less than stocks and flows of real material resources.

  • The fight for Hope Moor is set to be repeated across the UK as the government aims to hit its renewable energy targets

    Instead of a slingshot, the Davids are brandishing a sculpture and a coffee table book. Their Goliaths are a Norwegian energy company and a UK energy secretary with renewable targets to meet.

    A fierce battle has begun over one of England’s tallest windfarms, proposed for deep peat moorland overlooking the Yorkshire Dales national park, in what residents say will mark the irrevocable industrialisation of their rural landscape.

  • Low pressure system funnels rain over already saturated areas, compounding risk of further flooding

    A deep area of low pressure to the south-east of New Zealand’s North Island swept into the region on Sunday, bringing heavy rain, gale-force winds and dangerous coastal swells that lashed exposed shorelines. The storm triggered power outages, forced evacuations and damaged infrastructure, with further impacts likely on Monday as the system lingers for a time, before tracking southwards later.

    Its arrival came after days of widespread flooding in the Ōtorohanga district, where a man was found dead after his vehicle became submerged in flood waters. Some areas recorded more than 100mm of rain in 24 hours on Thursday, with Gisborne, Hawke’s Bay and the Bay of Plenty bearing the brunt of the deluge. The Tararua district and Wairarapa have also been experiencing heavy rain and strong winds from the storm, with 24-hour rainfall totals reaching more than 100mm locally, and wind speeds of about 80mph (130km/h) along coastal parts.

  • Frome, Somerset: As the large raptor squirms and uses its wings to try to balance on a precarious perch, I find my own arms lifting in solidarity

    Six, seven, eight, nine long‑tailed tits are on a foraging flit through hawthorn bushes, and the straggler drops obligingly on to a berry‑stacked twig before my eyes. Its tail works like the hand of a clock as the clinging bird jiggle‑jumps through a full 360-degree rotation, beak pecking for who knows what. The twig is unmoved by such exertions, for the bird weighs the equivalent of seven paperclips. What must it be like to inhabit the insubstantial ghost‑world of a long‑tailed tit, where you can leap and land all you like with no discernible impact?

    Ahead and above, a bird 100 times its weight is weightless in the sky. The soaring buzzard masters gravity with its “fingertips” – the deeply separated primary feather tips on the wings. I cannot see the little flicks and tilts that enable it to descend in controlled steps; drop and hold, drop and hold.

  • Images confirm xAI is continuing to defy EPA regulations in Mississippi to power its flagship datacenters

    Elon Musk’s artificial intelligence company is continuing to fuel its datacenters with unpermitted gas turbines, an investigation by the Floodlight newsroom shows. Thermal footage captured by Floodlight via drone shows xAI is still burning gas at a facility in Southaven, Mississippi, despite a recent Environmental Protection Agency (EPA) ruling reiterating that doing so requires a state permit in advance.

    State regulators in Mississippi maintain that since the turbines are parked on tractor trailers, they don’t require permits. However, the EPA has long maintained that such pollution sources require permits under the Clean Air Act.

  • Project in Ceredigion aims to help country catch up with large-scale nature recovery projects elsewhere in UK

    A Welsh charity has bought more than 480 hectares (1,195 acres) in Ceredigion to establish Cymru’s “flagship” rewilding project, helping the country catch up with large-scale nature recovery projects under way elsewhere in the UK.

    Tir Natur (Nature’s Land), founded in 2022, announced it had acquired the site at Cwm Doethie in Elenydd, or the Cambrian mountains, after a fundraising drive launched last year raised 50% of the £2.2m purchase price. A philanthropic bridging loan enabled the sale.

  • The charger firm claimed the site operated 24 hours a day, but the parking operator had different ideas

    I charged my electric car at the 24-hour Mer EVcharging station in my local B&Q car park.

    I then received a £100 parking charge notice (PCN) from the car park operator, Ocean Parking. It said no parking is allowed on the site between 9pm and6am.

  • Some districts are adding programs in clean energy and sustainability, while one state is infusing environmental lessons into culinary education and construction

    On one end of the classroom, high school juniors examined little green sprouts – future baby carrots, sprigs of romaine lettuce – poking out of the soil of a drip irrigation system they built a few weeks prior.

    On the opposite end of the room, a model of a hydropower plant showed students how the movement of water can stimulate electrical currents. In this class in South Carolina’s Greenville county school district, students primarily learn about one topic: renewable energy.

  • Wild gardening is about shedding obsessions with tidiness, embracing a looser aesthetic and providing a home for ‘the most important creatures on the planet’

    On a wintry January day in Manchester, I crossed University Green, navigating a paved path behind our hotel through lush patches of lawn. It was the start of the inaugural “Wilding Gardens” conference. For two days, scientists and practitioners were gathering to discuss new ways to think about gardens and nature, about what nature needs to thrive, and the untapped potential of gardens – if we step back and allow ecological processes to unfold – to help counter climate change and biodiversity loss.

    Clumps of snowdrop flowers poked through the unmown grass and a grey squirrel streaked across it, from one bare-branched tree to another. Probably common alders, going by the University of Manchester Tree Trail. The world’s first industrial city seemed an apt venue for a talkfest on the urgency of rewilding suburban gardens to help save the planet from precisely what drew Marx and Engels there to study, 180 years ago: the impacts of industrialisation.
