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.”

  • Rising demand for exotic pets is pushing many gibbon species to extinction, with their strong family bonds making them especially vulnerable to the brutal trade

    It is a cool morning in Thailand’s hilly north, and a wildlife officer sits on the veranda of Omkoi wildlife sanctuary’s office. On her lap is a wide-eyed infant primate dressed in baby clothes. Not unlike a human baby, he kicks and waves excitedly. Most of his dark skin is covered in dense white fur, except for his face and the palms of his hands.

    “We call him Chokdee,” the officer says. “It means ‘good luck’.”

  • Caistor St Edmund, Norfolk: Firebugs congregate in large numbers to feast and mate – and this is the first time we’ve known their revelry on the farm

    At this time of year the farm is a popular spot, with people strolling, horse riding or picnicking from dawn till dusk. One of the unexpected joys of opening up public access is the extra pairs of eyes. A broken fence or fallen tree is noticed almost immediately; an otter is spotted slipping into a stream at first light. Recently, Laura, a regular dog walker and keen photographer, shared something new.

    Congregating on the sunny side of an old lime tree is a colony of firebugs. There are 50 or so, clustered together, like flames flickering up the trunk. Each is nearly a centimetre long, with ember-bright red backs marked by bold, symmetrical black shapes. These aggregations, typically on lime or mallow, are for mating and feeding. A firebug eats seeds, aphids or even its dead relatives, sucking out moisture with its proboscis.

  • Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying

    The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said.

    The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).

  • Despite the ban on disposables, waste professionals say the mountain of discarded devices is a £1bn-a-year issue

    It is 2pm and Ana, 47, has just started the afternoon shift at the Suez recycling plant near Birmingham city centre, standing beneath a sign reading “Non-ferrous sorting station” with a bucket of vapes in front of her. Sorting and dismantling them is part of her job as a site operative.

    Recycling them is not simple. Each bucket holds between 40 and 50 devices, and over the course of a shift, she gets through about half a bucket. Using a hammer, she has to smash each vape open, pry out the batteries and separate each component into a different container.

  • Climate and transport organisations warn ministers not to ‘sleepwalk into crisis’ amid Iran war oil and gas shortages

    Private jets should be banned and the speed limit on UK motorways reduced to 60mph as part of a pre-emptive effort to ease the looming fuel supply crisis, according to leading climate and transport organisations.

    The group – including Greenpeace and Transport and Environment – are calling on ministers not to “sleepwalk into a crisis” that could lead to severe shortages of jet fuel and spiralling petrol prices at the pump in the coming months.

  • Like many informal settlements, communities that have sprung up on the edges of Ayacucho in the Andes are on the frontline of extreme weather events

    In December 2009, a late‑afternoon storm unleashed torrential rain over Ayacucho, in Peru, hitting poor hillside neighbourhoods hard. The deluge overwhelmed drainage systems, turning streams into lethal flows of mud, stones and debris that flooded houses and streets and trapped drivers at a busy junction.

    Ten people died, 18 were injured, and 530 houses were destroyed or damaged, according to a government inquest. “It was a disaster,” recalls Edgar Castro, a leader in Ayacucho’s largest informal neighbourhood, Mollepata.

  • With Israel blocking imports of building materials, those rebuilding in Gaza are recycling ruins to make new homes

    It is difficult to see through the dust inside the cramped, low-roofed tent on the eastern edge of Khan Younis. Ibrahim al-Aloul works alongside four others, with a piece of fabric tied over his mouth and nose as his only shield against the toxic grey powder as he sifts and grinds.

    Outside, a skinny donkey waits with a cart to carry the finished product to the next tent along, where it will be mixed with gypsum, calcium and binding agents before being bagged in flour sacks and sold.

  • When Sousan Samadani saw a video about soil degradation, she suddenly knew she would commit everything she had to the cause. Soon she was travelling thousands of miles to raise awareness, skydiving, hitchhiking and cycling

    Sousan Samadani was watching videos on YouTube one day when she came across a post about how the world’s soil was degrading so rapidly that it was in danger of extinction.

    The video – posted by the Save Soil movement – “was like a shock for me”, Samadani says. “I thought: ‘How is it possible that the soil that gives us food is dying?’”
