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.”

    It may seem small among the decisions people have to make as they face the end of their life, but what happens to their bodies can make a significant difference to the final cost inflicted on the environment.

    In many Western countries, cremation is the most common method of deathcare – chosen by about three-quarters of Australians – but it’s arguably the most environmentally damaging.

  • Experts worked in ocean midwater off Brazil at near-record speeds thanks to cutting-edge tech

    A marine biology expedition in international waters off the coast of Brazil has discovered 31 new species in just two weeks.

    The researchers believe the speed at which the species were found and identified may be a record, in part because of the cutting-edge technology designed and built by the science and engineering team. For the first time on board a ship, the researchers were able to observe the living 3D cellular structure of microbial life thanks to a technological breakthrough nicknamed the Squid.

  • Edinburgh:As we are visually impaired, we love to appreciate the sounds and smell of the woodland. This time it had been raining, so we could smell the wet ground

    Our school, the Royal Blind school, Sight Scotland, is across the road from the Astley Ainslie hospital. The hospital gardens are open to the public and have over 2,000 trees, and sometimes we go to there for outdoor learning lessons with Margon, who helps us learn about the outdoors.

    Recently we went to a wooded area to make a den for shelter. We could see lots of green everywhere. It had been raining but we could feel the warm sun and smell the wet ground, which was spongy and soft under our feet. It had been windy and there were twigs and leaves on the ground. We found a tree with textured bark that felt like veins. Margon told us that the bits we could feel were old ivy vines. We could hear lots of birds and feel the breeze and hear it rustling the leaves.

  • Emerging research suggests datacentres create a heat island effect, pushing up temperatures in the immediate vicinity by as much as 9C

    The community living next to the largest datacentre park in Europe say the scorching summer heat has grown unbearable.

    On days like Wednesday, said Nabeel Nawaz, the store manager of a Chaiiwala franchise in the centre of Slough, the heat is like something “pinching your body and burning your skin”.

  • As temperatures soar across Europe, cities are struggling to adapt, further exacerbating socioeconomic divisions

    The heatwave afflicting western Europe is the worst ever, with the combination of heat and humidity fuelled by the climate crisis making scores of cities feel unliveable. While for some the adverse impacts amount to disturbed sleep and sticky days in the home office, low-income families are often worse affected by cities’ lack of adequate adaptation measures, with women at the sharp end.

    “[It] throws a grenade into every vulnerability you already have,” says Asad Rehman, chief executive of Friends of the Earth, pointing out that vulnerable or marginalised groups often bear the brunt of climate crisis-based hardship globally.

  • Economist Prof Mariana Mazzucato says governments must ‘get back their mojo’ and believe they can change the world

    Good governments have a vision. They know what they want to achieve, can articulate why, and work out in public how to get there. They don’t just spout slogans about economic growth – because growth is meaningless unless we know what it is for. They understand that there is no trade-off between solving social problems and boosting the economy, and aim to do both, while avoiding rigid fiscal rules that defeat their own purpose by strangling public investment.

    If this sounds like a critique of what went wrong with Keir Starmer’s government, it is also a lot more. Mariana Mazzucato, a professor in the economics of innovation and public value at University College London, is a world-renowned economist, adviser to governments, chair of international commissions, prolific author, and PhD supervisor to at least one poet. She was the thinker who inspired Starmer to fashion his political project around five key “missions”, now largely forgotten in the mire of scandals, U-turns and infighting that beset his premiership.
