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

Charaxes jasius ~ Two-Tailed Pasha ~ vještica

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!

Two-tailed pasha

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.”

  • Moreangels Mbizah has blazed a trail in Zimbabwe as the first black African woman to found a conservation organisation in the country

    The turning point for Moreangels Mbizah came in 2014. The conservation biologist was in Hwange national park in Zimbabwe, scanning the savannah to monitor the movements of lions for her zoology PhD research.

    The GPS signal told her something was wrong. One of the lions had strayed into a nearby village, putting itself and the local community at risk. Mbizah and her team took off to try to herd it back into its habitat.

  • Nearly 60 countries back voluntary roadmaps to wean world off coal, oil and gas, at conference prompted by frustration with UN climate summits

    Governments have been asked to develop national “roadmaps” setting out how they will end the production and use of fossil fuels, after a landmark climate meeting involving nearly 60 countries.

    The voluntary plans will form the bedrock of a new initiative to wean the world off coal, oil and gas, the focus of two days of intensive talks in Colombia this week.

  • With record temperatures bringing increased numbers of seals and dolphins, scientists say large predators could return to UK waters

    Last year water temperatures in the North Sea reached record levels, with average surface temperatures a balmy 11.6C, the warmest since measurements started in 1969. And as waters continue to warm, a new study suggests great white sharks could start prowling British waters.

    Olivier Lambert, from the Royal Belgian Institute of Natural Sciences, and colleagues studied whale fossils recovered from North Sea sediments dated to around 5m years ago. North Sea waters were warmer at this time and were home to several species of whale and shark. Fossilised tooth fragments embedded in the whale skulls revealed that sharks had feasted on them.

  • Elusive nightingale ‘doing well’ at Northward Hill, Kent, but experts cite concerns around loss of habitat

    The dawn chorus at RSPB Northward Hill in Kent is a riot of sound: the melodic robin, the two-tone cuckoo, the whitethroat’s scratchy warble. Even the garbling geese and mooing cows from the neighbouring Thames marshes add to the symphony.

    But in late April one energetic singer hogs the limelight. For a few weeks after arriving from West Africa, the nightingale spends the night – and early morning – in complex song. As it searches for a mate and marks its territory, its song is at times as sweet and tuneful as a soul singer, at others as frantic as a car alarm.

  • The bizarre vertical flight pattern has long puzzled experts but new research reveals why it may play a crucial role in the insect’s survival

    On a spring evening along the banks of the River Thames, thousands of mayflies can be seen engaging in what may be one of the world’s oldest dances. In the fading light, the males make a steep vertical climb, flip over and float back to Earth – wings and tail outstretched in a skydiving posture so as to drop slowly through the sky.

    Mayflies are among the world’s oldest winged insects, emerging roughly 300m years ago – long before dinosaurs walked the Earth. Even the Mesopotamian poem the Epic of Gilgamesh, one of the oldest pieces of literature, makes reference to the short-lived mayfly. Over the epochs, the insect’s basic design has changed very little compared with the fossils of their ancestors.

  • Abernethy Forest, Scotland: On glorious mornings like this, with the woods ringing with sound and light, I’m glad there is extra protection from wildfires

    In the pinewoods, the colours are slowly shifting, the birches to their spring green and the larch roses blossoming pink. The pair of pied wagtails have returned to our neighbour’s shed and the peewits are back on the marshes, though fewer in number (and there are two pairs of crows that maraud their territory).

    The siskins have returned in numbers, huge skeins of geese have been flying north, and the swallows and housemartins are back earlier than usual, though they are still just passing through – “ours” are not yet here.

  • A KCL study has found that exposure during the first trimester of pregnancy delayed speech development

    Babies exposed to higher levels of air pollution in the early stages of pregnancy take longer to learn to speak than those exposed to lower levels in the womb, new research suggests.

    A study by researchers from King’s College London found exposure to nitrogen dioxide and fine and ultra-fine particulate matter during the first trimester of pregnancy delayed speech development at 18 months.

  • A Canadian social enterprise hopes to help solve the urgent need for retrofits and shortage of skilled workers

    John Mava was looking for work when a construction project started behind his house. When he visited the site and saw how different construction was in Canada compared with his native Nigeria, his interest was piqued.

    “I said it would be great for me to have knowledge about this,” said Mava, who learned that in Canada, construction uses timber rather than bricks and has a focus on the environment.

  • Researchers found the loss of just a few eggs to opportunistic predators could greatly increase the songbird’s risk of extinction within 20 years

    Captured on one of Bianca McBryde’s tree-mounted cameras, the brush-tailed possum crawls into the frame, lowers its head into the nest and bites into the egg.

    The snack was a shop-bought quail’s egg and the nest was artificial – a crafty construction made of half a tennis ball, some brown paint and fibres from the husks of coconuts.

  • Authorities are yet to decide how they will move the body of the massive creature, which is attracting humans, eagles – and plenty of sharks

    Thin strips of flesh hang down like rotten tinsel, swaying in the wind. Glistening fluid trickles on to the stone where insects buzz. On the windward side, the odour is masked by the salty air. But step downwind, and you enter a sickly, sour-sweet blend of garbage and rotting fish. A passing couple pull their T-shirts tight over their noses.

    On a rock shelf at the southern end of Era beach, the estimated 25-tonne body of a sperm whale rests like a melted candle. Looking down at the rock pools, floating chunks of white fat bob in the water.
