Christmas Butterflies

Red Admiral

The Red Admiral (Vanessa atalanta) is often the last butterfly to be seen flying in the UK and parts of northern Europe. This colourful insect can be seen in December in mild winters and Butterfly Conservation reported on their Facebook page that the organisation had received recent reports of butterflies being sighted and they shared a photo of a Red Admiral.

The Red Admiral has Christmas colours too because its wings are boldly market with red and white on dark brown and black. This pretty butterfly, which is also found in Asia and North America, is a migrant to the UK but it can hibernate so is a resident butterfly as well. It is one of the last species to be seen in the late autumn, and can be seen feeding on ivy blossom and on windfall fruit. It also flies on sunny and mild winter days.

The Red Admiral's caterpillars feed on Stinging Nettle (Urtica dioica).

The Painted Lady (Vanessa cardui) is not a butterfly you will see in the UK at Christmas, but here in Portugal it is still about in December and I saw one the other day in a sunny spell in what was otherwise a cold and foggy day. It was a very pleasant surprise and got me thinking about this butterfly that is a very successful species unlike so many butterflies that are rapidly declining in numbers.

The Painted Lady is another migrant to the UK and Northern Europe.  It comes from North Africa and the Canary Islands but its northerly migrations have taken it as far as Iceland where it is the only butterfly species that has been reported. The Painted Lady has been found in most parts of the world and is almost global in its distribution.

Unfortunately, unlike the Red Admiral, the Painted Lady is unable to survive British winters in any stage of its lifecycle.  It is a truly remarkable butterfly though because scientists have discovered that it uses the jet stream to carry it on its migrations. The Painted Lady leaves Britain in the autumn to fly south and it does this by being carried in the fast-moving air of the jet stream.  

Besides the Painted Lady's extraordinary migrations, the species does so well because its caterpillar will feed on a lot of different food-plants, including species of thistle (Carduus). Sunflower (Helianthus),  Mallow (Malva) and Burdock (Arctium). Like the larvae of the Red Admiral, the caterpillars of the Painted Lady will also eat nettles. Caterpillars of the Painted Lady are often sold by butterfly supply companies such as Worldwide Butterflies.  They are ideal for schools where children can study the insects and watch them transform from caterpillars into chrysalises into adult butterflies. 

Butterfly World Project

Many butterflies are in danger of becoming extinct in the modern world due to habitat loss, pesticides, herbicides, disease and Climate Change, so they need all the help we can give them. Butterfly World Project in St Albans was set up to help butterfly conservation but has been forced to announce its closure.  Please help by signing the petitions to stop this happening.  I have written all about it in a previous blog here

Where does all the plastic go?

Where does all the plastic go? 
Into the sea, into the sea.
How does it get there, who threw it away?
Was it you or was it me?

Plastic houseplants, why not real plants?
I saw the fake ones at the store,
Shoppers must want them, people must buy them;
I don't want to see any more.



It's not just hunting that'll kill the last whale,
Plastic will do it and it's a very sad tale.
What about the albatrosses?
They are dying out too,
They keep on fishing in the ocean's plastic stew.
These birds mate for life, only to watch their babies die,
From the plastic trash they feed them,
But they cannot understand why.

The plastic bag I bought, it very quickly broke,
If it ever gets burned there'll be poisonous smoke.

Plastic kills the turtles,
Plastic's eaten by the fish,
It is in the food chain,
And in the dinner on your dish.

Into the sea, into the sea.
How does it get there, who threw it away?
Was it you or was it me?

Paris’s Shortcomings: We Need Conservation, Not Conversation says David de Rothschild

An excellent article entitled Paris’s Shortcomings: We Need Conservation, Not Conversation by author and explorer David de Rothschild, has been published by National Geographic, in which he talks about the serious shortcomings of the recent Paris conference on Climate Change. He points out the truly alarming rate at which our forests are being destroyed and species of plant and animal are becoming extinct daily. Nowhere near enough is being done to halt the ongoing destruction and nowhere near enough binding agreements have been made. It has been a lot more talk but not a lot of action!

David says: "...most experts agree that we are losing upwards of 80,000 acres of tropical rain forest every day. Factor in a statistic that says conservatively we’re loosing anywhere between 135-200 plant, animal, and insect species every day, and you realize that between now and 2020, we stand to lose 1,460,000,000 acres of tropical forest and 273,750 species!"

I hear what he is saying loud and clear!  It really saddens me to know how many species we are losing all the time.  You do not have to know much about nature to see that once common birds and butterflies are vanishing, as are honeybees, which we are told is due to Colony Collapse Disorder.

In the UK, most butterfly species are in rapid decline, as are formerly common birds like the House Sparrow.

Every time I talk to my elderly father, who lives in Cardiff, he complains about how he no longer sees birds like blackbirds, starlings, great tits, robins, green finches, wrens and hedge sparrows, all of which used to be regular visitors to his back garden.  When I have visited him I have seen for myself that these birds have gone.  So too have the swifts. These birds used to nest on houses in the street my father lives in. In May you would hear and see them all the way along the road but no longer is this the case.

I have recently blogged about the shocking decline in hedgehogs in the UK. They are now down to less than one million.  These animals used to be a common sight in our gardens at night.

So I know what David de Rothschild is talking about is true. We are losing species daily and we cannot bring them back.  Extinction cannot be undone.  Extinct means gone for good!

I thoroughly recommend De Rothschild's book The Live Earth Global Warming Survival Handbook: 77 Essential Skills to Stop Climate Change, and his Plastiki Across the Pacific on Plastic: An Adventure to Save Our Oceans.  This second book is about the voyage De Rothschild made across the ocean. He saw for himself that the fishes and marine life have vanished. Pollution by plastic and overfishing are destroying marine life daily and little is being done to stop this.  Too little too late is being done to stop the environmental destruction happening worldwide!
