Early Autumn

Autumn began properly last Monday, 23 September, with the Autumn Equinox. This year there is a superabundance of berries of all kinds – most spectacularly those roaring red ones of the Rowan or Mountain Ash tree, and blackberries, the fruit of the Bramble, one of most common and important wild plants. And let’s not forget the seasonal orchard fruit on which civilisation still somewhat depends, such as cooking apples:

However, according to tradition you should not eat blackberries after the feast of Michelmas, which is today, because legend has it the Devil spits on the blackberries! Well, whatever about the Devil, rodents of all sizes have certainly been up in the hedges eating them recently, and many blackberries have gone mouldy on the bush, so there’s probably a  lot of sense to this tradition. However, this year many blackberries are yet to ripen:

   There are certainly lots of moulds and fungi about. Some are drab, and some spectacular. Here is the Common Inkcap, which often appears on damp lawns in September:

Some fungus looks remarkable, such as the Bird’s Nest Fungus  which is named because each flower head looks like a nest with eggs in it, albeit an extremely stylised nest. I think they look like cupcake cake papers:

Although the days are now shorter than the nights, and temperatures are getting progressively lower, it’s one of the very best times of year to see butterflies because in order to feed they often enter gardens where flowers are still blooming, and where there are warm shelters and sun traps. This year has been a bumper one for the Comma butterfly in particular. Commas can easily be identified by their ragged wings. This one was perched on a white sheet, which really highlights the strange ragged appearance of the wings:

The Comma below is sitting on a Butterfly Bush. Some of these bushes are still flowering… but not for very much longer.

The most common butterfly at this time of year is the Speckled Wood, and it will usually be the last seen in Autumn. They are not known to hibernate but it wouldn’t surprise me if they are eventually discovered to do this:

At this time of year, due to the lower temperatures, the butterflies move more slowly and take the time to perch and open their wings in order to warm up. Butterflies can only fly when the temperature reaches 15°C, so basking becomes very important. Many species are known to hibernate. In Ireland Small Tortoiseshells can be seen entering houses, sheds and other buildings to hibernate in autumn and they can often be spotted flying on mild sunny days even in November:

Another species which hibernates, and only recently proven to do so, is the Red Admiral, which is a very bold and striking butterfly, and it will land on people too if they provide a place to rest in the sunshine:

And there is another species which shares these tendencies, although it seems this one also migrates – the Peacock butterfly:

Some butterflies actively migrate, such as the Painted Lady. It will fly south with the swallows and house martins. Thousands of them  filled the skies of Wicklow this year:

 

Some moth species also  migrate – mostly famously the Silver-Y. While it has been a great year for the Painted Lady it has been a disappointing one for the Silver-Y, but there are some about, flying in both day and night, and sometimes resting by windows at night:

There are still one or two Barn Swallows about, but mostly individual stragglers, older birds more experienced in the vagaries of intercontinental travel. Here’s one I saw flying south a couple of days ago:

Whilst most creatures breed in springtime, spiders mostly prefer autumn. And some spider relationships are quite complex – the male  Segmented Orb-weaver has to impress the female with a gift and she will only select him as her mate if the gift-wrapped gift is satisfactory. This one seems to have been successful and to have moved in with a female:

Slugs and snails also breed at this time of year, but they also mate in spring and all the way through when weather permits – here are two impressive Yellow Slugs, mating:

Slugs are hermaphrodites – each one is both male and female. However, in order to ensure genetic health they must mate – they must share their genes with others. The male in each slug mates with the female in the other. However, not all molluscs are hermaphrodites – cuttlefish, squid and octopuses have male and females – gender is a biological fact and a necessity.

Sadly, some of springs babies have not survived the year. Here is something which was recently drawn to my attention by the warden on the East Coast Nature Reserve  – a young Otter, presumably hit by a car on the Sea Road:

For those creatures that stay and winter in Wicklow there is ample opportunity to plan for next year – here are three Jackdaws inspecting chimney pots for suitable nesting sites – these could be siblings hanging about last year’s nest, but are probably last year’s breeding pair and one of their children. Many birds, including Jackdaws, serve apprenticeships with their parents, choosing nest sites, building nests and helping to get food for the young:

The Spring/Summer Intermediate

We’ve had a cold spring this year, and now we have reached the intermediate time when spring turns into summer. The first thing you will notice about this time of year is that, despite long days and sunny spells, there are few butterflies about. You might see one or two Orange-tip butterflies still on the wing,  but their time is now pretty much over until next year. They are beautiful though:

There are, of course, other butterflies around, but they are small in number, and mostly more drab species, such as the Speckled Wood,  which is a species I’m very fond of because it makes up for its lack of colours with attitude, being a cheeky butterfly that will ‘buzz’ you. However, butterflies aside, there are lots of other interesting creatures, such as beetles. In woodland glades you might find long horn beetles, aka timberman beetles, feeding on pollen. Here’s a very handsome species, Rhagium bifasciatum, which I found on a buttercup flower:

On the bogs along the coast of Wicklow there are many interesting creatures and plants to be seen at this time of year. There are warbler species and Stonechats are very brazen and beautiful in their breeding plumage – such as this male which regarded me suspiciously as I walked along the railway fence:

At this moment the bogs are covered in the beautiful blooms of the Yellow Flag, an iris species which grows in waterlogged ground and even in ponds. Many insects depend on them:

Keep an eye out for a very large caterpillar, which you might see crossing your path on a bog walkway if you visit a nature reserve. This wonderful-looking creature is the caterpillar of the Drinker Moth (Euthrix potatoria). The caterpillar is actually the source of the name, as it is said to be seen to drink drops of dew at this time of year,  a story that could have some truth to it, as folklore often does.:

The moth is much smaller than the caterpillar, but technically a large moth, as all of its relatives are quite big. The Drinker Moth is very stout and robust in a chunky sort of way. While you are looking for these caterpillars you might have a largish dragonfly zoom noisily past your ear. This will probably be the Hairy Hawker (Brachytron pratense), which is one of our earliest large dragonfly species. It is colourful and definitely hairy. I was very lucky to get a close-up shot of one only recently, and the camera lens was literally only a few centimetres from the dragonfly, which remained calm as it perched on a nettle:

Finally, a number of people have asked me if I could tell them what the amazing-looking  small blue-green beetles are that can be found on almost every flower along the coastal dunes in the last few weeks, as it is not easily found in books or online. That is definitely true. This beetle is the Blue-Green Soft-winged Flower Beetle (Psilothrix viridicoeruleus), which is a remarkably hairy little creature and seems to spend its time eating pollen and mating. Living the dream, I guess:

   Lately we have been having a very wet and cold time of it, and this does sometimes happen, with the weather far below par up until the Summer Solstice, which is the longest day of the year, but also the exact border between the seasons, ending the springtime and starting the true summer. The Summer Solstice this year will be this Friday at precisely six minutes before five o’clock in the afternoon in our local time, which is British Summertime (15.54 GMT). Many great summers started off as bad, if not worse than this one, so we can still hope for the best.

You Can’t Tax Your Way Out of Environmental Destruction

One month ago the United Nations published an official paper detailing the sheer level of destruction the natural world is suffering at human hands.

The same size as a honey bee, and very similar, but this is a Chocolate Mining Bee, which is probably the most common of all bees at this time of year. Instead of pollen sacs on its legs this female has special hairs which pollen sticks too, and which you can see here very clearly.

The U.N. divided the problem into three separate principal causes, starting with the direct destruction of nature, usually for financial gain. The second cause was indirect destruction by pollution, or other side effects of industry or human activity, which could be dumping of plastics in the sea or the clearing of land to build houses on, or any other number of side-effects. The third on the list was Climate Change.
However, by the end of the week most of the media had changed the story, suggesting that environmental destruction was a mere side-effect of Climate Change, and ‘pundits’ were clamouring for carbon taxes. This is very dangerous reasoning because carbon taxes are nothing much more than a licence to politicians to do absolutely NOTHING about environmental destruction, while making the lives of ordinary people more difficult.

Governments love taxes and will always be more than happy to impose them. The problem with carbon taxes is that they are supposed to be a deterrent, but big business and heavy industry, who should be taxed, will instead, with the complicity of politicians, externalise these taxes so that they are passed on to the public while they continue to pay as little tax as possible into economies of the countries hosting them. It doesn’t matter what the excuse, politicians will happily go along with any idea which allows them to tax the public – the public NOT Big Business.

It is very important to remember that most big newspapers and media corporations are owned by the same people who do most of the environmental destruction. They buy into media in order to push their own agendas. And state broadcasters are largely controlled by governments and therefore they too are controlled and must toe-the-line, and push the messages their political masters want pushed on the public.

A beautiful Gold Spot moth, which is on the wing right now. Keep an eye for them – they come to lights and night time windows.

The problem with carbon taxes is they amount to the turning of a practical problem into a mathematical equation, allowing governments to claim they are doing something, when they’re not, while allowing those who destroy the environment to continue to do so unopposed. Occasionally fines are imposed on the nation-states that pollute too much, or produce too much carbon, but they can then BUY carbon ‘credits’ from poorer nations which are not polluting. It’s all a completely ridiculous situation , and surely encourages environmental destruction?

A certain amount of pragmatism is always necessary – to live is to use resources. There’s no escaping that. But we should be aiming to stop destructive  practices, not creating carefully orchestrated systems which allow and encourage them to continue while forcing ordinary people to hand over their hard-earned money while giving them nothing in return. Because NOTHING is what carbon taxes amount to. Carbon taxes are the same as the selling of Indulgences, when the Church literally sold people places in heaven – they have no use here on earth. They are impractical and entirely corruptible.

If you really want to understand the problems the environment faces then the very best documentary on the subject is this 21 minute-long gem, the Story of Stuff, which is so good it will change your life:
