The Autumn Equinox

Tonight, and only a short time ago,  at 9.02 am local time here in Wicklow (8.02 pm GMT) was the exact halfway point between the Summer Solstice and the Winter Solstice. To put it bluntly, this is the definite end of summer and start of autumn, and from now until the Vernal Equinox next March each day will be shorter than the night. And the birds know that, so they’re fattening up, increasing their energy reserves by eating the various berries on the myriad trees and bushes which are brimming with them right now. Here’s a photo I got of a male House Sparrow (Passer domesticus) feeding on blackberries:

   And now butterflies are disappearing fast, although there are Large Whites, Green-veined Whites, Red Admirals, Peacocks and Small Tortoiseshells still to be seen in small numbers. The latter two will hibernate and need to find suitable accomodation relatively soon if they are to make it to spring. However, the most numerous butterfly at this time of the year, and the one that blends in best with the autumn colours, is the Speckled Wood, which is usually the last species seen along hedgerows in the autumn. Their numbers are falling too, though. This September has been cooler than those we’ve had in recent years and that’s probably a factor.

But, if any creature plucks the heart strings more than others as it disappears from the landscape it’s the Swallow, You can still see some in our skies, but they’re flying south-east at speed, and usually not playfully hunting for insects as they were a few weeks ago. Now they have no time to waste and need to get to southern Europe and across the Sahara Desert to southern Africa with some degree of urgency, as the insect population on which they depend crashes in the colder, less sunny climate of autumn. There’s still a lot to enjoy out there though, and I’ll be doing my best to showcase it. Here is my slightly out-of-focus photo of a Swallow flyng quickly south,  and quite high up, this morning. I guess this is farewell and bon voyage, until next March or April:

 

Heritage Week

Tonight at midnight National Heritage Week starts and runs until Sunday, 27th August. There are events celebrating Irish heritage all over the country and Wicklow has many too. This year the emphasis is on my favourite subject, natural heritage. However, as usual every kind of heritage is covered. You can see a full list of events here: http://www.heritageweek.ie/

Even if you don’t attend any of the events, or if you attend all of them (not really possible) you can celebrate natural heritage in your own way. I’m starting by photographing moths tonight.

   Here are some interesting ones I’ve already found, and which you can see tonight too, as they’re very common. Firstly the beautiful Mother-of-Pearl moth (Pleuroptya ruralis), which I’ve written about recently. It really does look like its wings are made of mother-of-pearl as they have the same sort of shine as the inside of an oyster shell:

And here is a lovely moth called the Hebrew Character (Orthosia gothica) as it has a marking on its wings which look somewhat like a Hebrew letter. The caterpillars of these moths can commonly be found on lawns in spring, and sometimes even during winter months.

The Butterfly Extravaganza

Somehow, yet again, we’ve reached the middle of August and the days are getting noticeably shorter, but they’re still long and warm despite there being a bit of rain about. We are now at the peak of the summer bloom, and this is when you will see the most butterflies and most kinds of butterflies. Keep a look out for the Painted Lady (Vanessa cardui), although we don’t have a lot of them around this year.

The Painted Lady is found across Europe and Asia and even in North America and is a migrating species.

This summer we have had an abundance of Peacock butterflies (Aglais io) which are very popular with tourists from the Americas and I have been told on more than one occasion by American tourists that when it comes to seeing and photographing butterflies, the one they most want is the Peacock. And who could blame them – it’s absolutely stunning.

However, a very close second when it comes to popularity is the closely-related, but quite different looking Small Tortoiseshell (Aglais urticae) , another Old World species much prized by wildlife photographers from the US and Canada.

Personally, I think they are all equally beautiful and the fact that you can often see them all flying together at this time of year, feeding on soil minerals and bramble blossoms, not to mention Butterfly Bushes (Buddleia davidii) and many other plant species, makes them even more special. There are also other beautiful butterflies which occasionally fly among these butterfly species and I hope to see and photograph some of them before the summer is over. Make sure you get out and have a good look at the butterflies this summer, while the spectacle lasts. In two or three weeks the numbers will begin to drop so make the most of it.
