In the Wake of Hurricane Ophelia

Wicklow had a very lucky escape when Ophelia struck Ireland yesterday. All across the county there were trees down, and almost everybody lost their electricity at some point. However, three people lost their lives directly due to the storm and my thoughts are definitely with their families, and considering how many people are trapped in rural areas of Ireland without electricity, water and possibly with no means of communication, then this death toll could very easily rise. So, if you are in one of those areas and happen to read this on your mobile phone, do check on people in your area. Elderly or disabled people in particular might not be able to draw attention to their predicament. And beware of broken trees and powerlines.

As Hurricane Ophelia began to move towards Ireland late last week and over the weekend the weather became both very overcast and unseasonably warm. On Friday night temperatures were 17 or 18 degrees Celsius (65 or 66 degrees Fahrenheit), depending on where you were. These night-time temperatures would be far more normal in a balmier Irish summer, but were very much out of place and unpleasant in mid-October. On Saturday night misty drizzle began and extended into Sunday, and as a result frogs could be found hopping along footpaths or outside the doors of houses, just like this camera-shy one I came across:

Met Eirinn, the meteorological service (weather forecasters) for Ireland had predicted that the structure of Hurricane Ophelia would change before it struck Ireland. It had been a Catergory 2 hurricane when it began moving north from the coast of West Africa, but nobody expected it to increase to a Category 3 hurricane (there are only five categories) or remain that for so long. It was only about 500 kilometres south of Ireland when it finally began to change shape and turn into a sub-tropical cyclone, but it had lost none of its energy as it struck the island. Just before this happened there was a sudden and mysterious abundance of moths coming to windows. Only a few hours before the winds arrived I saw this beautiful Angle-Shades (Phlogophora meticulosa) perched on the wall by the back door light:

 

I had expected there to be a sudden rush of large House Spiders towards the house just prior to the storm, and during, but this never occurred and it seems the spider season has already come to an end this year. Some people will undoubtedly be happy to hear that. It’s possible that the frogs and birds consumed many of these spiders . There were birds hiding from the storm in sheds and outhouses, and even disused chimneys. Most small birds will eat spiders, and frogs certainly take them if they come across any.

With all of our incredible technology it is very easy to forget how fragile we are. We take electricity for granted, and not having any for any length of time is a shock to the system, especially in darker times of the year. To makes matters worse, many parts of Ireland require electricity to pump tap water and sewage systems, yet don’t have generators available to back up these systems. When a storm like Ophelia occurs we get an unpleasant reminder that mankind does not rule the natural world, but is itself ruled by nature.

Fortunately today was dry and sunny almost everywhere, and it was so calm that it was hard to imagine how dangerous things were yesterday. In fact, I was astonished to see a Red Admiral (Vanessa atalanta) butterfly flying about in the warm sunlight this afternoon, even though it was only 14 degrees Celsius in the shade. I managed to get a decent photo as it sunbathed on ivy.

And there was a very beautiful sunset tonight, but it is now much colder than it was before the tropical air of the hurricane came our way, and tonight we are to have proper October temperatures, or maybe even temperatures more like December. Many trees still have their leaves. Many, of course, don’t. Without their shelter winter will probably come early this year.

 

Autumn Surprises

At the end of every summer I usually have a few regrets, mostly places I didn’t go, creatures I didn’t see, and photos I just missed. One of my regrets this year was I didn’t see so much as a single Hummingbird Hawkmoth (Macroglossum stellatarum) all spring and summer. And then it happened – the Autumn Equinox was gone and it was getting cooler, and one bright sunny morning (late morning) a Hummingbird Hawkmoth flew past me and landed on a Butterfly Bush to bask in the weakening sunlight, allowing me to sneak up and get a macro of what looks, to the casual observer, like a large and very unspectacular moth. Of course, we all know differently:

   But that wasn’t all – this spring and summer, for reasons which never revealed themselves, I didn’t see one Beaked Hoverfly (Rhyngia species). And then one appeared as if by magic only moments after the Hummingbird Hawkmoth had flown away, feeding on a cultivated convolvulus flower:

This year there are plenty of hoverflies to be seen, even now. There has been a mass blooming of dandelions this autumn, currently underway, and many handsome species can be seen feeding on them. And their favourites, the convolvulus flowers, are still blooming in many places. Here is the very common hoverfly species Syrphus ribesi feeding on Hedge Bindweed (Calystegia sepium). However, it seems some of the predators which stalk these flowers are still about – I didn’t notice it when I took this photo, but look at the white object beneath the flower. Do you know what that is?

This bright white beast, which looks like a fallen petal, is a female Flower Crab Spider (Misumena vatia) and the hoverfly is very lucky it had left the flower as it almost certainly would not have seen the spider until after it had been caught by it. Autumn, more than any other time of year, is dominated by spiders. Flies beware!

July Moths

Some butterflies only fly for a number of specific weeks or months, but the same is also true for quite a number of moth species found in Wicklow. There are a few you might want to keep an eye out for, as they fly mainly only in July. Probably the most noticeable is the beautiful Swallow-tailed Moth (Ourapterix sambucaria). These moths normally take to the skies in late June and fly throughout July, but disappear by the end of the month. There is still a small chance of seeing this butterfly-like, butterfly-sized moth:

The Swallow-tailed Moth usually appears along hedgerows or in gardens about half-an-hour after sunset, and it flies swiftly at head height, rarely stopping. However, wait long enough and you might find one feeding on flowers, or, if you are very lucky, one might rest on a wall in the light of a window, as in the case of the one pictured.

Another common species, but smaller, is the Small Magpie (Anania hortulata), which is extremely common along hedgerows and ‘waste ground’ and can be seen flying soon after sunset and even occasionally in daylight when foliage is disturbed. This beautiful moth flies from June until the end of July, occasionally into  August.

However, there are moths which can be found flying throughout the summer, and some of them are very beautiful and very common. One of these is the feathery, fairy-like White-plumed Moth (Pterophorus pentadactyla) which will fly from June until the end of August, and even into September. Look for it in gardens on lawns, and along hedgerows. Like the Swallow-tailed moth it seems to glow in the dark, even though this is due to the brightness of its colouration and not actual glowing.

The White-plumed Moth pictured was attracted to light at a window. They don’t often come to light, usually preferring very dark areas of gardens.

Another moth which is extremely beautiful and found all summer, but which is less easily seen, is known only by the scientific name Carcina quercana. I usually call it the ‘Poncho Moth’ because its wings resemble a poncho. You will find this creature along hedgerows but also along river banks and sometimes meadows near the sea. It has extremely long antennae.

This Poncho Moth landed on a car parked beside a river.
