August Colour and a Little Rain

There were times in July when there was some worry we could have a drought, but after several bouts of rain over the last couple of weeks those fears have been allayed and the sunburnt lawns have recovered. However, one of these rainy periods is coinciding with the August Bank Holiday, which is usually the high point of the Irish summer. Thanks to all of the good weather, and some helpful rain, we are having a great summer and a colourful one. There are many interesting creatures about. You might find circles cut from rose leaves, both wild and cultivated forms, and you might also see a leaf flying through the air, carried by the Leaf-Cutter Bee, a beautiful solitary species.

The species in the photo, which is the most likely one you will see, is the Patchwork Leaf-cutter Bee (Megachile centuncularis) which likes to make nests in nail-holes in fence-posts which it stocks with leaves for its larvae.

There are also lots of dragonflies and damselflies around, and many will fly along hedgerows, green areas and even gardens with or without ponds, although they all need ponds or slow moving rivers in order to breed. Some damselflies are very dainty, and they can be difficult to tell apart from one another. This one was in a meadow garden, and it is almost certainly an Azure Bluet (Coenagrion puella), and is a very handsome species which can easily go unnoticed despite being as long as an adult’s little finger:

   There are some very interesting little creatures which you can find absolutely everywhere right now, in meadows, gardens, hedgerows and pretty much wherever there are flowers. These are Pollen Beetles (Meligethes aeneus), tiny beetles which can be seen in almost every flower everywhere across Wicklow right now. They are important but barely-noticed pollinators of many species of plant and they often appear in huge numbers. Here are quite a few of them in a poppy:

Butterfly Fly-bys

Some butterflies and many moths have short flight periods. They spend most of their lives as caterpillars and only become butterflies or moths in order to find mates and lay eggs. We are coming to the end of the flight season of one of these butterflies right now, the Ringlet (Aphantopus hyperanthus). This butterfly like long grass in open areas such as fields or meadows, so it’s a little off the beaten track for most people to come across. It’s also quite dark. Here is a male, which is quite handsome and has a white edge to its wings which looks quite impressive:

The female is slightly more brownish and less bold.

Another summer butterfly which lives in a similar habitat, but which flies mostly throughout July until the end of August is the Meadow Brown (Maniola jurtina). Although not very brightly-coloured they are very handsome, but rarely sit still for too long except in the tall grasses of meadows. Here is one which, unusually, has stopped to feed on a buddleia bush:

   You have up until the end of august to see this butterfly, but if you want to see a Ringlet you have only a matter of days.

Despite my efforts to find and photograph an Elephant Hawkmoth it seems that the window of opportunity for this year has run out, or just about, and I will have to wait until next year. However, there is no shortage of food for the enormous caterpillars, which jungles of its beloved rosebay growing all around Wicklow, especially on the eastern seaboard, as you can see here:

Sometimes rosebay can grow to almost three metres tall!

Year of the Comma

In 2011 we had the so-called Summer of the Painted Lady due to a population explosion of that butterfly species which arrived in the British Isles in hundreds of thousands, if not millions of individuals. This summer in eastern Ireland we have a population explosion of another species of butterfly, the distinctive and beautiful Comma (Polygonia c-album). It is a bright rusty orange colour and flies extremely fast, and when you eventually manage to see it paused to rest and sunbathe on a leaf you will probably think somebody cut its wings into odd shapes with a scissors, because this butterfly has very odd wings:

   The undersides of the wings are very dark and drab, but look like dried leaves. However, there is one bright white mark on each lower wing in the shape of a comma punctuation mark, which is how this remarkable-looking butterfly gets its name:

So it’s a very exciting summer so far, and it’s only reaching the high point.
