We’ve had a very cold wet autumn and now a good chilly winter has arrived. Today is Christmas Day and we had a superb bright and sunny morning due to cool, clear skies. There was a good frost this morning. Here is a video I made of bees feeding on blooming mahonia. Mostly they are the hardy White-tailed Bumblebee, Bombus lucorum, with some very big examples. This bee commonly flies in winter. But there was also one Honey Bee in there, Apis mellifera.
May is always a bit of a mixed bag. You never know quite what you’re going to get, but it’s always progressing towards the calmer months of summer. And in the natural world it’s a time of frenetic activity. This year we had May weather in April because the weather was so unusually dry for spring. First it started with early bird nesting.
But the most important aspect of the spring, apart from the weather, is the mass flowering of various plants. The most important is the spring dandelion bloom. Dandelions provide huge amounts of pollen that many insects depend on, especially our pollinators. Every conceivable species of bee, fly and many beetles depend on these flowers in the early part of spring. In May they reach a crescendo in their blooming and then rapidly seed while other spring blooms appear just in time to sustain the insect population. Here you can see dandelions and bluebells together:
The Bluebells are now mostly gone out of flower in the lowlands, but up in the highlands of Wicklow they are only coming into bloom, so if you’re looking for bluebells this late in May then you need to go upland. Tawny Mining Bees among many other species depend on these flowers. The Tawny Mining Bees are gone for this year, but you might see another pollinator about, the somewhat sinister-looking and beautiful Panzer’s Nomada (Nomada panzeri) a cuckoo-bee which parasitizes the mining bees. It is also known to have a bad sting, but this one was very calm and unthreatening:
Also, May is the time to see the Orange-tip butterfly (Anthocaris cardamines). The females are all white with very few black dots on the upper sides of their wings. The males have are identical but have stunning orange markings on the tips of their forewings.
However, from below both the male and female Orange-tip look very different to other white butterflies, having a green marbling pattern which gives them camouflage.
As the weather gets warmer more and more moths appear too, but keep a look out for caterpillars, because many of the caterpillars of moths found in Wicklow are far more spectacular looking than the adults of the same species. Here, for example, is the caterpillar of the Yellow-tail Moth (Euproctis similis). The moth is plain pale white with a bright yellow abdomen tip, but look at the gaudy colours of this caterpillar found on a Cistus bush:
Along with dandelions the other big bloomer where the bees depend on is the big spiny Gorse or Furze bush. The yellow flowers fill the air with the scent of vanilla. Unfortunately in dry conditions they are highly flammable, but now we are at last getting some decent heavy rain showers the danger is passing. Some parts of Ireland have suffered terrible Gorse Fires this year. But fortunately Wicklow has escaped the worst of it:
Unfortunately the first post of this new year must be a sad one – I have just learned that one of Wicklow’s best known naturalists, Stan Moore, passed away on the last day of 2016 after an illness. Stan wrote the column Nature’s Corner in the North Wicklow Times for many years. He had an all-encompassing interest in nature, was a brilliant artist and produced lovely oil paintings, photographs and videos of the natural world. The first time I met him he came to my house with an illustration of a fish he had found, and needed to look at some of my books to positively identify it as it was a strange one. A few years later I recorded him being interviewed by a journalist for a programme which was aired by the Greystones Community Radio Project, and if I can dig that out I’ll put it on the blog. Sadly I did not take up photography until later, so I have no photo of the naturalist. Rest in Peace Stan!
This January is very different to last year – instead of the incredible wet weather caused when Ireland was struck full force by last year’s severe El Nino event we have had long dry spells, and some of them have been quite balmy. This had apparently caused the vegetation to get very self-assured, and as early as the 9th of December I saw my first daffodil leaves breaking the surface of the soil, and now many of them are well above ground and soon to bloom:
And if that wasn’t enough the pennant-like leaves of Arum Lilies have begun to unfurl:
And today I spotted dozens of Alexanders which had broken through the ground and come up all leafy along a roadside verge – Alexanders normally don’t appear until February at the earliest:
However, most surprising of all is an Elder tree which has sprung fresh green leaves all along the ends of its topmost branches:
So the question is, are we getting an extremely early spring? Can the plants predict, or are they just reacting to the immediate circumstances. The short answer to that question is that I don’t know. Last year’s freak wet weather, followed by this year’s very dry weather could have thrown the natural world off-kilter, but plants have had millions of years to evolve an ability to predict and behave accordingly, so perhaps the smart money should be on an early spring. But I have seen all of these plants struck by sudden cold spells before, and killed, and the only plants I have seen in my garden which never appear until the winter has finished its work are a certain group of wild (feral) Early Crocuses. Until I see them I’m not convinced the weather is definitely on the up. However, in the meantime the amount of wildlife to be seen is growing. A few days ago I spotted a male Winter Moth (Operophtera brumata) on a wall by a window light. It was actually more brownish than it appears in the photo, but the camera flash had a strange effect on the colouration:
There are also caterpillars of spring and summer moths to be found at this time of year, most having hatched from their eggs in late autumn. They eat and sleep all winter. Here is a handsome green Angle Shades caterpillar, and two smaller Large Yellow Underwing moths, all of which will get much larger before becoming moths:
Because the nights are so long keeping birds asleep, and there are few other invertebrate predators around in winter, slugs can be often seen in huge numbers on warm dark winter nights. Some of them can be very handsome. Here, for example, is a medium-sized species known as the Dusky Slug (Arion subfuscus):
And this distinctive species is a relatively recent arrival, the Budapest Keeled Slug (Tandonia budapestensis), which was first identified in the British Isles in the 1920s, probably carried in on plants:
Slugs might not be to your taste, but if not then there are still quite a few bumblebees to be seen feeding on winter-flowering garden plants such as Mahonia and Vinca. Here is one I saw today, with noticeably full pollen sacs on its legs, a Buff-tailed Bumblebee (Bombus terrestris):
Only time will tell how this winter pans out, so in the meantime Happy New year!
