The Earliest Spring Ever!

Last night we had a severe frost in Wicklow, but it seems the plants have decided, for whatever reason, that spring is here to stay. I have never seen anything quite like it. On New Year’s Day I found Bluebells throwing the leaf-litter off and raising their juicy leaves to the sun.

And not only were the daffodils up, but irises had poked their blade-like leaves through the soil, and the crocuses were not only well up above ground but some now have flowers on the verge of opening.

A crocus about to blossom, as I photographed it yesterday.

Okay, so maybe you’re thinking these impetuous plants are mistaken: crocuses can sometimes bloom in the snow, as can primroses, and daffodils often make mistakes. Fair enough arguments, but have you ever seen cherry blossom in January? There are certain October-flowering Cherry trees, but not January ones, and the pair of cherries growing out front of the church (opposite the petrol station) in Newcastle village would seem to me to be the typical spring variety. True, they are in sunny areas, but covered in blossoms and being attended by big Bumble Bees. Incredible!

According to the weather forecasters we are in for another week of cold frosty nights and mostly clear sunny days, so winter is certainly not done with us yet. But spring is here, whatever the weather. And just to end, keep an eye out for the beautiful feather-duster like, aniseed-scented blooms of the Winter Heliotrope. They are in abundance this year, and they have to be as there is so much competition.

Winter Heliotrope flies the flag for winter, while it still can.

And after a great 2012, with the massive successes of Wicklow boxer Katie Taylor and cross-country runner Fionnuala Britton, it seems the very landscape itself has decided to throw a celebratory party. 2013 is off to an awesome start.

Extinct Bee! – a slightly crazy story

Some of my readers and viewers might remember the photos I posted of the beautiful Tawny Mining Bee (Andrena fulva) I posted in early April: http://www.gardenofireland.com/workbook/?p=649

In the article I was highlighting the incredible complex of burrows on my front lawn, extending for many square metres. But there was an incredible twist to this story which I only became aware of last week when I received and read the autumn bulletin from the Biodiversity Data Centre in Waterford. Dr. Úna Fitzpatrick was delighted to inform readers that:

“The most exciting bee story of the year was the rediscovery of the extinct tawny mining bee (Andrena fulva) by Roger Goodwillie in Co. Kilkenny. This species has only ever been recorded from Co. Kilkenny and was last spotted by Arthur Stelfox in 1925.” (BI Issue 10, pg. 12.)

The ‘extinct’ Tawny Mining Bee. I took this photo in my garden in 2010.

Needless to say, this story took me by surprise and showed just how ignorant I was of the range and status of species in Ireland, because I had seen this species in my garden for many years and both my brother Trevor and I had been photographing them since April 2009. They were never particularly numerous, but this year there were over two hundred burrows of this ‘extinct’ bee in my lawn alone. And when I contacted Úna Fitzpatrick she was very, very surprised.

I also had video:

But that is why the work of the National Biodiversity Data Centre is so important. If you see something you think is unusual, or which might be rare, or even ‘extinct’, then visit the website www.biodiversityireland.ie and contact the relevant person and check out their records and submit your own.

 

Wicklow’s Spring Biodiversity Explosion

As April draws to a close we have reached high Spring, and this year has been a superb one. The steady weather conditions and good levels of sunlight have transformed the landscape. The shrubs and trees are beginning to bloom, adding to those of the undergrowth. This year the lilac trees have been early and especially impressive due to the dryness – in wet years the fleshy, fragrant flower-spikes rot rapidly. This year they are the magnificent ornaments they are meant to be.

But the undergrowth is only really getting started. In woodlands, and on the narrow lanes of Wicklow you will find intoxicating seas of Ramsons (Allium ursinum), the wild garlic. Driving along these lanes with the car window rolled down can be something of an aromatic adventure in springtime.

Ramsons or Wild Garlic

The flowering plants depend on sunlight, and in turn the invertebrates, particularly insects, depend on the flowering plants to provide serious energy, in the form of nectar and pollen. Of course, the plants are equally dependent on the insects to fertilise them so there will be more plants, and insects, next year. Away from the trees the Daisy (Bellis perennis) are one of the most important nectar-producing species, supporting every conceiveable pollinating creature, and reaping the rewards. Wild meadows are very important habitats for this reason.

As the length of days and exposure to sunlight increases the number of plant species in bloom greatly increases, which in turn supports more and more pollen and nectar-dependent organisms.

This, in turn, leads to an increase in predator numbers. One of the most interesting and unusual predators of other insects is the Yellow Dung-Fly. These flies are normally seen perched on cow dung in huge numbers, where they mate, lay eggs, and attack and eat other insects attracted to the dung. However, in spring they feed mostly on pollen, because there is so much of it about, and their prey numbers are still growing. The fly in the photo is covered in pollen, having clearly gorged, probably on daisies.

Yellow Dung-Fly (Scatophaga stercoraria)

Because of predators nectar and pollen-feeders have to be able to defend themselves: in spring you will see many species of bee, all armed with potent stings.

Bombus pascuorum is a distinct bumblebee species with a very long probing tongue, which allows it to fertilise many flowers no other insects can...it is vital to the environment. Here is is seen feeding on dandelion.
Nomada bees are small, solitary species that look very like wasps, but are extremely shy and best seen feeding on apple blossom. They are quite curious and will "people watch".
A female Mining Bee (Andrena haemorrhoa), a solitary species commonly seen in spring, where they build little tunnels in lawns and meadows, with small vocanic-looking cones around them. This species collects pollen on special hairs on its hind legs, as you can see in this photo.

However, many of the bees you will see in Wicklow are not bees at all. Instead of developing toxins, many species of fly have opted to imitate bees, and it is difficult even for naturalists to tell them apart. The trick is to look at the heads: the flies have large round heads with little or no fur, and they have only stubby antennae, whereas bees always have long antennae curling from their heads.

However, flowers do sometimes get more than they bargained for, slugs will also happily eat pollen, and the entire flowerhead. But only very, very slowly, and very occasionally.

Thanks to the abundance of nectar many insects can take time off to find mates and breed, something that would be impossible to do if they didn’t make a profit when it comes to feeding. The beautiful little Orange-tip butterflies are only with us for about four or five more weeks, so watch out for them in gardens, along roads and flower-filled meadows with good hedgerows. They are now taking the time to find mates and breed, and the sight of a pair of them dancing over hedges is a strong sign you will very soon witness a marvellous event: I saw Orange-tips mating for the first time in my life this week. They are so common at this time of year, it is strange how well they hide their social lives. Maybe they’re marvellous camouflage prevents the casual observer from noticing. However, I’m not a casual observer, so it is rare: if you do witness this event you are one of a lucky few.
