Spring Flowers

We have some April showers at the moment, but since the Equinox on the 21 March the days have been pretty nice and warming up well. Spring moves from the ground upwards into the canopies of the trees, so that the undergrowth blooms earliest and then the insects begin appearing, feeding on the nectar and pollen that is available.

Primroses - Primula vulgaris - blooming. These are among the most hardy spring flowers, sometimes blooming beneath snow. There was no snow this year, thankfully.

Keep an eye out on the flowers for the insects, especially different species of bees. Spring is the time of the Mining Bees, and there are a number of different species, but the most commonly seen in Wicklow is probably the Mining Bee - Andrena haemorrhoa.

At this time of year the larger trees and bushes begin to blossom and their fragrances are now beginning to fill the air, and they contribute very much to the distinctive fragrance of the spring air. One of the most impressive of these bushes is the Flowering Currant - Ribes sanguineum - which is found throughout Wicklow in lowland areas and has beautiful flowing tresses of pink flowers.

Flowering Currant as you will see it at the moment along hedgerows and even riverbanks. Unfortunately I cannot reproduce the scent for you via the internet, but one day it may be possible, and that will be quite an adventure,

Now that there is nectar to be had, keep an eye out for moths at the windows at night time. More and more are showing up, day-by-day, and one of the most common is the Hebrew Character – Orthosia gothica.

The Little Things Of Life

Spring is now gathering pace, and the days have grown to be almost as long as the nights. This week the Azores High has arrived over Ireland, bringing us clear skies – gorgeous warmish sunny days and frosty nights. But the warm days have caused insects to appear and there is a population explosion of Seven-spot Ladybirds (Coccinella septempunctata). They can be seen basking on trees, shrubs and walls all across Wicklow right now.

ANot quite so noticeable as these bright red ladybirds, but almost as numerous, are Green Shieldbugs (Palomena pristina) which have truly awesome camouflage. In summer they are bright green, but in winter become dead-leaf brown. Most are still that colour right now, but will soon become brighter.

One especially interesting insect I’ve seen this week is a type of moth, the Dotted Border (Agriopis marginaria) is a little bit smaller than a butterfly, and very similar in appearance. It is a late-winter/early-spring species and so you have only a few more weeks to see them this year, if even that much. They readily come to light. The one I photographed is a male, and this is easy to tell because of the typical feathered antennae, but also because the female of the species has only stubs for wings, and must walk about on foliage wafting pheremones on the air so that she can be found by the male. Keep an eye around window frames for these guys.

Dotted Borders are quite drab-looking but have a distinctive row of dots along the edges of their wings. Males come to windows by night, attracted to the light, apparently due to a chemical emitted by lightbulbs which is very similar to the pheremone emitted by the female as an attractant.

Bees and Frogs

In the last few days a small number of Honey Bees (Apis mellifera) have been arriving in gardens to collect pollen from the early blooming flowers, of which there are quite a few these days. Getting a half-decent photo in the early light of spring is another story, but I think I just about managed one or two.

Two days ago I found my first frogspawn of the year, although there are reports of it from all over Ireland at this point. Frogspawn always puts the seal on spring. But spring is also a long and dramatic change in Wicklow, and my own favourite time of year. In Ireland we have only one species of gfrog (so far), the European Common Frog, Rana temporaria, but there is also one species of toad, the Natterjack or Running Toad, Epidalea calamita, which is so far only found in the southwest of Ireland, mostly in Kerry. But we also have one other amphibian species, which is found in Wicklow, the Smooth Newt, Triturus vulgaris, and I hope to get some decent photos of this species this year, although it is difficult to see in ponds, being quite small and shy.
