As it’s such a beautiful sunny weekend here in Wicklow I just want to remind people that spring has finally given way to summer, and the best evidence of this is that the Orange-tip butterflies have already disappeared. Here’s the last one I photographed this year:
There is always the chance of seeing one or two stragglers in certain areas, but it’s highly unlikely now we are midway through June. Also gone for this season are the thumb-sized queen Red-tailed Bumblebees although you have a better chance of seeing one or two stragglers of this species than an Orange-tip this weekend. And lastly I have seen the first real summer flowering, that of the first Butterfly Bush. Summer is here.
I have a lot more to blog about this weekend, but in the meantime, keep your eyes peeled.
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.
Anyone following this blog will realise it has been on hiatus since early March. Why so? Because although it looked like spring was breaking through, the winter became very long and drawn out. We had the coldest March since records began in 1882, and it was only two weeks ago that the temperatures suddenly became normal. Only the Monday before last ( a week and a day ago) did the temperatures rise above 15 degrees Celsius. All of this was caused by an easterly wind from Siberia, and then from the Arctic. This easterly lasted almost two months without stopping, which is extremely bizarre. Anyhow, things are now returning to normal and today was a balmy 18 degrees Celsius.
I have only seen three butterflies so far this year, two were Small Tortoiseshells and one was a Peacock (Inachis io) and both are species which hibernate. The Peacock is below.
Most importantly, many of the spring flowers are now blooming and the hardiest, the daffodils and crocuses, have already lost their blooms – the first phase of spring is over, despite the cold. However, now it is the turn of the trees to get their blossoms, and the first I saw since temperatures warmed up was the Red Currant (Ribes rubrum), a plant of the hedgerows, beloved by bees.
You know it is getting warmer when you see the Nursery-web Spider sunbathing. This spider loves sunlight, and has a very distinctive pose, which I have mentioned many times before as resembling Leonardo Da Vinci’s Universal Man, which also has eight legs…
However, for me the most exciting of all has been the appearance of the Tawny Mining Bee (Andrena fulva) and other species of solitary bee. You might remember reading, earlier in the blog, of how my garden became the first known established colony of this bee species in Ireland. That doesn’t mean they were not already here, just not known to be for certain. This week another colony was discovered in Co. Kilkenny and there are bound to be more of this handsome bee. I use the term “colony” lightly, because although the bees have appeared in large numbers, there is no single nest and each female bee takes care of her own nest and young. The males appeared first, and then the larger females, which they had to wait for to emerge from their underground chambers. The males are much smaller, and look almost like a totally different species. I will be doing a lot more about these bees in the next instalment… but you will not have to wait months for it. Tomorrow, if possible.
Finally, there are also plenty of bumblebees around. Usually the last to show up in gardens is the Carder Bee (Bombus pascuorum) and this for me puts the seal on spring. To the uninitiated the Carder Bee could be confused with the Tawny Mining Bee, except for one very clear difference – she is much larger. Here is the first Carder Bee I have seen this year, and have not seen too many since, but it takes a while for a hive to get going.
