Biodiversity Week!

You probably don’t realise it with all of the big news stories, referendum issues, etc. but this is Ireland’s National Biodiversity Week, and here is a little celebration of the biodiversity you will see in Wicklow right now, in no particular order:

   This is my first proper photo of a Red Kite (Milvus milvus), a large and very beautiful bird-of-prey which mostly feeds on carrion, and can often be seen soaring above the roads of Wicklow on the watch out for roadkill. It is a huge bird, and has only been back in Ireland for about a decade having been reintroduced, with the first released in Wicklow. They have since thrived.

Wicklow loves its cherry trees, and in spring they are everywhere blooming. Here’s a handsome double-flower cherry. Most are now gone out of bloom but you might still find some stragglers.

After the mass blooming of dandelion flowers seed-eating birds come into their element, with beauties such as the Goldfinch (Carduelis carduelis) and Bullfinch (Pyrrhula pyrrhula) coming into gardens to feed on them. The bird in the photo is a male Bullfinch.

Butterfly numbers have been steadily climbing in May, and these dainty creatures can be found almost everywhere. The one in the photo is easily identified as it is the only Irish species with eye-spots, the Peacock butterfly (Inachis io).

Apple trees doe very well in Ireland, and Wicklow has no shortage of them. Here is one with immense blooms. Once fertilised by a pollen-covered bee or hover fly, each flower will gradually develop into an apple, but it will take a few months. And here’s a close-up of the beautiful blossoms.

Here (below) is one of the best of all the pollinators and in 2018 it seems to be enjoying a population explosion in Wicklow – the Chocolate Mining Bee (Andrena scotica), which doesn’t mine chocolate, but is chocolate-coloured. It is often confused with the Honey Bee (Apis mellifera) but has no pollen sacs on its hind legs, and no sting. The one in the photo is collecting pollen from a potentilla flower.

May is the time of the Maybugs – large, clumsy beetles best known as Cockchafer (Melolontha melolontha), which emerge from pupa having spent a year or two under ground as large white grubs feeling on the roots of dandelions. They appear in May and June and fly about at night, and are attracted to lights. You will see them now almost every night until the end of June.

And, of course, there are also moths to be seen:

   Many moths, like the one above, are attracted to window lights at night. This handsome species is the Small Phoenix (Ecliptopera silaceata), which is quite common in Wicklow, and which appears as two different generation of moths. This one belongs to the first, and in late summer a second generation of moths will appear.

On leaves all around gardens in Wicklow little green eggs appear. Some belong to moths, some to butterflies, some to true bugs and some to beetles. These eggs (above) belong to the Green Shieldbug (Palomena prasina).

Finally, to end my little showcase, here is a very beautiful game bird, the Wood Pigeon (Columba palumbus). These birds used to very much belong to the countryside, but in recent years they have begun coming to live in gardens, and can even be found in the centre of Dublin city, especially in universities with trees and green areas, such as Trinity College. However, in Wicklow they are in much larger numbers.

 

 

Fledglings and Maybugs

It was a tough spring for the birds because temperatures were almost relentlessly below normal, causing plants to bloom, blossom and leaf late, and insects to be in short supply. I was surprised to see the Blackbird above with such a large fledgling chick. I had put some cream out for them, cream which had just gone off, but they loved it.

Last Thursday was our first really warm sunny summer-like day and later that night I found Maybugs, better known as Cockchafer Beetles, coming to the lights of the house in huge numbers. In fact, I’ve never seen so many at one time. They will be flying around Wicklow skies until late in June, and possibly even into July.  They are heavy beetles and when one very big one accidentally blundered into the web of a female Giant House Spider the poor spider was quite at a loss what to do, as the beetle was a bit bigger than its usuall prey. The Cockchafer fell out of the web soon after, ably assisted by gravity:

When spider dreams come true they're generally too big to handle.

National Biodiversity Week

Usually National Biodiversity Week in Ireland begins on a Saturday and ends the following weekend. However, this year it is a two-week event which began the week before last and will be ending next Monday, June 1, the June Bank Holiday. However, it was only late last week that the cold Arctic winds abated and a tropical current took over, and what a weekend we had. The birds are nesting now and are interesting to watch – such as these Jackdaws nesting in one of our chimneys:

Also, the insects are now making their presence felt – keep an eye out for this creature:

This is a male Poplar Hawkmoth, which is the largest moth most people see in Wicklow, and not all that often either. But they are always around.

This is the largest moth species most people encounter in Wicklow and is far bigger than people expect Irish moths to be –

In daylight hours this moth can be handled easily and is not usually stressed in the least bit.

However, although it’s large there are several much larger species found in Ireland, and the largest that does visit Ireland, albeit only occasionally, the Death’s Head Hawkmoth, is about twice the size of this species and far more robust.

Moths are not the only large insects flying about our short late May nights – you can still find Maybugs, aka Cockchafer beetles blundering about and crashing clumsily into windows, cars and the occasional forehead. They are not our biggest beetle species, but they are probably our most common big beetle species, but they fly for only a short time in late spring and early summer, spending most of their lives as white grubs feeding on the roots of plantains and dandelions.

Many people find the large Cockchafer quite frightening, but it is completely harmless and spends its relatively short adult life searching for a mate.
