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.

 

 

October Twilight

October is a very strange time of year – September seems like an extension of summer, but colder, and then very suddenly October arrives and the flowers of summer begin to die off, the leaves yellow, or redden, or both, and fall off deciduous trees as the nights grow longer than the days. Everywhere gets gradually more muddy as leaves, flowers and berries decay on the ground.  But there is still a lot to see amid all the nostalgia of another year growing to an end.

There are still some Swallows flying about on their journey south back to Africa. It's a good time to see and photograph them as they perch on wires. The light might not be so good though.

At this time of year our swallows, the Barn Swallow (Hirundo rustica), tend to perch for long periods to rest their weary muscles before making their autumn migrations. There were definitely fewer of them around Wicklow this summer, which is slightly worrying as something must be preventing them arriving safely in Wicklow.

The Autumn Hawker dragonfly usually arrives in August to hunt butterflies and other insects. This year they didn't arrive until mid-September and you can still see them patrolling footpaths and garden driveways.

Ironically our autumn was better than our summer this year, although not quite as warm, although certainly more stable. Eventually the annual arrival of big dragonflies occurred, the Migrant or Autumn Hawkers (Aesna mixta) and there are still a few around, although very difficult to photograph or video as they fly. I usually watch one land and slowly approach to get a good photo. If you move slow they will remain still.  But there are some other very interesting insects around, and some are both interesting and slightly creepy, such as this one:

A noctunal visito to a window, this large and handsome insect is a Burying Beetle.

Burying Beetles are quite closely related to chafer beetles (like the Cockchafer) and dung beetles, like the Common Dor Beetle. However, unlike these beetles, Burying Beetles lay their eggs in corpses which they find in the countryside, and they actually bury the animals they find underground. They are very intelligent creatures and very recently it was discovered (with the aid of special cameras) that they keep their larvae in nests and will feed them mouth-to-mouth, as birds do. Even more remarkable, the young ‘tweet’ when they’re hungry. This extremely handsome species is Necrophorus investigator (but there are many very similar ones and some even quite different. Watch out for them this autumn as they fly across the deep night skies.

 

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:

Jackdaws at their chimney nest - it's almost impossible to differentiate the male from the female but she is usually slightly smaller, making her the one with the bread in its beak.

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.
