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.

 

 

April Transformation

We had a very cold and somewhat wet March, and April has been somewhat similar, bright and sunny but often windy and chilly at the very same time. However, a huge change is underway and spring is unfolding by the day and the hour. Only a few days ago I was delighted to see a queen Carder Bee (Bombus pascuorum) sunbathing on some bare ground among the violets.

A furry queen Carder Bee, which usually appears later in spring than the much larger Buff-tailed Bumblebee queens. This is very much the spring bumblebee.

Particularly delightful is the sight of Tawny Mining Bees (Andrena fulva) on the wing.  Usually males appear first, but this year I spotted a big furry female days before the first male. This is officially our rarest species of solitary bee, and as a result the National Biodiversity Data Centre are looking for recorded sightings from the public.  Here is a link to the record sheet, which is easy to follow and make submissions on: http://records.biodiversityireland.ie/submit_records.php?fk=SolitaryBeesStandard&caching=cache

And here is a photo I got two days ago of a female Tawny Mining Bee:

There is a similar but smaller species of mining bee also appearing right now, the Early Mining Bee (Andrena haemorrhoa). The males are very similar to the Tawny Mining Bee males, but much smaller and lack the white beard. The female is very beautiful, and here is a photo of a female from the same day as the Tawny Mining Bee photos:

A pretty female Early Mining Bee. She is much smaller then the female Tawny Mining Bee, and about the size of a male of that species.

Also buzzing around the lawn, feeding on dandelion flowerheads is a small and somewhat sinister-looking wasp. This is in fact yet another bee, but for the mining bees it is indeed sinister, as it’s a parasitic bee which lays its eggs in the nests of mining bees, its grubs killing and eating the mining bee grubs. This particular species of cuckoo bee is Panzer’s Nomada (Nomada panzeri):

But it hasn’t all been bees. Despite the cold some sunny days have warmed up sheltered areas enough for migrating butterfly species to begin flying about. So far I have only seen two butterfly species, and this one is the second, a Peacock (Inachis io):

Goodbye July!

Unfortunately this year we had a somewhat cool and overcast July. This has been due to the peculiarities of the weather system which has seen weeks of rain clouds crossing the Atlantic to arrive on top of Ireland. However, there has still been some wildlife to see, and for this instalment I want to share some videos I made. Here is video of a Red Kite, which is a species which was deliberately reintroduced to Ireland, with Wicklow as the focus point:

Red Kites are mainly scavengers, and are huge birds, but will happily take prey too, especially small rabbits. They are the only large bird in Europe with a forked tail.

Now here’s something a little different from the micro jungle, a Zebra Jumping Spider with a woolly aphid as prey. It takes a moment to get the focus exactly right but it does make for an interesting scene:

Also from the microcosm, here’s a little moth you will commonly see feeding on flowers during daylight hours in summer, the Nettle-tap Moth. They are very curious little moths:

Now is the time to see spiderlings emerging, and the most spectacular are those of the orb-weaver spiders. There are several species and they can be hard to tell apart when they’re so young, but I think these in the video below belong to the Segmented Orb-weaver, but there is also a small chance they are Garden Spiders:

But just because you see web tents it doesn’t mean they were made by spiders. Many insects also spin webs, especially caterpillars of butterflies and moths. Check out the incredible web-tents of these beautiful and very numerous Peacock butterfly caterpillars. They feed on nettles exclusively, which is why they are popular with many people. Peacock butterflies also hibernate:

Finally, if you are in Wicklow at this time of year take a look into the shallow streams and you will almost certainly see Brown Trout. In summer they are very numerous in the streams but are not always a guaranteed sighting as they migrate around rivers from shallower to deeper waters and vice versa depending on the time of year.
