Dandelion Time

Up until last week it was still quite cold, but finally the weather has improved and at last we are getting proper warm spring weather. It’s that special time of year, the height of the great spring dandelion blooming. Dandelions support the vast majority of pollen-feeding and pollinating insects to a degree impossible to any other spring flowers. It’s great to see these important plants are finally starting to get the recognition they deserve:

They are beautiful flowers too, and give us a bright yellow landscape. Other flowers are starting to reach their full bloom too – here, for example, are Bluebells, the true wild bluebell which is quite common in Wicklow and possesses a beautiful scent, unlike the similar-looking Spanish Bluebell:

That butterfly is a Peacock (Inachis io) and it soon gave up the bluebells to feed on dandelions again.

This is also the time when the cherry trees are candyfloss pink from blossom, and they really do brighten the place up a good bit:

However, as beautiful as it is, it’s also important to remember spring is a time of high drama. At the moment you have a good chance of seeing the rare Tawny Mining Bee, which I mentioned in the last post. The male bees have now passed on, and the females are pregnant and busily constructing their nests, which are burrows. The mouth of each burrow is surrounded by a mound of soil, sometimes quite a lot. Tawny Mining Bees are parasitised by Cuckoo Bees, such as Nomada panzeri. They lay their eggs in the nests of the Tawny Mining Bees, and their young feed on the larvae of the mining bees. Here is a Cuckoo Bee, in the foreground, watching for an opportunity to get into the nest of a Tawny Mining Bee, but the owner is watching from the entrance:

As I tried to get a closer photo I accidentally scared the Cuckoo Bee off, and the Tawny Mining Bee decided it was safe to emerge:

These bees are usually gone by May, so now is the time to look for them. Next year’s generation will soon be hidden underground awaiting their time to fly in the sunshine.

 

St. Patrick’s Day and the start of true Spring

Because the St. Patrick’s Day parade in Greystones yesterday was so spectacular, and large, and blessed by sunny weather, I opted to upload that video on its own, and devote a second video to my annual St. Patrick’s Day nature walk. This year’s was far less dramatic, but far more beautiful, although the weather did get interesting later in the day, with showers of freezing rain and hailstones. So here is the video, but read on after it too:

Whereas last year it snowed the day after St. Patrick’s Day, today something more welcome occurred – I found my first Tawny Mining Bee of the season, and it was a female, the earliest female of this species I’ve ever found. She appears at the end of the video too, but here’s a close-up shot of this very beautiful bee:

St. Patrick’s Day is traditionally held on the anniversary of St. Patrick’s death. However, in ancient times 17th March was a very important feast day, that of the god of fertility, Bacchus, aka Dionysius, marking the arrival of true Spring. Because astronomical spring in Ireland also marks the arrival of warmer spring weather. This coming Wednesday, 20th March, is the Equinox. At 9.58 in the evening the earth is exactly halfway on it’s journey around the Sun, and day and night are of equal length and the Sun rises directly in the east and sets directly in the west. From that day on, until the Summer Solstice in June, the days get progressively longer than the nights. Exciting.

 

April Adventures

Spring has been a little slow to take off – I only saw my first Swallow yesterday, and we only had our first reasonably warm and sunny weather over the last three days. There might not be swallows but the sunny weather has brought out some very impressive birds, most notably Buzzards (Buteo buteo). These birds are best described as either very large hawks or small eagles and should not be confused with vultures which are a very different kind of bird. Here are two photos I got of one bird recently:

Buzzards like bright, sunny days because they can use the sun to hide their approach. Their favourite prey are rabbits, especially in spring when there are abundant young rabbits around which lack the experience of older rabbits and can be easily caught. Buzzards will also eat rats and will scavenge roadkill. The famous cry of the hawk in American western movies is the same as the cry of the Buzzard.

Because it’s April I would like to remind you to keep an eye out for Ireland’s rarest known species of solitary bee, the Tawny Mining Bee (Andrena fulva). These bees make small volcano-like burrows on lawns and the female is stunningly beautiful. They have no sting and although you might see a number of bees in one area they are not working together as a colony but living single lives. Here is a photo of a female, and the yellow on her hind legs is not the bees colour but, in fact, pollen collected on special hairs:

The male is much less handsome and harder to tell apart from the males of other mining bee species, of which there are a few in Ireland. And here is a photo of a female in her mine. They often like to watch from the entrance and will duck their heads in if they think they’ve been spotted.

The female is about the size of a small worker bumblebee, but is large as mining bees go. There is a very similar bee species which is more common and not quite so red in colour, the Common Carder Bee (Bombus pascuorum) which is more robust-looking, and I here is a photo of that species so you can tell them apart:

If you see a Tawny Mining Bee and especially if you find nests the National Biodiversity Data Centre will want to hear from you, and they can be contacted at this website which allows you to submit records, coordinates and photographs of anything and everything in the natural world, but rare creatures especially:
