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.
This year we have had a very cold spring, and most plants and wildflowers are way behind their normal growth levels, but yet again the humble and resilient Dandelion (Taraxacum officinale)has saved the day.
Dandelions can flower all year, but in April they absolutely explode into blooming and our environment and our food depends on the fact that the massive amounts of pollen produced by the dandelion blooming sustain vital pollinating insects at a time that would otherwise be a crisis for them, and then result in a crisis for us. In fact, I believe we should have a dandelion festival every year to celebrate this most important of all spring wildflowers. This is my video dedicated to the dandelion:
Above is one of our rarest pollinators, the Tawny Mining Bee (Andrena fulva) and this species also depends heavily on the dandelion for pollen, especially as this bee emerges in late March and flies mostly in April, and to a lesser degree in May, before dying off by early June and not being seen again until the following spring.
However, big bumblebees depend on them too, like this huge Buff-tailed Bumblebee (Bombus terrestris). Let’s celebrate the dandelions. They deserve it.
Winter has been very long and drawn out, but at last the weather seems to be improving and very gradually warming up. Late last night I was delighted to find two spring moths on a wall by a window. The first is the old reliable still lacking a common name, Diurnea fagella:
Slightly more impressive than this drab but variable moth was the stockier, and more handsomely marked Common Quaker (Orthosia cerasi):
This medium-sized (small medium) moth had a small chunk taken out of its left forewing, which was very possibly due to a nip from a bird’s beak. The recent more consistent temperatures have caused spring flowers to bloom in a big way, and the annual mass flowering of dandelions is now beginning. Dandelions are extremely important for pollinators, and many other insects, as are the Lesser Celandine flowers. You can see one here being attended to by a Honey Bee (Apis mellifera).
However, today I saw something which really lifted my spirits, my first butterfly of the year, a Small Tortoiseshell (Aglais urticae):
And I even made a video about it, and it’s not as bad as it first seems:
