The Winter Solstice occurred at 10.44 am GMT this morning, which is our local time in Ireland, but there probably won’t be a noticeable lengthening of the day until 25 December, Christmas Day. This is the deepest point of the greater winter, the time exactly halfway between the Autumn Equinox and the Spring (Vernal) Equinox. According to the ancient Celtic calendar this was also the centre of true winter, halfway between Martinmas and St. Brigid’s Day. But in the modern world it is only the start of Astronomical Winter, which ends on the Vernal Equinox in late March. And the weather generally matches the astronomical seasons, with proper winter cold not getting going until now although the days are growing longer.
At this time of year some wildlife is hard to see, some is completely hidden, some not so obvious. But some wildlife is easier to see, especially birdlife as many birds come into gardens looking for food. Some insects species only appear at this time of year, such as the moths in the previous post, and here’s yet another handsome one, the Scarce Umber – Agriopis aurantiaria.
This might be the last Scarce Umber to be seen this year, as they only fly from October to December, and are therefore a true autumn moth. And, as is the case with many moths in autumn and winter, only the male has wings. The female is a strange-looking wingless insect.
Also keep an eye out for late autumn fungi. There are some spectacular Common Inkcap – Coprinopsis atrametaria – about, usually along roadsides in small groups at the bottom of earthen banks or ditches, as was the case with these ones:
