We’ve had a very cold wet autumn and now a good chilly winter has arrived. Today is Christmas Day and we had a superb bright and sunny morning due to cool, clear skies. There was a good frost this morning. Here is a video I made of bees feeding on blooming mahonia. Mostly they are the hardy White-tailed Bumblebee, Bombus lucorum, with some very big examples. This bee commonly flies in winter. But there was also one Honey Bee in there, Apis mellifera.
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.
It has been the most protracted cold spring in living memory, and as a result butterflies have been extremely slow to appear, as they need 15° Celsius in which to fly, and it was much less than that up until last week. In fact, we had daytime temperatures as low as 6° Celsius! But this week temperatures leaped up to what would be normal for this time of year, and even above that, and suddenly butterflies and spring moths were appearing as if by magic. Here is one which I was very surprised to see, the Comma (Polygonia c-album):
Most surprising of all has been the numbers of Peacock butterflies (Inachis io) which have appeared in only the last three days. They are big and bold wine red butterflies with dramatic eye-spots:
Here’s a male Orange-tip butterfly (Anthocharis cardamines) which had hatched out from a chrysalis,perched on some garden netting and waiting for its wings to expand and stiffen. This one is a male, as you can tell from the orange tips visible at the top of its fore-wings:
The butterflies of spring are here, but that’s not all – so too are the moths…
