Lichen: Ramalina fastigiata

British lichen, lichen on trees, Ramalina fastigiata, trumpet-shaped lichen

I’ve seen this lichen described as a fanfare of trumpets, which is just the most perfect description for a lichen that can be found adorning the branches and trunks of trees throughout the year almost everywhere in Britain. Meet Ramalina fastigiata.

Flowers and catkins

On most of the Hazels I’ve checked, the male catkins look almost fully formed but are still tightly closed and the female flowers are mere buds but, during Friday’s meander, I found one Hazel that’s ahead of the rest in its development. The male catkins were open and shedding cloud-like bursts of yellow pollen when the wind caught them, and the tiny crimson-pink female flowers, looking for all the world like miniscule sea anemones, were open and receptive. Hazel nuts in the making!

On narrow-leaved willows

In early October I, and others, began a new leafmine search, for mines on narrow-leaved willows (see Leafmines: Phyllocnistis saligna, 3 October). In the months since, I’ve only found these mines in two locations, partly due to a lack of the host plants and partly, probably, because the moths have yet to spread very far (which may be because of a lack of host plants). I’ll continue the search next autumn but, in the course of my search – and this is one of the brilliant things about staring at leaves – I’ve found many other life forms that were making these leaves their home.

I found two types of galls: the first, above top, have been made by a species of mite, Aculus tetanothrix, and those immediately above are home to the larvae of the sawfly species, Euura proxima.

On the underside of one leaf I found this array of what I think are moth eggs and, on the right, is the pupa of a ladybird, and, below those, is a hoverfly larva.

There was also a different species of leafminer, the tiny moth Phyllonorycter viminiella, and I found a rust, which might be Melampsora caprearum.

Flowers and berries

Holly, Holly berries, Holly flowers

There seems to me no better example of our changing climate and the confusion it’s causing in the natural world than this: finding one Holly tree in flower and others carrying berries all at the same time. In fact, the photo of the flowers, which are supposed to bloom during the spring and early summer, was taken at the beginning of this month, two weeks after that of the berries.

Beautiful Beeches

autumn colour, autumn trees, beech woodland, Cwm George, winter woodland

I’ve shown you this beautiful location several times before – this is Cwm George, in the small south Wales town of Dinas Powys – but I simply can’t resist sharing this year’s late autumn splendour. I couldn’t decide which view I liked best, so I’ve included three images, each one zooming in to the scene a little further. I hope you have somewhere magical like this to enjoy, to wander through, to escape into.

Leafmines: Bucculatrix ulmella

British leafminers, Bucculatrix ulmella, cocoon on Oak leaf, leaf-mining moth, leafmining moth larvae, moth cocoon

This new-to-me species was the result of a recent session turning over Oak leaves to see what might be lurking beneath. I didn’t actually find the leafmines for this creature but rather, on adjacent trees, two empty cocoons – the tiny moths (pictured on the UK Moths website) that were metamorphosing inside had already hatched and flown (you can see part of the pupal case poking out of one cocoon). The ribbing on the cocoon points to this being one of Bucculatrix genus of moths and the fact that these were on Oak gives a positive identification of Bucculatrix ulmella (don’t be fooled by the specific name ulmella, which would appear to indicate the larvae feed on Elm – the species has apparently been misnamed).

Leafmines: Stigmella obliquella

As part of my continuing search for the leafmines of the moth Phyllocnistis saligna, I spent part of a recent walk checking the narrow-leaved willows in a Cardiff Park. Though most of the leaves had already fallen, I noticed a lot of leaves with ‘green islands‘, a likely sign of a leafminer but probably not the one I was looking for and, indeed, not one I was familiar with. I took some photos and posted a selection that evening on Twitter.

Leafminerman Rob Edmunds, of the superb British Leafminers website, quickly identified them as the ‘very variable’ work of the larvae of the moth Stigmella obliquella, also known as the Willow pygmy, a rather cute micro moth with an orange top knot. You can find out more about the leafmines on the British Leafminers website, and see the adult moth on the UK Moths website; just click on the links.

autumn colour, autumn leaves, autumn trees

As today is the last Sunday of autumn  I thought I’d pull together a little video of this year’s display of trees and their leaves, from the brown and bland to the rosy red and spectacular. Come scuff some leaves with me …

‘Autumn leaves don’t fall, they fly. They take their time and wander on this their only chance to soar. Reflecting sunlight, they swirled and sailed and fluttered on the wind drafts.’ ~ from Where the crawdads sing, Delia Owens, G. P. Putnam’s Sons, New York, 2018

Leafmines: Phyllocnistis saligna

A new month, a new leafmine challenge, and it’s got off to a very successful start for me. But let’s start at the beginning …
Our locally based Senior ecologist with Butterfly Conservation, George, kickstarted the challenge with a couple of tweets and some photos last Friday evening:

Ok #TeamLeafmine here’s another recent S. Wales colonist to look for; an easy one to identify too. Phyllocnistis saligna mines narrow-leaved willows, unusual because it mines both leaves & young stems. 3 recent records by the Taff in North Cardiff, must be out there elsewhere!

Cocoons are formed in a turned over leaf edge, see 3rd photo in original tweet. Quite a few Gwent records from the Levels and Monmouth/Abergavenny, also new to Carmarthenshire in 2021. Must be in & around Cardiff Bay! More info here: http://leafmines.co.uk/html/Lepidoptera/P.saligna.htm

I didn’t have any firm plans for Saturday’s walk so wended my merry way along the edges of the two local rivers, the Ely and the Taff. I soon realised that this challenge will be a little more difficult than previous ones, as narrow-leaved willows were few and far between and, when found, often inaccessible. However, I did manage to find mines in two locations along the River Taff, which has encouraged me to continue my search further up the river very soon. And, though I hope to find more mines, I doubt I’ll find one of the very lovely little adult Phyllocnistis saligna moths, the wonderfully named Willow bent-wings, which you can see on the UK Moths website.
