The last dragon

Though I’m still hoping to spot another damselfly species, the Migrant hawker (Aeshna mixta) is probably the last of the larger dragonfly species I’ll see this year. I’ve spent many an enjoyable minute or ten watching these beauties flying back and forth along the edges of woodland rides and local pathways, waiting hopefully for them to perch, only to have them fly above the trees and disappear, or stop in a place too distant for photographs. So, I was especially grateful when this hawker proved to be much more cooperative.

By the sea

#WildflowerHour, British wildflowers, Echium vulgare, seaside wildflowers, Silene latifolia, Tanacetum vulgare, Tansy, Teucrium scorodonia, Viper's-bugloss, White campion, Wood sage

This week’s challenge for #WildflowerHour was ‘What can you find blooming along the coast?’. I’ve had a couple of walks around parts of Cardiff Bay this week and could’ve included a lot of plants but have selected just four.

230820 vipers-bugloss

As Cardiff Council has (amazingly!) refrained from cutting the Barrage grass in recent months, the few Viper’s-bugloss (Echium vulgare) plants that were previously growing there have increased markedly. There must be over 50 plants now spread across the expanse of the Barrage, and the blue flowers make a lovely contrast against the grass green.

230820 tansy

I rarely see Tansy (Tanacetum vulgare), so this single plant, thriving on the sandy slope below the children’s playground on the Barrage, was a delightful surprise.

230820 white campion

Growing just along from that Tansy plant, was this lone White campion (Silene latifolia) plant. It wasn’t looking as healthy as the Tansy but was covered in seed heads so I think it was just past its best.

230820 wood sage

This Wood sage (Teucrium scorodonia) was a total surprise as you wouldn’t necessarily expect a plant with ‘wood’ in its name to be growing alongside a seaside path. My book says it prefers acid soils but, when I googled, I found many examples of Wood sage growing on scree slopes, amongst limestone, and close to sand dunes, so I guess it’s very adaptable.

The passing of the Tree pipits

Tree pipits have been heading south in their ones and twos for a couple of weeks already but on Wednesday, with fine weather and a light easterly breeze, their flow increased noticeably. A local birder clocked over a hundred in the hour he watched that morning; another, whose patch is Kenfig NNR, reported a count of 53 during his morning visit; and I noticed similar reports from many locations on social media. Migration magic!

Hygrocybe acutoconica

Here’s another sign that autumn’s come early this year. In previous years I’ve not seen these waxcaps in my area until very late September, mostly during October, but this year they’re fruiting now, at least a month earlier than usual.

230818 Hygrocybe acutoconica (1)

These are Persistent waxcaps (Hygrocybe acutoconica). At first glance, with their conical caps and yellow-orange colour, they look very similar to Blackening waxcaps (Hygrocybe conica) but these don’t blacken. Persistents are the only waxcaps I find locally so it’s always a pleasure to see them, even if it does mean an early autumn.

This gorgeous creature could be found clinging to the outside of my bedroom window all day Tuesday, in the wind and rain during the morning but, when this photo was taken, enjoying the evening sunshine. I think this is the cranefly, Tipula paludosa.

The mystery of the white thistles

bacteria on Creeping thistle, Creeping thistle, Pseudomonas syringae, white shoots on Creeping thistle

I’ve noticed in previous years that the top shoots of many Creeping Thistle plants (Cirsium arvense) sometimes turn white at this time of year and I’ve only recently found out that this is caused by Pseudomonas syringae, a bacteria that produces a chemical called tagetitoxin, which poison chloroplasts and causes chlorosis.

230816 white thistle (1)

There’s an excellent article on the Llanelli Naturalists website, entitled ‘The Mystery of the “White” Thistles’, which includes the following explanatory paragraph (nb this article was uploaded in January 2009 so the situation has probably changed since it was written).

This bacterial disease was recorded in the UK for the first time by a retired plant pathologist, Dr John Fletcher, in the vicinity of his home in Canterbury, Kent, only six years ago. The bacterium causing the disease is now thought to be a pathological variety of Pseudomonas syringiae – a complex of bacterial types that affects over 180 species of fruit, vegetable, forage and horticultural plants. The infection on creeping thistle was found for the first time in Canada in 2003. Scientists from Alberta (Zhang et al, 2004) recorded the disease at several locations across Canada and have named it the “White‐colour disease of Canadian Thistle”. Their diseased plants showed apical chlorosis and these symptoms were associated with stunted growth, fewer shoots, inhibition of flowering and/or sterility. These are exactly the same symptoms found on the local populations of Creeping Thistle at Burry Port.

That tongue!

#MothsMatter, British moths, Hummingbird hawk-moth, moth, Red valerian

In a recent post (Moths matter, 4 August), I included photographs of a stationary Hummingbird hawk-moth that had flown past me before going to ground on the path in front of me. This week, during a walk along the embankment footpath where the River Ely flows in to Cardiff Bay, I watched spellbound as another of these magical moths hovered, feeding from Red valerian flowers, right in front me. I took rather a lot of photos, clicking almost continuously, hoping I was getting some in focus. This, I think, is the best of those images, and one I’m very pleased with. And, yes, that tongue!

A surprise Silver-washed fritillary

British butterflies, butterfly, fritillaries, Silver-washed fritillary

I’d seen a second generation Dingy skipper; got close enough to a migrating Redstart for some reasonable photos; watched Whin- and Stonechats and a Tree pipit insect-catching in the tree plantation; spotted my first Migrant hawker of the year; and was just heading in to the woodland, hot and homeward bound, feeling very pleased with what the day’s walk had turned up, when this happened.

As if materialising from thin air, this Silver-washed fritillary floated along the path beside me, before settling on the ground almost at my feet. I was amazed! Singles of these butterflies have very occasionally been spotted in Cosmeston’s Cogan Wood but never before by me, despite my having walked every inch of the various paths that thread their way through the trees. It was the perfect end to a perfect day in Nature!

An interlude of orchids

When I first spotted these Broad-leaved helleborines sprouting back in June, I despaired for their survival in the dry heat. But several weeks of intermittent rain have brought them back to life, and they look as beautiful as ever.

A slim Spotted flycatcher

I couldn’t help but wonder if this Spotted flycatcher was looking so slim because of a shortage of insects during the last couple of months. Though the abundance of tiny critters has improved a little now, I’m sure those earlier lifeless months will have affected both adult birds trying to feed their youngsters and the growth – or even the very survival – of those youngsters. (And, yes, that’s a cheeky Whinchat poking its head in at the left of the photo – we’ve been lucky to have both Whinchats and Stonechats visiting the outer fields at Cosmeston Lakes Country Park.)
