Bountiful Bynea

I had intended this morning to access the saltmarshes between WWT Penclacwydd and Machynys to see what I could find, thinking that I`d also make a quick prior visit to the brownfield habitat behind some industrial premises at the easternmost end of Bynea, at the very south-eastern edge of Carmarthenshire.
Along the informal path that literally skirts the edge of the estuary at Bynea a lot of amenity planting of trees has been undertaken in the past and  having noticed field maples here previously, I made a mental note (which I duly forgot!) to re-visit in the early autumn. Seeing the field maples there today - and thus remembering about their presence!- I started searching for E. louisella leaf-mines but, after about half-a-dozen trees, gave up. Later, I stopped by another tree and there it was...

Above: Loughor Bridge linking Carmarthenshire and Glamorgan. I was tempted to have a furtive `lurk around` in vc41 but if Barry Stewart, the local Marcher lord, caught me it would mean a long spell in the Glamorgan gulag. The leaves framing this photo are those of the very field maple on which I found louisella.

I also found Caloptilia semifasciata on other field maple leaves. Photo below:

Moving on along the estuary-edge track, I reached the brownfield site, looking parched after the recent dry weather.
            Above: the `Bynea Serengeti`, a mix of dry grassland and birch/willow scrub.
 Above: In the scrubby area was the ubiquitous Lyonetia clerkella on birch; note the really well-segmented larva to the right.
 Above: on apple, also in the scrub area,  this may be Bohemannia pulverosella; the dark bits are frass.
Above: as with the last one, I`m uncertain about this mine - note the distinctive round blotch as well as the broad mine to its left. Suggestions welcome, either on the blog or via email.

Within the willow/birch scrub area, I checked for lunar hornet clearwings, which are known locally in the Bynea-Llwynhendy area, but had no luck. However, when searching the bases of the old willows I became aware of small moths being flushed off the trunks, flying briefly before settling nearby on the same tree.
               Above: the old willows and one of the `small moths` - Batrachedra praeangusta.

Finally, due to the heat and spending more time than anticipated at Bynea, I decided to leave the sunny saltmarshes for a cooler day (or better still, a warm evening) and instead opted for a short inspection of a nearby locality - Morfa Berwig LNR.
Briefly, the highlight here were a couple of adult and large metallic-shining Coleophora trifolii, noted atop tall/ribbed melilot patches. I netted one twice, but both times it escaped.

  1. Good work Ian, some nice records there. I've walked the same path to see the rare Scopelophila moss that Marcher lord Barry found there.
