Mynydd Llangyndeyrn - daytime mothing.
About twenty years ago, Neil Matthew recorded the forester at this site and I was certainly keeping vigilant in the hope of seeing this day-flying moth, especially after Vaughn`s sighting at Salem a few days ago.
I flushed one only, in a block of limestone grassland just west of Clos yr ynn, where common sorrel Rumex acetosa grew with some frequency. At first, for a second or so, I `d thought it was one of the common blues that were around, but the very bright iridescent blue-green and the strange, almost pulsatory flight made me quickly realise that it was a forester.
On the first two general photos of this blog, the related sheep`s sorrel Rumex acetosella can also be seen - again as brownish-red plants - on the rocky heath areas.
Another interesting moth found on the limestone area of Mynydd Llangyndeyrn (the bulk of the ridge being acidic Millstone Grit quartzite) was Britain`s smallest longhorn - Adela fibulella which can be found on germander speedwell flowers. I`ve had it on Mynydd Llangyndeyrn before and so has Sam Bosanquet.
Other moths seen include a mother shipton and a nice banded form of a mottled beauty.
I also visited the limestone pavement area of Carreg Eidon (the `bullock`s rock`) and was rather dismayed to see that it has not been managed appropriately (Mynydd Llangyndeyrn is SSSI), and with serious scrub invasion. Latterly, the ex-CCW have done an excellent job with the main commonland area of the site, but the pavement area is in really poor condition and requires scrub removal and grazing.
