On the mountain.
The Afon Cennen, that babbling brook that passes so scenically beneath Castell Carreg Cennen's stern gaze, begins its journey high up in the peat bogs of Y Mynydd Du to the north-east of the Tair Carn ridge. It plunges steeply down the northern scarp slope, but cannot be seen, for it flows beneath boulders in the massive ravine that it made at the end of the last ice age, perhaps 10,000 years ago. It was in that ravine that I determined to place my tiny actinic trap last night.
The last time I tried trapping here was in late March; it was quite warm in the valley, but I soon found that this was not the case up high. I sat with the trap as the wind increased and whistled up the ravine and the temperature dropped to near freezing. I packed up at midnight, having captured one moth (a Red Chestnut) and struggled back down the ravine and home to Cwmllwyd.
Last night, however, was rather more fruitful. I climbed up the mountain in daylight, setting up the trap at about 1400 feet, checked that the sensor was functioning and would light the trap at dusk and went home. This meant that I had to be up and away up the mountain again at dawn, easier this time without the weight of the kit. Was it worth it? Well, I hope you will agree that it was. 15 species put in an appearance and I think that some of these are worth showing below.
