Cors Fochno

The weather was rather wet when we went to check the traps this morning. The numbers were a bit disappointing but we did have 2 Rosy Marsh Moth. Of the other 20 macro species the most numerous were True Lover's Knot and Large Yellow Underwing. Amongst the rest were Canary-shouldered Thorn, Yellow-barred Brindle, Scarce Footman, Pinion-streaked Snout, Garden Tiger, Chevron, Willow Beauty, Coxcomb Prominent, and Barred Rivulet.

  1. Barred rivulet not in your document Tony. I'm a bit puzzled that you catch these on Fochno as red bartsia and eyebright aren't typical peat bog plants. Should we be catching it elsewhere?

    1. Sorry, I somehow managed to lose the Barred Rivulet page when I produced the final document. This will be corrected as soon as possible but contact me if you would like a copy of that page.
      This is quite a rare moth in Ceredigion. Up to the end of 2016 there have been 58 records, 10 of which are from Cors Fochno and 13 from the Tregaron area. It may be under-recorded since Red Bartsia is frequent in the county in pastures, pathsides, road verges, railway ballast, quarries and waste ground according to the "Flora of Cardiganshire".

  2. Red Bartsia occurs in a number of places on the Cors fochno where the peat is deep but has been modified by drainage and agriculture. It seems to like horse or cattle grazed acid swords where waterlogging isn't too great.
