Hi all,walking through some Beech woodland near Stoodley Glen,i flushed a brownish carpet type moth which landed on a beech trunk,i got a good look at it,but made the mistake of trying to get a pic on the tree where settled !! and youve guessed it off it went !! thinking of seeing if can get a light in the area hopefully one night.not sure if it was 1st/2nd generation,though it looked quite nicely marked.Bri.
