More on fog

I was very interested in Steve's fog experiment and Heathrowish conclusions (Dave can no doubt speak from professional experience on this). Inspired by his post, I put the trap out last night when the fog was as clammy as felltop mist.

The result this morning, for possible interest to fog/moth surveyors was: Large Wainscot (3 - sorry, Dave; I keep pointing them in the direction of the A34)), Red Green Carpet (3 or poss 2 depending on the kindly experts' view of my pics here), Autumn Green Carpet (poss 1, depending similarly), Red-line Quaker (2), December moth (2), Setaceaous Hebrew Character (2), Yellow-line Quaker (1), Sprawler (1), Winter/Autumnal/etc moth (1), Feathered Thorn (1) and Angle Shades (1).  I'd be very grateful for a decision on the three Carpets shown here; I am assuming all Red-green but wondered if the last might be AGC.  Martin Wainwright, Thrupp, Oxon


  1. Hello Martin, sadly I have no personal experience of Autumn Green Carpet but I'm sure your pictures do all show Red-green Carpet, even the seemingly red-less one which is quite a frequent form.

    It was very foggy here too last night when I turned on the garden trap but within an hour or so the breeze had picked up and for the most part dispersed it, the temperature rising too, so I ended with quite a reasonable collection (19 species, not bad for November).

  2. I did suspect that other fog experiments might contradict my results, although the fog here on Sunday night did hang around all night with not a breath of wind. On the basis that planes seem to be flying over my garden again today, I shall put out tonight's GMS trap with renewed optimism.

  3. Hi Steve - I think Dave's comment helps explain my catch as the fog maybe thinned, though there was still plenty around in the morning. Interesting experiment - thanks for getting it going. All v best M
