Carmarthenshire Moth List update

After adding the 2016 records to the database I produced a revised moth list for Carmarthenshire, including categories A (all records please), B (photo needed for new site records) and C (photo needed for all records), the number of records of each species (an indication of what's common and what's rare), and the year of the last record (again, an indication of what's rare).  Please have a look at this, as it's a guide to what species of Macro are going to need extra verification.

Thanks Colin for adding it to the Resources section on the right hand side of the Blog.


  1. Marvelous job, Sam - thanks very much and very well done. Much appreciated. This confused old fool would be most grateful if you could explain the colour code used throughout and the letters D P & R against some micros. Have you been able to re-assess some of the old Rothamsted records: some species previously thought to be scarce seem to have had quite large increases in numbers in the last two or three years?

  2. Yes, thank you Sam once more - we all really appreciate your efforts and skills.
    I`m hoping to start the macro-moth write up for 2016 in about 10-14 days` time, to add to Sam`s (already 99% done) micro/migrant review etc, so that we can get the newsletter out in mid March.

  3. The colours indicate number of records and oldest last records: you need to think carefully if you think you've got a red or orange! The letters were my start at marking Dissection only micros, but I can't remember whether I finished that exercise.

  4. And yes, adding the compete (and very obviously correct except for a couple of dodgy sites) Rothamstead data boosted the number of records of upland species, especially as Rothamstead sent their complete data whereas previously I only had annual summaries.

    1. Thanks, Sam. I'm sure that Jon B was right to be wary of the Rothamsted data as presented to him, but it's very good to know that some difficult issues have been resolved satisfactorily. We can at last see that some species previously thought to be rare, or uncommon, in Carms are more likely to be simply local in their distribution and not too scarce at all. Autumn Green Carpet is a clear example of this and I'm sure there are many more. Once more, we should all be grateful for your efforts in resolving the Rothamsted conundrum.
