Hi Spacemouses and WLR, The

Hi Spacemouses and WLR,

The wing markings are quite a close match for Limnephilus subcentralis in Barnard and Ross 2012 but the size and location would fit better for L. borealis.

The example of borealis given in the book just isnt as close in appearance as their example of subcentralis but subcentralis has a forewing length of 11-14mm and is given a specific location of central Scotland, not common. The location and size of 22mm certainly point towards borealis but?....

I shall have a closer look at

I shall have a closer look at these if I get anymore in trap (weather permitting!).

As this is from such a way

As this is from such a way out place it would be marvellous to say it was not just lunatus and actually I now think it is one of the subcentralis or borealis pair but which one. All the subcentralis I have seen have been dead a long time but more gingery but boralis has also been more darkly marked. So it either a pale borealis or a dark subcentralis or a really weird lunatus.

Need a dead one to look a its genitalia

Hi Ian, I think I should

Hi Ian,

I think I should collect some samples next year on some hill loughs in my locality in NE Co. Antrim. To cut a long story short, I am either seeing quite a variation in lunatus or I am seeing lunatus and other species. I find insects just like the above.

The only way to understand the variations I see is to have them properly examined. I would be grateful for any advice on who can do a proper examination on some samples?

They may well all turn out to be lunatus but its worth investigating due to the diversity of appearance and size.

Maybe I will keep a few next

Maybe I will keep a few next year if anyone wants to examine them. This has been extremely bad year for such things in this part of the world.

Hi Ian,

To cut a long story short, I am either seeing quite a variation in lunatus or I am seeing lunatus and other species. I find insects just like David's one above- quite sandy brown in appearance with a small lunar crescent and no black edge to it.

Hi David, Ive just noticed

Hi David,

Ive just noticed my duplicated comments above, I dont know how that happened.

Hebrides borealis record

You will notice that I have wobbled over naming this one as anything other than lunatus is a new record for the Hebrides.

I have at last decided to cone off the fence and add this to the national data base but with a note that a vocuher or at east someone looking at the genitalia of another is needed to be absolutely sure. That way a possible very interesting find is not lost to the system as just another lunatus.

I have not sampled the Hebrides but from general descriptions then borealis is more likely than subcentralis and it is nearby on the mainlabnd.
