Thanks Andy, I am learning



Thanks Andy,
I am learning all the time.
May not be a moth but still very interesting.
The shape and markings do look like Limnephilidae.
I have added three more photographs.
I was looking at the NBN Gateway and Trichoptera Limnephilidae seems to be very well reported in Scotland but very patchy in England
caddisflies and NBN
Les,
Although the NBN Gateway maps are a fantastic resource, they sometimes need a bit of interpretation. Are you looking at this one for Limnephilidae?:

If so, I think what is happening here is that it is only showing those records that have been assigned to "Limnephilidae" as a family, i.e. not records of all the species within the Limnephilidae. And since the list of datasets includes one from the "Scottish Environment Protection Agency" I would guess that they carry out river surveys in which caddis are recorded at family level rather than species.
The Limnephilidae map doesn't include any data from the national caddisfly recording scheme, and I think that will be because the recording scheme only uses records of species rather than families. The recording scheme is at:
http://www.brc.ac.uk/schemes/RRS/trichoptera.htm
The only comprehensive key to caddis relies heavily on details of the structure of the genitalia, which can usually be examined at the tip of the abdomen without dissection, but can't be seen in a photo as the wings get in the way! I don't know caddis well enough to suggest a species from the photos I'm afraid, but perhaps someone else will be able to.

I agree with all the helpful comments you have recieved so far. Once you get your eye in for the distinctive stance of a caddis and the hairy wings then you will be there.
This is an abundant species. I am workng on a new batch of cadis records for the NBN , about 200,000 and the map for this species will reflect its occurrence, when I subkit the data in a few months time.
However, common as it is, it is a very attractive little beast, and all records are useful for the recording scheme and its users.

Often confused
These are often mistaken for micro-moths as they come to light traps. However, they have hairs on the wings hence Trichoptera = hairy winged as opposed to Lepidoptera = scaly winged.
