I have come across an interesting article in an old (Summer 2008) copy of The Grayling Journal
which I think I have attached. In it he states that "In May and June there is a very important emergence of small grey caddisflies from the family
Glossosomatidae,the two most common species that appear on Trout and Grayling waters are
Agapetus fuscipes and
Agapetus ochripes. These are proving to be very interesting and drive fish mad on the edge of dark when they emerge."
I recall somwhere Ben mentioning small grey caddis emerging in the evening and having great sport when this occured. This could be this emergence I suppose. What did you catch on Ben,size and dressing?
As Stuart has said many times there is a great deal we do not know in the UK about our indigenous species from an angling point of view..and a lot to learn. From what I know I understand that those across the pond and the Europeans are far more knowledgeable about their own caddis
