Added: 22nd February 2013 Description:
Confidence: It might be this. Notes: All 4 British/Irish Rhyacophila sp. are described as having mottled grey and yellow forewings while alive(2 of the 4 havent been recorded in Ireland yet, R. dorsalis has been). Barnard and Ross 2012 states- "Living specimens show a distinct dark diamond shape where the wings meet over the body at rest." I believe this feature is present here though I should have got a birds eye view picture and hopefully will do this summer. Apologies for the lack of measurements. Found in heather close to an outflow stream on a moorland lake. Other images of the adult insect are available here: http://www.euroflyangler.com/html/insects/species_taxa.php?id=9&ph=Arthropoda&sph=Hexapoda&cl=Insecta&or=Trichoptera&fa=Rhyacophilidae&ge=Rhyacophila&sp=dorsalis
No interactions present.
