Found on a small round fence post in a field next to the beach. Was VERY camera shy...which meant I was climbing and re-climbing fence and going round in circles to try and photograph them...one of my neighbours thought I was doing some kind of dance / gone mad  .So hopefully I'll get a reply to this post (unlike last 2 here )Regards Roger Sorry about poor quality of photo's...blame the insect....

I'd say stone flies, Plecoptera.

Thanks Paul these have not been recorded here since the 19th Century,King (1890). Doesn't mean they haven't been here since then though...not many people interested I guess . The ones recorded then were;Leuctra fusciventris and Chloroperla tripunctana. Regards Roger |

Leucetra is brown, Chloroperla is more yellowish. At least, in my insect guide. I just put my Dutch key in storage, so cannot check that one.

They look like Nemouridae to me - the wings on Leuctra are usually more rolled around the abdomen. John |

Regards Roger It's OK Roger - you've finally found my weak spot - the "Riverflies" (Ephemeroptera, Plecoptera and Trichoptera). I am human, not really a search engine with an avatar!

Hi Tony Sorry if that is the impression I was sending out, it certainly wasn't intended. I appreciate ALL the people who have given ID'S to the photo's I have sent to D.I. Without you folks my pics are just pics of insects, nothing more. To be able to show someone a pic of a fly/beetle or whatever and tell them what is called gives the subject a lot more meaning. I always say where I got the information...Knowledgeable people at Diptera.info. Regards Roger |

Leuctra fusciventris is an old name for Leuctra fusca. There was a species list, possibly unpublished, attached to the Nature Conservancy Council's copy of The Natural Environment of Shetland (ed. R. Goodier, 1974) that included the stoneflies Chloroperla torrentium and Leuctra inermis from Pobie Sukka, Many Crooks inflow and White Helliacks; and C. torrentium and Nemoura cinerea from Loch of Tingwall. The list was undated. It was attached to RH Britton's chapter The Freshwater Ecology of Shetland. The 3rd edition FBA key to stoneflies (Hynes 1977) includes vice-county distribution maps, and Shetland is blacked in for Brachyptera risi, N. cinerea and Leuctra inermis but not Leuctra fusca, Chloroperla torrentium or C. tripunctata. I've just read about your mishap. Glad you are on the mend. Best wishes John |

Thanks John...I was only going by the Checklist of Insects supplied by SEG on Nature in Shetland Website. I've changed the photo to another dire shot (Dorsal) so wings can be clearly seen....Hope this helps some. Regards Roger |

Definitely Nemouridae - two veins make a broad X halfway along near the front edge. To get to species requires genitalia examination. John |

Thanks John They seem to be enjoying putting their genitalia to the test in the photo's, so Nemouridae it will remain. Regards Roger |
