Simon Lidster 0 Report post Posted February 21, 2012 Anyone identify this big green ugly bug? From a kick sample the other day on the river Derwent in Derbyshire, UK. Plenty of Baetis, stoneflies, Hydropsyche and Rhyacophilia plus Danica, but cant find out what the green bug is. Its about 2-3 cm long. Thanks, Simon Quote Share this post Link to post Share on other sites
rockworm 0 Report post Posted February 21, 2012 They look to me like the larvae of an aquatic fly. Predators which live in the muck. You would probably need to dissect one under a microscope to identify the species. Quote Share this post Link to post Share on other sites

JSzymczyk 0 Report post Posted February 23, 2012 a species of cranefly was my first impression too. It is without a doubt some sort of Diptera because of the lack of true legs(segmented, jointed legs) and the presence of pairs of fleshy prolegs on the abdominal segments.

If you make it I bet first cast you will get a strike with out a doubt! Quote Share this post Link to post Share on other sites
Simon Lidster 0 Report post Posted July 2, 2012 Ok, got the definitives on these two, the one on the left is a cranefly and the one on the right is a snipe fly. Massively outnumbered by Baetis, Caddis, Ephemera etc etc... Simon Quote Share this post Link to post Share on other sites
