Posts: 2737		The dark abdomen on this one is pretty striking. Does anyone know what species this is?

Posts: 1681		I probably shouldn't say anything after blowing that Paragnetina/Acroneuria ID, but I seem to recall that those black bands on the underside of the thorax are indicative of Agnetina.

Posts: 1681		Nice catch, Luke. Thanks for correcting the identity of this "cool perlodid." I wasn't very familiar with the Perlodini "springflies" when I made the earlier comment. While we're on the subject, do you recognize this one? http://www.troutnut.com/specimen/488
(Hint for those playing along: it's not Cultus or Arcynopteryx.)
