The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
These tiny little aquatic mites show up in my samples from time to time. This fairly large one is only about 1mm long, so these aren't relevant to trout, but it's interesting to know that they're down there, anyway.
This arthropod was collected from Mystery Creek #62 in New York on April 1st, 2007 and added to Troutnut.com by Troutnut on April 2nd, 2007.
