The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
Notonectdiae adults can leave the water and fly off whenever they wish. This specimen was caught when it landed on my car. These adults are one of the few aquatic insects that can protect itself with a strong beak.
This true bug was collected from the Touchet River in Washington on June 6th, 2011 and added to Troutnut.com by Bnewell on June 26th, 2011.
