Have fished this lake for 40 years and have never been aware of a beetle hatch. The odd beetle, bee, flying ant, etc. but never in the numbers that I witnessed this morning. The beetle had an iridescent green wing and a dark brownish/blacking underside. About one quarter of an inch in length hundreds of them on the surface. I did not see any fish on them because I believe the fish were preoccupied with the daily damsel factory. If the damsels would not have been there, it might have gotten interesting. Quesitons: 1. Do you suppose these beetles were aquatic and thus an actual hatch? 2. What might the underwater stage look like? 3. Has anyone encountered these critters in these hatch-like numbers? 4. Has anyone seen fish actively surfacing for these beetles? 5. Do you have an immature representation?
