 ments of close observation proved my suspicion, that the flying insects 

 were Gyrinus, to be correct, and I was able by careful watching for a 

 little while to observe the process entire. The insects after swimming 

 about on the surface for a time, or sometimes almost immediately after 

 coming to surface, would proceed to crawl up on the stones at the bank
