Order EPHEMEEIDA 



Ephemeridae. The May Flies 



The proper way to collect this order is to wade up brooks 

 gently sweeping the vegetation on either side, just at dusk, 

 or to work around the edges of ponds at the same time. When- 

 ever there is a strong wind blowing across a pond and a hatch 

 is on, the flies will be carried to the leeward side and often 

 to a considerable distance, and sweeping and examining trunks 

 of trees along the edge of the pond will produce results. Dr. 

 H. T. Spieth tells me that the tendency of the flies when leav- 

 ing the brook is to go toward the dark, and that the males will 

 go up the side of clitTs to a considerable height.
