AMERICAN TROUT-STREAM INSECTS 



is left in the stomach of a trout. It is an excellent 

 floater on the surface, and with its wings erect and 

 close together it tempts a trout to feed as no other 

 insect can. Toward the end of the month the rise 

 gradually diminishes; but, as in April, so in part 

 of June, they still are seen, though only in scat-

 It is one of the few drakes with three stylets; the 

 majority have only two. The rise begins early in 

 the month, and later you see the yellow drake 

 everywhere, both day and evening.

 make it seem a much larger insect than it is. At
