AMERICAN TROUT-STREAM INSECTS 



water on a bitter cold day when it was snowing. It 

 has unusually large shoulders and a very small, 

 black body, with wings that appear yellow while in 

 flight. The gray-yellow wings are mottled in 

 brown, and the black legs are quite hairy. This is 

 another insect of larger size in April. I am confi- 

 dent of its ability to lure trout better than any ex- 

 isting pattern for cold and stormy days. My imi- 

 tation has been tested and found good even during 

 ' cold days in May. 



This fly was absent the latter part of the month 

 when the temperature was much higher. It is of 

 less consequence what date these insects were cap- 

 tured; but it is very important to know what kind 

 of weather they are on the wing. A study of the 

 monthly chart will enable the angler to know what 

 artificial he should use in different weather condi- 

 tions. 



No. 4. Brown drake {March brown). This 

 has its greatest rise in May, but if the weather is 

 warm at the latter end of April it appears in flight 

 in fair numbers. The first specimen I saw was on 

 the 28th, in balmy springlike weather. I shall defer 

 a description of this insect till May ; but as it some- 

 times does happen that warm weather comes early, 

 it would be advisable to have a few brown drakes 

 in stock ready for use, because this fly is of the first 

 rank in getting a rise of trout.
