AMERICAN TROUT-STREAM INSECTS 



Nos. 9 and 10. These are, I fancy, male and 

 female. They are quite common day flies in the 

 latter part of the month, flitting about near the 

 bushes, but always over the water. No. 9 is mot- 

 tled in varicolored browns; the horns, divided into 

 eight sections, and the very long hind legs, are all 

 bright brown in color. They are swift in flight, 

 which makes a kind of buzz, like a bluebottle. No. 

 10 is exactly like No. 9 in shape, but it is a little 

 smaller and the color is varicolored greens and 

 grays. 



They are four-wing flies and are quite plentiful 

 enough to warrant an imitation being made and 

 tried. 



No. 11. A deep black, shiny insect, covered with 

 hairs. It seems to be of the spinner family. It 

 has two wings of a dull gray; the ends of its legs 

 are black, the inner sections a bright brown. It 

 stays over the water and is very rapid in flight. 



No. 12. A small, deep black gnat, very plenti- 

 ful both day and evening. This is one of the rare 

 insects to be out on hot days. I find at this late 

 season when trout will not be persuaded to come up 

 after large flies, these little gnats often succeed in 

 enticing them to rise. There is another gnat of a 

 similar shape, but brown in general tone. It is a 

 pretty fly, likely to be successful, as it stays over 

 the water and is very rapid in flight near the sur- 

 face.
