AMERICAN TROUT-STREAM INSECTS 



each side of the body. When there is a dearth of 

 flies on the water, it is a good fly to use as a test in 

 getting trout to rise. 



No. 13. Orange stone. A smaller and more 

 brightly tinted stone-fly than No. 12, and with a 

 few different characteristics, though in the main it 

 is similar. I caught in May a great many speci- 

 mens of this family, and only place this particular 

 insect to show the more vivid color of the body. Its 

 size is just right for trout, and my imitation is very 

 successful. 



No. 14-. Horned spinner. (Slightly smaller 

 than the representation.) The horned spinner is 

 often seen among a cloud of brown drakes, where 

 they fly over the water, dipping and rising as the 

 two sexes meet. Sometimes the long horns, or feel- 

 ers, project forward, then again lie flat on the back. 

 In their wavy motions while flying they often touch 

 the water, and are sure to entice a rising trout. 

 When resting on a stone or leaf, their long legs fit 

 quite close to the body and the horns lie backward. 



No. 15. Crane spinner. This insect moves 

 about, sometimes resting on large stones that rise 

 above the water's surface, then alighting on smooth 

 shallow water, where it is taken greedily by the big 

 chub. Crane spinners invariably move in pairs; 

 and, though not abundant, they may be seen at all 

 times of day as well as of evening. The body of 

 the insect makes a good-sized tempting meal for a
