CREATURES THAT GAME-FISH EAT 25 



will not touch it. I have tried it in pools where 

 large brown trout abide near where bass lie, and 

 the bass have always responded to it. 



The hellgranimite is the aquatic larva of a fly, 

 the horned corydalus {Corydalus cornutus), some- 

 what resembHng and closely allied to the dragon- 

 fly. It is supposed to exist for several years in 

 the larval state under loose rocks on or just be- 

 low the water-line of rivers and other waters of 

 low temperature. Here its life is spent in devour- 

 ing other smaller insect larvae, and during this 

 period it is most suitable for baiting purposes. 

 But this repulsive-looking, yet harmless, creature 

 is used as bait in all three stages of its life. First 

 in its larval — creeper stage; then in the dormant 

 pupa stage, and last after the final change into 

 the adult flying insect. The corydalus is a large, 

 fierce-looking insect with four gauzy wings w^hich, 

 when at rest, lie flat over the body, which is a 

 cinnamon color on the belly, dark brown at the 

 sides, and dull black at the head and thorax. It 

 begins its flight after dusk and, like the creeper, 

 is entirely nocturnal in its habits. I have never 

 seen it in flight during the daytime in New York 

 . regions. This fine, large insect is very abundant 

 on Montana streams, where it is used extensively
