THE INSECT FOOD OF TROUT 



I AM indebted to an entomological authority, and 

 fishing friend, for the following notes on some of 

 the aquatic animal life he has found in the Eden 

 and its tributary streams. 



Small dragon-flies of the Agrion species. 



Duns of the Baetis species ; abundant beneath the 

 stones of streams. 



Several species of Caddis-fly larvae, which the 

 trout apparently take case and all. They are as 

 follows : 



Stenophylax, Micropterna, Halesus, Sericos- 

 toma and Plectronemia species. These all have 

 cases of small stones. Caddis-fly cases are 

 frequently found in fish that have just been caught. 



There are a number of beetle larvae, which fall 

 victims to the trout. Two or three species of 

 Agabus breed freely, many Hydropori, several 

 species of Haliplus, two species of Deronectus, and 



one of the very abundant but seldom seen species
