 HABITAT OF AQUATIC INSECTS 



IT is in the shallow warmer water that much of the 

 insect food of fish must be looked for. Water that 

 has been said to be richer in living things than in 

 any other element of the earth's surface. In it 

 grows that plant life to which many of the aquatic 

 tribe cling, and hide from their enemies. 



But the different orders of aquatic animal life have 

 their own particular likes and dislikes in regard to 

 habitat. For example it is not in shallow fresh water 

 that you must expect to find the mutitudinous gnats, 

 but in the muddy, ditchy places where vegetable 

 life is rank, and the green top-growth covers up a 

 dense undergrowth of decay. 



For the Perla nymph it is necessary to wade into 

 the middle of stony, turbulent streams, and for the 

 stone-fly to search the often still more stony, dry, 

 gravel beds.
