HABITS OF THE LARVA OF BELLURA MELANOPYGA. 113 



fatally effectual in attracting the attention of fish. A number of 

 instances were observed in which specimens thrown out were not 

 molested so long as they remained motionless but unfortunately 

 for them they remain quiet for only short intervals, often not 

 exceeding 60 seconds, and soon after swimming began were 

 snapped up. Fish of all sizes appeared to feed upon them. The 

 larger fish always secured the prey at the first dash but small fish 

 were observed to make three or four attempts before the full- 

 grown larva could be secured. 



The large water stricler (Gerris sp.), common in the Douglas 

 Lake region, was observed to attack the larvae when they 

 happened to be on the surface of the leaves. The ultimate 

 effects of such an attack were not observed since in every case 

 the larva attacked happened to be under observation for other 

 data and the striders were driven off.
