TABLE 11. 

 Food of Etheostoma flabellare from streams. 



Summary of Food Habits in Etheostoma flabellare. 



1. The food in the younger stages of the fish consists of may- 

 fly larvae and midge larvas, the food animals being quite large 

 and proportionate to the size of the fish. 2. The larger spec- 

 imens continue to eat may fly larvae, the larvae of midges, the 

 larvas of other large insects and the adults of amphipods. 

 3. Amphipods do not appear in the food of the stream inhab- 

 iting fish. 



G. Etheostoma coeruleum Storer 



The rainbow darter occurs in swift streams often in com- 

 pany with Etheostoma flabellare. The food resembles that of 

 E. flabellare in that may fly larvae and midge larvae are eaten 

 at all stages after the fish becomes active. Entomostraca are 

 taken in fairly large numbers in the younger specimens but 

 they decline in importance as the fish increases in size. Snails, 

 larger insect larvae, a few small crayfish, midge larvae and may 

 fly larvce make up the diet of the larger specimens.
