FLIES FOR APRIL. 65 



No. 12. STONE FLY. 



This fly comes from a water larva. It is heavy 

 in its flight, but uses its legs with extreme activity, 

 and is generally found amongst the stones, or close 

 to the sides of the water. I have kept an indivi- 

 dual alive for three weeks, during which time it 

 drank much water. It is in season from the 

 beginning of April until the end of May, and 

 should be used in the rapid parts of streams, and 

 on windy days where the water is rough.

 worsted or camlet, ribbed over with

 feather.

LEGS. A hackle stained greenish -brown.
