FLIES FOE SEPTEMBER. 125 



No. 43. THE LITTLE PALE BLUE 

 DUN. 



This fly comes from a water nympha, lives two 

 or three days as shown, then changes to a more 

 delicate fly than that represented. It is upon 

 the water at the same time as the Whirling Blue 

 (No. 42), and lasts until the end of the fishing 

 season. It is very abundant, and taken equally 

 well by both Trout and Grayling. 



IMITATION. 



BODY. Very pale blue fur mixed with a very 

 little yellow mohair. 



WINGS. Feather from the sea swallow. 

 LEGS. The palest blue hackle to be had. 

 Hook No. 1, Grayling. 



To make it buzz, a sea swallow's feather only 

 may be wound upon the same body. 



The metamorphosis of this fly has very trans- 

 parent wings. It is too delicate to be imitated. 



REMARKS. This is called by some anglers the 

 " Willow Fly."
