FLIES FOR SEPTEMBER. 



No. 43. LITTLE PALE BLUE DUN. 



This fly comes from a water nympha, lives two 

 or three days as shewn, 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. 



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

 may be wound upon the same body. 



The metamorphosis of this fly has very transpa- 

 rent wings. It is too delicate to be imitated.
