]24 flip:s for September. 



No. 42. THE WHIRLING BLUE 

 DUN. 



This fly comes from a water nympha, lives 

 about three days as shown, then turns to a 

 Light Bed Spinner. It is in season until the 

 middle of October, and on the water chiefly in 

 blustering cold weather. It has been supposed 

 to be a second edition of the Yellow Dun of 

 April. If compared with that it will be found 

 rather smaller and more of a crino-er colour.
