FLIES FOE APRIL. 85 



male has a brownish red crown or cap on his 

 head. The female is also crowned, but her cap 

 is too small to be easily seen. It is in season 

 from the latter end of April until the middle of 

 June, and is on the water chiefly on cold days ; 

 influenced by weather in a manner similar to the 

 Blue Dun. (See No. 2.) 



IMITATION. 



BODY. Blue fur from a mole. Reddish brown 

 floss silk may be tied on for the head. 



TAIL. A whisk or two out of a yellow dun 

 hackle. 



WINGS. From a feather of the under- side of 

 the cormorant's wing ; or, in default thereof, 

 a feather from the breast of the water hen, the 

 tip of which must be used. Or the upper end 

 of the wing feather of a tomtit when in full 

 plumage. 



LEGS. A very small yellow dun hackle 

 Hook, No. 0, short. 



It is difficult to find a hackle feather of the 

 tint proper to make this fly buzz. 



REMARKS. A feather from the Merlin hawk's 

 wing may be used, if procurable, to wing this 

 fly. (Arundo, p. 29.)
