Diptera and Perlidce. 



In imitations of Diptera and Perlidse the 

 body and hackle are put on in the same 

 way, except that the hackle should be 

 allowed to project sideways as well as 

 downwards ; for as the wings are hori- 

 zontal in these flies, the fibres which pro- 

 ject sideways will not interfere with the 

 position of the wings, as they would do 

 in the Alder and Caddis flies. The body 

 and hackle, when put on, should therefore 

 appear as shown in Fig. 14. 



The wings of these flies are perhaps the 

 most difficult of any to put on. To put 

 on wings which diverge from each other 

 as in the Blue-bottle,

 quill feathers from op- 

 posite sides, prepared 

 as described for the 

 Alder and Caddis flies, 

 should be laid upon FIQ lg 



each other, as shown 

 in Fig. 16. The hook should then be taken

 between the first and second fingers, with
