Imitations of Many Species 



resting place, its pellicle splits down 

 the back, and there conies forth the 

 perfect insect, differing much from its 

 previous form in color and in markings, 

 while its shape is entirely different from 

 that of its aquatic state. Its wings, of 

 which it has two pairs — ^the anterior 

 pair large, the posterior pair much 

 smaller — stand erect upon the body. 



To one who has made a study of an- 

 gling books and of Enghsh angling 

 catalogues it would appear that nearly 

 all the described species of duns must 

 have at some time been imitated in 

 trout flies. In 1886, Mr. Halford, in 

 "Floating Fhes and How to Dress 

 Them," gave a hst of ninety patterns 

 of dry-flies, most of which, though not 

 all, belonged to the ephemeridse family, 

 and in his "Dry -Fly Entomology" 

 (1897) he named one hundred patterns. 

 The study of English flies is a necessity
