INTRODUCTION. 



This list gives eight orders of interest to anglers, viz. :- 

 Order. 



4. Plecoptera 



6. Ephemeroptcra 



9. Hemiptera. 



11. Neuroptera 



12. Coleoptera 

 14. Trichoptera 

 16. Dipt era 



18. Hymenoptera 



Stone Flies. 



Mayflies. 



Bugs, Boatmen, etc. 



Nerve-winged flies. 



Beetles. 



Caddis Flies. 



Two-winged flies. 



Ants, Bees, and Wasps. 



in place of the five previously cited, solely due to the fact that 

 the Stone Flies, Mayflies, and Caddis Flies are placed in separate 

 orders instead of being grouped as " Neuroptera " — owing to the 

 different characteristics shown during their larval and pupal stages. 

 The specific names remain unaltered, as this book is intended for 

 the use of anglers rather than entomologists, we propose to follow 

 the time-honoured nomenclature of Linnceus. Stone Flies are thus 

 Pcrlidce as of yore, not Plecoptera, and Mayflies are Ephemeridce 

 and not Ephemeroptera. Let the Systematists grumble as much 

 as they like — the fish won't mind ! And for a long while to come 

 the old names will be the ones favoured of anglers. 



I. The Neuroptera, or nerve-winged flies, have two pairs of 

 wings, both pairs membraneous with extensive neuration ; certain 

 Ephemeridce, which have only one pair, make an exception to this 

 rule ; the imago has a biting mouth. 



By neuration is meant the system of nerves which constitute 

 the framework that supports the membrane of the wings. 



Selecting again only those families of the Neuroptera of interest 

 to anglers, we have the following : — 



Ephemeridce Mayflies, Duns, etc. 



Perlidce Stone Flies or Needle Flies. 



Trichoptera or Phryganidce Caddis Flies. 



Chrysopidce Lacewings. 



Sialidce Alder Flies.
