10 INTRODUCTION. 



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

 Order. 



4. Plecoptera Stone Flies. 



6. Ephemeropiera Mayflies. 



9. Hemiptera. Bugs, Boatmen, etc. 



11. Neuroptera Nerve-winged flies. 



12. Coleoptera Beetles. 



14. Trichoptera Caddis Flies. 



16. Diptera Two-winged flies. 



18. Hymenoptera Ants, Bees, and Wasps, 

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

 the Stone FUes, 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 LinncBus. Stone Flies are thus 

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

 and not Ephemeropiera. 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 

 EphemeridcB, 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 : — 



EphemeridcB Mayflies, Duns, etc. 



PerlidcB Stone Flies or Needle Flies. 



Trichoptera or PhryganidcB Caddis Flies. 



Chrysopidee Lacewings. 



Sialidce Alder Flies.
