132 PISCATORIAL ENTOMOLOGY. 



frequents the surface of the water under shelving 

 banks and sheltered places, and is then styled the 

 bank fly. In common with the Spring Browns it is 

 considerably smaller in size during the hot months ; 

 but is more numerous on cold days. 



The Green-tail, or Grannum, completes this order of 

 flies. It appears at first sight like a freckled sand fly, 

 but upon a more minute inspection, is found to differ 

 considerably in several points. The body has a 

 strange appendage of a conspicuous green colour at 

 its extremity. This is its egg-pouch, and it is 

 observed to drop its egg, like the spinners of the 

 ephemeral order, as it rises and falls upon the top of 

 the water. 



The Perlidcs order ranks next to the above. The 

 most useful we have given as being the stone, 

 willow, and needle flies, also the yellow Sally. The 

 first-named is a very large fly, and in some localities 

 is termed the May fly, as it annually makes its first 

 appearance in that month. There is, however, the 

 same distinctive difference between this and the May- 

 fly, or Green Drake, that we have already described in 

 the February Red and the March Brown, with this 

 exception, that the wings of the Stone fly are double 

 the length of those of the Red fly, and lie still more 

 horizontally, being almost flat upon the back of the 

 insect. Except upon blustering windy days, these 

 flies are seldom " on " in sufficient quantities to excite 

 the attention of the fish ; though as a luscious morsel^ 

 the large fish seldom ignore even the solitary 

 specimen when it essays a paddling excursion across
