44 STONE FLIES— FERLW^. 



The Willow fly (fig. 55) comes on later in the 

 season. It is seen flying in the sunshine at times in

 abundance on most stony streams, and is the last type 

 we propose to show of this interesting and useful 

 family of flies.

 bers of the Ray, Linnean, and other societies, and it is 

 stated that there are about thirty varieties indigenous 

 to this country. As their name suggests, all frequent 

 stony rapid streams, and in consequence their imita-

 upper waters of our rivers.

 angling season closes. The sight of this plate recalls 

 many happy days of glorious success with baskets of 

 fine fish, taken with the large stone, fly when the 

 elements were capricious and anything but favourable, 

 also when the conditions were fine and bright, and the 

 fish were taken from amongst the stones, almost on the
