BAIT AND FLY FISHING. 81 



in the manner described above. I thought 

 the more tartan-like the better. 



No. 6. This fly is found on most of the 

 rivers in Scotland. I have described it 

 before, comparing it to the eel beetle, which 

 I put with it in my third class breeding on 

 land and afterwards going to the water. In 

 its habits of life, it is more peculiar than 

 any of the amphibious flies that have come 

 under my observation. It chooses a dry 

 sand-bank near the edge of a river, and 

 deposits its spawn among the sand where 

 the grass is thin. After passing through 

 the ova, grub, and chrysalis states, it comes 

 out in the following June in its original 

 form. It then pairs, spawns, and goes to 

 the water, between which and its native 

 sand-bank it is constantly traversing. It 

 seldom takes wing, but on very bright 

 sunny days may occasionally be seen flying 

 close over the surface. It stands and walks 

 on water the same as on land. This fly 

 may be imitated by a feather out of a land- 

 rail's wing, or a brown fieldfare's tail, for 

 wings; and dark wool or hair, or a dark 

 feather from a black cock, for body and legs.
