This fly was hatched in a water-pot, on the 26th instant, 

 from a cod-bait creeper, which was put in the pot in May ; 

 water six or seven inches deep. It soon fixed itself to the 

 side of the pot, near the bottom. Fresh water was put in 

 night and morning, or rather oftener at first, and a gauze 

 cover over the pot. When hatched, was found on the under 

 side of the gauze cover, alive and perfect the creeper skin 

 on the surface of the water, and the empty artificial case 

 attached to the pot where it first fixed. 



Red dun. Hatching, and out in the evenings and after 

 dark. Full length an inch ; wings seven-eighths. 



Gravel spinner. Found several flies on the under-sides of 

 stones, by the water's edge, resembling this fly ; round 

 shoulders, striped light and dark brown, and about the same 

 size and colors.
