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

Gravel spinner.—F ound several flies on the under-sides of

shoulders, striped light and dark brown, and about the same 
size and colors.
