104 ON CREEPERS. 
the time when they produce their flies ; they then repair to 
the shallows and edges of the streams, to fix to some sub- 
stance preparatory to their hatching. Some leave the water 
and run up the stems of plants that grow by its side, and 
fix to the under-sides of leaves, but according to observation, 
by far the greatest number fasten themselves by the belly 
and under-parts with some sticky matter peculiar to them, 
to the under-sides of stones that lay just without the edges 
of the water, which enables the flies to split open their 
creeper skins at the shoulders, and unsheath their legs, 
whisks, and feelers. Numbers of the empty creeper skins 
may be seen on the under-sides of stones taken up by the 
hand, just without the edges of the water, and often the 
new-hatched flies beside them. 
1st.—StTone Fiy Crerper.—Length about seven-eighths, 
head, shoulders, bedy, legs, whisks, and feelers, resembling 
those of the flies, but more bulky, and the legs are fringed; 
ground color of the upper parts, brown, of lighter or darker 
shade, distinctly lined and marked with dark brown ; belly 
and under-parts shades of yellow. At the time of hatching 
they repair to the edges of the water and fasten themselves 
to the under-sides of stones, where they hatch their flies, 
and are found by the natural flyfisher ; but soon after they 
find other places of repose. They are the largest creepers, 
and produce the largest and master fly of the angler’s list. 
In April they are in perfection, and are found under loose 
stones that lie hollow in shallow streamy places, and near 
the edges of the water. Trout roam in search of them. 
2nD.—NEEDLE Brown CREEPER.—Shape and size nearly 
similar to those of the bodies, legs, etc., of the flies. Colors 
‘brown, of lighter or darker shade. Is the smallest creeper, 
and produces the smallest fly of the browns class. Numbers 
of them may be seen on the under sides of stones, taken up
