106 ON CREEPERS. 
fly appearing through their thin creeper skins; they are 
much quicker in the water than the flies are upon land, up 
to the last moment before hatching. Some species may fix 
themselves to something, but it is certain that the greater 
part, if not the whole class, hatch themselves on the top of 
the water, and spring on the wing from the empty creeper 
case as it floats on the current. 
4TH.—GREEN DRAKE CREEPER.—Length, about three- 
quarters ; two short feelers, two or three whisks, which, 
with the legs, sides, etc., are fringed with hair. Ground 
color a lightish green, shewing, in the dim transparency, 
the dark marks of the fly within. Shape similar to the 
body and parts of the fly, but bulkier. A fine small line 
is visible betwixt the shoulders, where the creeper skin 
splits open at hatching; the same may be seen on the 
shoulders of the protective skin of the fly. They are gene- 
rally in deeper water, and hatch on the surface. 
5TH.—Brown DRAKE CrEEPER.—-Length, half an inch ; 
legs, whisks, feelers, and sides, fringed with fine hair, which 
flows and moves in the water. Isa broad and thick creeper, 
with largish head, altogether of a light ambry brown ground, 
touched and marked on the upper parts with darker. The 
checkwing creeper is nearly similar. Both shew the slant- 
ing dark lines on the sides, and hatch on the top of the 
water. 
6TH.—CORAL-EYED DRAKE CREEPER.—Length, about 
three-eighths ; whisks a quarter ; legs, whisks, feelers, and 
body, fringed with fine hair, and of a dull dim amber trans- 
parency ; eyes a ceep red brown ; wings shew through their 
thin creeper skins like an oblong black mark on each side 
of the shoulders. Hatch on the top of the water. Like 
the browns, the creepers of this class are readily taken by 
the fish, but preserve themselves in the same way.
