The precautions of thefe aquatic larvae, in fecuring 
themfelves in thefe retreats, are alfo neceflary to prote£t 
them from fifties, who are very greedy of them. Some 
of the phrygane® of ftagnated water, fuch as lakes and 
ponds, cat the Water lentil in regular fquares, from 
which they conftruft their edifices. The common trout 
is one of their greater! enemies; and many other fifties 
covet them l'o eagerly, that, when ftripped of their cruft, 
they make excellent bait. 
The phrvganea bicauda of Linn-etis frequents equally 
the banks of rivers and of {landing pools ; the wings are 
a third longer than the body, narrow at the top, and 
broad below, and reticulated with brown veins ; the co- 
lour of this infeft is a dark brown, with a fingle longi- 
tudinal ftreak palling acrofs the head and thorax ; the an- 
tennse are long, filiform, and of the fame colour with the 
legs and body * ; the appendices of the tail are of equal 
length with the antennae. 
The phryganea faltatria is one of the fmallefl fpecies of 
this genus ; the wings are decorated each with a green 
and white fpotf ; the antennae are longer than the body ; 
and when examined with a microfcope, appear velveted ; 
the wings are of a bright colour ; the lmall veins by 
which they are reticulated being white at the bale, and 
blackening towards their extremity J.
