even after their transformation, preferve their carni¬ 
vorous inclination; not fatisfted with making war 
upon the plant-lice, they do not fpare each other. 
The eggs of this infeft: are borne upon fmall pedicles, 
which are nothing but a gum fpun out by the hemero- 
bius ; the egg remaining fattened to the upper part 
of the thread: thefe eggs are depofited upon leaves, 
and fet in the form of bunches ; they have been taken 
for parafitic plants. The larva when hatched, finds 
there its food, in the midft of plant-lice : in fifteen 
or fixteen days it has attained to its full growth. 
With its fpinning-wheel at its tail it makes itfelf ar 
fmall, round, white, filky cod, of a clofe texture. 
In fummer, at the end of three weeks, the hemerobius 
ittues forth with its wings ; but when the cod has not 
* , , 
been fpun till autumn, the chryfalis remains in it the 
whole winter; and does not undergo its final meta- 
morphofis till the enfuing fpring. 
The flight of this infeft is heavy: fome fpecies 
have an excrementitious fmell. 
One goes by the name of water-hemerobius, be- 
caufe it lives mottly at the water-fide. 
Thefe infe&s have been known to fpin their filky 
fubftance fo as to cover a large fhrub ; and the filk has 
been ftrong enough to bear winding upon a bottom 
of card.
