HEMEROBIUS. 
The eggs of the hemerobius offer a curious fpeftacle 
to the obferver, and for a long time were deemed para- 
fttical plants. Each of them is fupported upon a long 
pedicle, refembling the (talk, of a plant, of which the egg 
appeared to be the flower. In this form they are feen 
in clufters upon leaves, where, as footi as they are 
hatched, thej find fubfiffence among the furrounding 
plant lice. 
In about fifteen days, the larva attains to its full growth, 
when it weaves to itfelf a fmall white filken cod of a 
clofe texture : there the hemerobius lodges about three 
weeks, till its metamorphofis into a winged animal is 
completed : If, however, the cod has not been fpun till 
Autumn, it remains in it till Spring, when it is tranf- 
formed. The flight of thefe infe&s is flow and heavy j 
fome of them have an excrementitious fmell. 
The hemerobius perla of Linnceus is one of the molt 
beautiful animals of this tribe : The eyes are golden, and 
the whole body of a yellowifh green * ; the wings are 
Very large, diaphanous, and of nearly the fame colour 
with the body ; it inhabits garden plants, and whea 
touched, has the fmell of ordure f ;
