The Caterpillars of this Moth feed on the White and Black Thorn, 
together with feveral herbaceous plants ; it has been obferved to thrive 
_ better in the breeding cage when repularly fupplied with frefh gras, 
to keep the former in a proper ftate of moiiture. 
The Female depofits her eggs in June or July, the Caterpillars are 
hatched in Autumn, and remain in that ftate during the Winter; 
about the middle of May it {pins a large brown cafe, within which it 
pafles to the Pupa ftate; the Moths appear in June. 
In the Caterpillar ftate it is fcarcely poffible to diftinguifh the Male 
from the Female, except that the former is fmaller than the latter; but 
in the laft ftate their colours are entirely different, the Female being 
of a pale yellowifh teint, inclining to fox colour, the Male is of a 
rich brown. 
The Eggs are very curious, they refemble in fhape thofe of a Hen, 
but are neatly mottled with dark brown. 
The Caterpillars caft their fkins feveral times, and always thereby 
aflume a new appearance, though the general colours and character of 
the fpecies may be traced through every ftage. Our figure is copied 
from a very large and fine coloured fpecimen of the Female, that 
was met with at Darent-Wood, Dartford.
