LARGE ELEPHANT MOTH. 
Ing to Moses Harris, changes into a brown 
Chrysalis on the second of August, or there- 
abouts; appears in it's winged state, on the 
twenty-third of May ; and may then usually 
be found in the marshes near Rotherhithe, 
which it much frequents. 
As the Caterpillar of this Moth feeds in 
marshy grounds, it is. observable that Nature* 
ever providently guarding each species from 
annihilation, has furnished the animal with a 
wonderful preservative from drowning, which 
is thus described by Moses Harris,-™ 
" Three joints of this Caterpillar,'* says 
he, " beginning at the second joint from the 
Tiead, are hollow; which the animal can fill 
with wind, or air, if by accident it falls into 
the water. These parts being filled with air, 
support the animal perpendicularly in the wa- 
ter, in exactly the same position as the float of 
a fishing-line, till it is wafted near any plant or 
blade of grass, by which it can disengage itself 
from that element, which in a short time would 
prove it's destruction.'*
