40 Dr. Roxburgh's Account of 
as the purposes of nature are effected, and the females live only 
to produce the eggs on the branches of the trees, and then ex- 
pire. In regard to the Bughy species, they all take flight, females 
as well as males, and hence the natives firmly believe that they 
are all males, though I cannot see any physical reason for sup- 
posing them s%. I have frequently endeavoured to detain the 
males of the Jarroo species, and have kept them locked up in a 
box for that purpose ; but whether they did not like to make free 
with their female relations, or from what other cause I know not, 
but I could never obtain a breed in the domestic state, and the 
efforts of the male to escape were wonderful, and at last alwa} r s 
effectual. The accounts given by the natives of the distance to 
which the male insects fly are very astonishing. I have put, at 
different times and occasions, innumerable questions to them on 
this subject, and they assure me that it is no uncommon prac- 
tice amongst them to catch some of the male moths, and put a 
mark on their wings previous to letting them fly, the marks of 
different districts being known. I am told that it has been thus 
ascertained that male moths have come from a distance equal to 
a hundred miles and upwards ; I of course cannot vouch for the 
tjuth of this, but have no hesitation in declaring; that I believe 
it. The Jarroo worm is guarded on the trees in like manner as the 
Bughy ; this I have had opportunities of seeing on the hills west- 
ward of me : the cocoons are darker coloured than the Bughy 
species, and are wound off as described above. The accompa- 
nying skein I had reeled off at my elbow this morning; it consists 
of five Jarroo cocoons at first, of four when one cocoon was 
finished, and of three when two cocoons were ended : I then 
stopped the reel; the three that remained of course gave a fila- 
ment the entire length of the skein.
