are sometimes found in immense numbers on the flowers 
of the common white-weed, or ox-eye daisy, (Leucanthe- 
mum vulgare,) a worthless plant, which has come 
to us from Europe, and has been suffered to overrun our 
pastures, and encroach on our mowing lands. In certain 
cases it may become expedient rapidly to mow down the 
infested white-weed in dry pastures, and consume it, with 
the sluggish Rose-bugs, on the spot. 
“Our insect-eating birds undoubtedly devour many of 
these insects, and deserve to be cherished and protected 
for their services. Rose-bugs are also eaten greedily by 
domesticated fowls; and when they become exhausted 
and fall to the ground, or when they are about to lay 
their eggs, they are destroyed by moles, insects, and other 
animals, which lie in wait to seize them. Dr. Green in- 
forms us, that a species of dragon-fly, or devil’s needle, 
devours them. He also says that an insect, which he 
calls the enemy of the Cut-worm, probably the larva of a 
Carabus or predaceous Ground-beetle, preys on the grubs 
of the common Dorbug. In France, the Golden Ground 
Beetle (Carabus auratus) devours the female Dor, or 
Chafer, at the moment when she is about to deposit her 
eggs. I have taken one specimen of this fine Ground- 
Beetle in Massachusetts, and we have several other kinds, 
equally predaceous, which probably contribute to check 
the increase of our native Melolonthians.”
