For an entomologist, who wishes to study the owlet-moths 
of any region in a short time. there is no better method than 
to ‘‘sugar” for them. This is the technical name for applying 
a bait composed of the cheaper grades of molasses, sugar and 
vinegar. This mixture, if kept warm, will soon start a vinous 
fermentation. which seems to have a wonderful attraction for 
all owlet-moths that take food in that stage. For a number of 
years sugaring was carried on by myself at the Agricultural 
School, and immense numbers of moths were captured. The 
above mixture, which is of a treacle-like consistency, was 
brushed against the trees, and proved such an attraction that 
on certain evenings moths came in such numbers as to appear 
like swarming bees. The following list has been prepared to 
show the species of owlet-moths captured. and also to show 
the time at which they fly about to reproduce another genera- 
tion. The list contains the names of all noxious cut-worms, 
and may on that account be considered of practical importance. 
Strange insects are sometimes caught at such baited trees, 
insects that have never been found breeding in the north. For 
instance it is a common occurence to see large numbers of the 
cotton-moth fluttering around such baited trees. They are 
found only very late in the autumn, and always appear as if 
freshly issued from the pupa. This is very remarkable indeed, 
when we consider that such insects must have flown over that 
tremendous territory separating the wheat-belts of the north 
from the cotton-belts of the south. 
The most destructivespecies are marked with a star.
