14 THE FLORIDA ENTOMOLOGIST 
notonously green landscape. But there was one exception. The 
sycamores planted along our streets and lawns were brown, sear 
and half bare. Why should they alone of all the trees on well- 
drained land be dropping their leaves? Let us examine the 
withered foliage. On the under side we find numerous reddish 
brown stains—so characteristic of tingids. A closer scrutiny and 
we see, in the middle of some of the fresher stained areas, the 
bugs themselves. Under the lens the entire body is seen to be 
covered with the most delicate net of thickened veins and ridges 
which gives these insects their name of lace bugs. And they or 
their stains were on every leaf. What a fearful epidemic is this! 
The worst human epidemic of which we have any record, the 
plague or black death of medieval Europe, is said to have taken 
over half of the population. But here is an epidemic which has 
taken nearly 100%. And it is a yearly event. Luckily for the 
trees it occurs late in the season, after much of the work of the 
leaves is done. Still it must be a handicap to the sycamore tree 
and one wonders if this may not be one of the reasons why 
the sycamore does not grow wild in our hammocks. 
DUSTING costs less than 
liquid spraying. 
Dusting materials cost more 
than materials for liquid spray- 
ing, but this is more than coun- 
terbalanced by the big saving 
in time and labor, less cost of 
the duster, and much smaller 
depreciation, repairs, and oper- 
ating cost. 
Dusting differs from spraying 
chiefly in that Insecticides and 
Fungicides are applied in a 
powdered form; dry instead of 
wet. Water merely carries the 
active ingredients to the plant, 
where it evaporates and leaves 
a dry powder. Spraying requires 
50 lbs. of water to carry 1 lb. of
