WINTER NUMBER 41 
Empoasci mali—The “Green Fly.” This little jassid or leaf 
hopper, which is commonly called the ‘Green Fly,” made its ap- 
pearance very late in the spring, and caused injury only in small 
areas during the entire summer. This is quite an unusual oc- 
currence since snap beans maturing in March are often severely 
attacked, and cowpeas may be entirely destroyed during the 
average summer. The reasons for the scarcity of this jassid dur- 
ing the year are not known, tho many farmers attribute it to the 
cold in early February. No satisfactory control measures, are 
known, even on truck crops. The promising contraption for 
catching the leaf hoppers invented by Mr. Oller of Delray is not 
now in use, because, altho thousands of the insects were caught 
the numbers remaining in the fields were not perceptibly reduced. 
On account of its wide range of food plants swarms of this jassid 
may come in from adjoining lands. 
Laphygma frugiperda—The Fall Army Worm. The habits of 
this insect seem to be slightly different in South Florida than in 
other parts of the United States, in that altho they are extremely 
numerous during spring, summer and fall, particularly in corn 
fields, they rarely assume the “army” habit. There are few of 
our insects that do more damage than the Fall Army Worm, and 
the limited acreage of corn on the lower East Coast is not in- 
creased because this insect is present. Corn planted in February 
or early March can mature and escape with only slight injury, 
but later plantings of corn, other than the Nassau corn and its 
close relatives which have some immunity, are usually riddled 
and sometimes even its ensilage value destroyed. Altho some 
farmers have tried to control the pest with arsenate of lead, few 
of them have been persistent, and little good has resulted. This 
species is more often found in the ears and damages them more 
in South Florida than the common corn ear worm, Heliothis ob- 
soleta. 
Diabrotica vittata—The Cucumber Beetle. Just how long this 
species has been in South Florida is uncertain, estimates varying 
from two to five years, but certainly in that time it has come to 
be one of our most important insects. These beetles were in the 
fields in considerable numbers during the freeze in early Febru- 
ary, which apparently did not injure them. Altho their prin- 
cipal injury is to cucurbits, sunflowers and other plants are 
sometimes injured, and during the spring the writer saw them 
attack the tender foliage of citrus trees in a few localities. They 
occur on the cucurbits in such swarms that the usual poisons
