TREES AS GOOD CITIZENS 
becomes conspicuous on a twig by the 
appearance of white egg masses resemb¬ 
ling cotton. The eggs hatch from early 
summer to August, and soon after hatch¬ 
ing the young settle on twigs and the 
underside of leaves and begin to feed, 
causing the leaves to turn a sickly yellow. 
Sometimes the leaves become covered 
with honeydew. Badly infested branches 
are apt to die. In winter the parent scale, 
brown in color, oval shaped, and about 
T V inch long, is found on the under side of 
twigs and branches. 
ing with a stiff broom over the surface 
covered by the white egg-masses will 
probably destroy the eggs and thus prevent 
the production of a new brood. In some 
communities the eggs are destroyed by 
jets of water at high pressure, applied by 
a power sprayer. Cutting and burning 
twigs carrying the egg-masses is simple 
and useful. 
Gloomy Scale 
Habits Although it prefers the soft 
and or silver Maple, this scale is 
Damage, apt to damage all Maples. Its 
attacks are especially common 
in the South. In appearance the scale te 
yellow and shaped like a pouch. The 
immature scale spends the winter attached 
to the bark, and devotes the spring to 
feeding. Its eggs are laid and hatched in 
the early summer, and the young crawl 
about for a day or two before settling 
down to feed and build new scales. Sev¬ 
eral generations follow the first, during the 
summer. The presence of the scale is 
indicated by a roughening of the smooth 
bark and the appearance of dark gray, 
scurfy patches with grain-like surface. 
Wherever the scales may have peeled off, 
white rings are found. 
Remedy. Miscible oil solution is the 
most efficient means of con¬ 
trol. This solution should be applied by 
spraying during the winter. It will usu¬ 
ally be found to serve the purpose. 
Terrapin Scale 
Habits This scale takes its name 
and from resemblance to a mini- 
Damage. ature terrapin. It is a raised, 
reddish scale, to | inch in 
length and half as wide, with ridges along 
its edges. The scale encrusts twigs and 
drains their vitality by sap-sucking, caus¬ 
ing the foliage to wilt and die. The hatch¬ 
ing season extends from June through the 
greater part of the summer, and the young 
insects, of licelike appearance, infest green 
shoots and the large veins of the leaves. 
On the infested twigs, and beneath them, 
a sootlike growth and honeydew are to be 
seen. It also infests Oriental Plane. 
Remedies. Early spring spraying 
applied before the buds have 
opened, is an efficient method of control¬ 
ling this insect. For this purpose kerosene 
emulsion and miscible-oil solution are 
most satisfactory.
