APPLE PEST'S DOT 
Natural Enemies 
The minute black ladybird beetles 
(Stethorus vagans and Stethorus picipes) 
and the larvae of the syrphid flies prey 
upon this mite.

Coptodisca splendoriferella 
This leaf miner attacks apples, quince, 
and native hawthorns. When the larva 
is ready to change to a pupa, it cuts out 
the part of the leaf it has mined and 
drags it away to the twigs, where it is 
secured as a small cocoon about one-eighth 
inch in length, and remains with the en- 
closed pupa until the following spring. 
The larva is legless, flattish, the head 
dark brown, the body lighter brown with 
a darker shade along the middle above 
and beneath. 
The adult is a beautiful little moth, the 
head and outer half of the front wings 
golden, the bases gray. A silvery streak 
extends inward from both anterior and 
posterior margins of the front wing to- 
ward the tip, but they do not meet. 
The insect is not very common and 
those I have secured have been badly. in- 
fested with a small yellow and black 
Hymenopterous parasite.

Saddle-Back Caterpillar 
Sibine stimulea 
A slug-like caterpillar with four con- 
Spicuous horn-like spiny processes, one 
at each side near the front end of the 
body and the other pair near the hind 
‘end. There are other smaller processes 
at each end. Body purple in front and 
behind, between, pea-green, with an oval, 
Saddle-like area in the middle of the back, 
the green surrounding it having some ap- 
pearance of a saddle blanket. Length 
about one inch. 
The pupa is found in a brown papery 
cocoon, formed against branches or other 
objects. 
The adult moth expands about 1.44 
inch. The fore wings are of a deep red- 
dish brown color; hind wings, much paler. 
The insect is never common enough to 
be the occasion of any anxiety. Besides 
apple, it feeds upon oak, cherry, corn, 
and other plants. 
The San Jose Scale 
Aspidiotus pernicious, Comm. 
By H. F. Wi1ison 
Nature and Extent of Injury 
One can hardly fail to locate this insect 
where it is present in unchecked num- 
bers, for the appearance of its host will 
be such that one who is familiar with the 
resulting injury can readily distinguish 
the more or less circular ash-gray, shield- 
like scales on bark, leaves or fruit. Owing 
to the fact that the scales closely resemble 
the bark of most of our fruit trees, they 
may be working on a tree for some time 
before their presence is discovered. 
When they are abundant, the fruit will 
usually be infested with few to many 
scales; this is the first indication that 
the average orchardist will notice. When 
allowed to develop unchecked, they soon 
cover branches and limbs, which, as a re- 
sult of the injury, die in one or more 
seasons; following this, entire trees die 
from lack of nourishment. 
It has been said that the San Jose seale 
is the only scale which causes the redden- 
ing of the bark, but this is not true as 
the same effect is caused by other scale 
insects. This is quite characteristic of
