8 FARMERS’ BULLETIN 723. 
The following records from literature and from the Bureau of 
Entomology will indicate the times of hatching of the eggs of this 
insect in the spring for several localities: 
Ontario: Eggs hatch about June 1 (Jarvis). 
Connecticut: Eggs hatch usually between May 20 and June 1 (Britton). 
New York: Eggs hatch at about same time as those of oyster-shell scale. 
Ohio: Eggs hatch, and young are crawling, during latter part of May or in early June 
(Houser). 
Illinois: Eggs hatch from June 5 to 12 (Walsh). 
Missouri; Eggs hatch soon after the formation of the young apples, the date depend- 
ing upon locality and upon forwardness of the spring (Taylor). 
District of Columbia: Eggs hatch from May 15 to June 1 (Howard). 
Delaware: Eggs hatch about same time as those of oyster-shell scale, which is usually 
early in May (Houghton). 
Tennessee: Eggs hatch in April, and there are two broods annually (Bentley). 
Georgia: In 1906 eggs hatched March 11 to 22. Eggs for second brood hatched 
beginning about June 2. 
In the more northern States there is but one brood each year, but 
in the South, as in Tennessee and in Georgia, there are evidently 
two full broods, and in the latter State there is a strong probability 
of a third. Thus, at Myrtle, Ga., in 1906, the eggs were hatching 
March 11, and hatching had probably ceased by March 22. Males 
of the new brood appeared May 15, and eggs had been deposited by 
the female May 28, the hatching beginning June 2.
