The oystershell scale is one of the most common armored scale insects that cause injury to shade trees and shrubs. When this scale insect was first described in Europe in 1758, it was referred to as the mussel scale. See the link below to the Entomology Department, Penn State University factsheet on oystershell scale.

What is the origin of the shoe size scale?
Moederkoek
What is change of origin and change of scale?
Translation and dilation.
What is the effect of change of origin and scale on arithmetic mean?
The mean and scale will change by the factor of change for the sample data.
What is a numbering scale for a vertical axis?
It is zero at the origin, positive above and negative below. Otherwise it can be numbered to any scale.
What divides earth history's into units from its origin to the present?
Geologic Time Scale
How origin and scale effect arithmetic mean?
Suppose a set of observations for a variable X has a mean mx.If a scale factor of a is applied to the observations, and the origin is shifted to the left by a distance b, then the new mean will be (m/a)*x + b.
How change of origin or scale effect value of co-efficient of co-relation?
The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.
What feeds upon box elder trees?
Aphids, box elder bugs, cankerworms, cottony maple scale, maple bladder gall mites, maple leaf stem borers, oystershell scale, terrapin scale, white-marked tussock moths, and woolly maple leaf scale number among the predators that feed upon box elder trees. The woody plant in question, Acer negundo, tend to heave their ubiquitous roots and to showcase lush foliage and plenteous seeds. The result will be a food source which attracts invertebrates and vertebrates, of which the most famous is the box elder bug (Boisea trivittata).

Is Coefficient of correlation is independent of change of origin and scale?
The Coeffecient of corelation is definitely independent of origina and scale. If r(x,y)= cof or cor b/w X and Y let W=aX+b and Z=cY+d then r(x,y)=r( W,Z) Note that adding or subtracting a constant in all values of a random variable changes its scale. While multiplication or division change scale. The Form W=aX+b, caters the change both in origin and scale.
