Cicada invasion in eastern Canada?

 The recent appearance of numerous cicadas has many Canadians in the maritimes concerned but according to David McCorquodale, Dean of Science and Technology, Cape Breton University there is nothing to be concerned about. “In Nova Scotia there are no reasonable ground to be concerned about a mass emergence of cicadas this summer.  The three species of cicadas in Nova Scotia all have an annual life cycle.  Numbers of adults that emerge each year are similar.  We will not be able to see any difference in populations of adults this year compared to other years.”
