 Of late years the Hessian Fly has been detected in England. It is 

 apparently a common European species, and indigenous in our own. 

 country, as well as on the Continent ; but it is much less destructive 

 in Europe than in America. This is thought to be explained by the 

 theory that the insect was imported into America unaccompanied by 

 the numerous parasites which prey upon it, and materially reduce its 

 numbers in Europe.
