The white pine weevil, P. strobi (Peck), is able to feed and breed in a large 
number of spruce and pine species, both native and exotic. As a consequence, its 
range extends from coast to coast (//20). In eastern North America, eastern white 
pine is the most common host, but Norway spruce, wherever it has been planted, is 
attacked with almost equal severity. 
The adult (fig. 151A) is a small brown weevil 4 to 6 mm long. The elytra and 
body are covered with irregularly shaped patches of brown and white scales. Near 
the apex of each elytron there is a large white patch and a brown patch. In P. strobi 
these two patches are close together, and brown and white scales are often found 
intermixed.
