Yponomeuta malinellus (Zellar) - Apple Ermine Moth

Apple ermine moth is a defoliator of apple trees throughout Europe and Asia, as far east as Japan. It was introduced into New York State in 1909, into New Brunswick in 1917 and into Ontario in 1957, but was eradicated in all cases.

In 1989-1990 the apple ermine moth for the first time was found at many locations in the interior of B.C. For regulatory purposes the whole province is now regarded as infested.
