Excerpt from Report of the Entomologist and Botanist, 1894
Western Ontario there are two broods. Prof. Saunders tells me that about London, Ont., during his long experience there as a fruit-grower, the second brood was invariably the more destructive. In California there are known to be at least three broods. It is claimed that so far there is no authentic record of this insect having been found breeding in British Columbia. Should it get introduced, it is probable that there would be two or three broods. The British Columbian Government have wisely adopted stringent measures to prevent the introduction of such a serious pest.
