Abstract
One of the most interesting studies of teh scientific entomologist—more interesting because of its economic importance—relates to variation of habits of insects, consequent upon variation in their environment. The carpte beetle, Anthrenus scrphulariœ Linn, feeds on flowers in its native Europe. In the new atmosphere of America, it feeds and thrives upon carpets, shawls and other woollen goods. The apple maggot, Trypet pomonella, feeds upon our wild haw and other wild fruits. Civilization exterminates its old-time aliment; and it betakes itself to our apples, cherries and plums/ The curculio, apple-tree borers, bark lice, etc., are other illustrations of the same truth.
