the pupa of the Groat Moth and others of the Bomby- 

 cina, and serving for the same purpose. / 



This may be noticed in any garden in the case of the 

 Argyrotoza Bergmanniana, a pretty little Moth, the 

 larvae of which are exceedingly destructive to roses, 

 feeding sometimes in the flower-buds, and sometimes 

 uniting the young leaves at the extremity of a branch 

 so as to form a chamber, in the interior of which the 

 larvae feed and change to the pupa state. When the 

 perfect insect is ready to appear, the pupa works its 

 way out of its bed of leaves by the agency of these 

 abdominal spinules, until a considerable portion of it 

 is projected out of its dwelling, when the little Moth 

 is able to creep out without turning a feather of its 

 delicate wings; and the empty pupa- cases may often 

 be seen in July and August, the period when the 

 Moth flies, sticking out from amongst the joined 

 leaves of rose-bushes. 



Such habits as these, however, are by no means 

 universal in the tribe, and some of our fruit-trees will 

 furnish us with examples of a very different mode of 

 proceeding. In the month of May, a little Moth, 

 about three-quarters of an inch in expanse, and of a 

 greyish colour with a reddish-brown, gold-bordered 

 spot at the hinder angle of the anterior wings, 

 may be found flying about apple- and pear-trees in 

 the evening. This is the Codling Moth (Carpocapsa 

 Pomonella), and its object in frequenting our gardens 

 and orchards is, to lay its eggs upon the young fruit 

 of the above-mentioned trees, into the interior of 

 which the larva then bores, and feeds in security 

 upon their substance. It is remarkable, and says 

 much both for the sagacity and the maternal affection 

 of the Moth, that she always selects the best kinds of
