two or three times a day to feed. Therefore we should be care- 

 ful to see that they are all at home before the nests are re- 

 moved. Spraying with Paris green will help to destroy all leaf- 

 eating caterpillars. 



THE CODLING MOTH. Codling is an old word for a cook- 

 ing apple. We know what a moth is (see pages 77 and 78). 

 We have seen an apple with a dark worm hole in it, and we 

 have cut the apple open and have found the little white worm 

 inside. Now for its history. In our illustration, fig. 59, g is 

 the moth about half an 

 inch across the wings. 

 The fore wings are grey, 

 the hind wings light 

 browji. As moths fly at 

 night we are, perhaps, 

 not so well acquainted 

 with it as with the white 

 larva. The female moth 

 lays her eggs upon the 

 little apple as it stands 

 up-right. The larvae 

 that hatch, usually enter 

 at the blossom end, 

 and bore to the core 

 and feed upon it. Since 

 the core is a continua- 

 tion of the stem, the latter weakens and the wormy apples 

 are the first to fall. After a while the larva eats its way out 

 and falls to the ground. Generally it crawls to the trunk 

 of the tree and after a little spins a cocoon from which in 

 about two weeks the moth appears and begins the laying of 

 eggs. Many of the larvae of this second brood are taken to 

 the cellar in the apples. To destroy them is important. All 

 wormy windfalls should be gathered up at once and fed to the
