Entomological Notes. 307 



to it. If the apple remains on the tree, the worm comes out of a. 

 hole in the side, and takes one of two courses: it either spins a 

 web down to the ground, which is not very common, but it can be 

 induced to do so by a shaking of the tree, either by the wind or 

 otherwise (any artificial disturbance will cause it to spin a web, and 

 it will let itself down to the ground); or, under other circum- 

 stances, it crawls out of the apple down the limb of the tree, and 

 down the trunk, to where the bark is loose, and finds a place there 

 to spin its cocoon. It takes a very little space; a sixteenth of an 

 inch is an abundance for him, because he can gnaw as much as he 

 wants, to enlarge it. If he falls to the ground by means of his 

 web, he evidently has the faculty of seeing, because he heads di- 

 rectly toward the trunk, crawls up, and finds what the other has 

 found in coming down the tree, and spins his cocoon there. Then, 

 a third way is that the fruit, by means of his boring, has became 

 so far weakened, that it drops from the tree. In that case, the 

 worm goes on feeding until it comes to maturity on the ground, if 

 not already grown, and then comes out of the apple, and takes the 

 same course that the other one did that had spun down, crawls to- 

 ward the trunk of the tree, goes up, and finds a place in which to 

 spin his cocoon. 



Now the spot to trap him, apparently and really, is just at the 

 trunk of the tree. My practice has been this the past year, and I 

 have followed it faithfully, and can give you entire results: In the 

 first place, I scrape the trunk to make it smooth, so that he will not 

 have any chance to spin his cocoon outside of my arrangement; 

 then I have a piece of wrapping paper, which I fold up, and tie 

 around the tree. I want to make as many traps for him as I can, 

 and I fold the paper from two to three inches wide, fan fashion, 

 and then with a string it is tied about the tree, passing around the 

 middle of the paper. It is tied loosely, with a bow knot, so that 

 it is easily untied. The result is, that the worm will either craw! 

 in among the folds of the paper, or, as he seems to prefer, the space 

 between the inside of the paper and the bark of the tree. Here is 

 a paper that has been used the whole season. It is ordinary thiix 

 wrapping paper, and it would almost do for another year. I put 

 one of these papers around the trunk of each tree that had been 

 scraped smooth, as I said; and then I went around every Monday 

 morning, took off the papers, and counted the moths that were in.
