WORK AT HOME AND IN THE FIELD 



The wonderful acuteness of the sense by which the males of 

 certain species are enabled to seek out the females has already been 

 alluded to, and the possession of a suitable decoy will often bring 

 you a number of beautiful admirers without the least trouble, except 

 that taken in securing the decoy and preparing her temporary abode. 

 It is absolutely necessary that the female moth be one that has

 Here the gauze is attached to two wire rings, only a few inches in 

 diameter, and suspended by a string. Such a cage answers every

The sugar trap may be of much the same pattern as that in 

 which a light is used, but if intended for field work it should be of a 

 convenient size for portability. A lighter and far more convenient 

 form may be constructed as follows : 



Procure a large cylindrical tin box, and cut a circular piece of 

 perforated zinc just small enough to drop into it. Then make two 

 wire rings, one a little larger than the top of the tin, and the other 

 only about an inch in diameter. Next make a conical net of leno, 

 open at both ends, and of such a size that the two rings may form 

 the frames of its two extremities. "When the trap is required for
