4 Practical Zoology. 



Fold the paper diagonally, with about an inch of each end 

 projecting ; drop the butterfly in, and fold the edges over to keep 

 it from slipping out. This may safely be carried in a box, a 

 pocketbook, notebook, or inside the sweat band of the hat. If 

 one catches an insect, with no other way of carrying it, it may be 

 pinned into the crown of the hat on the inside ; here is room for 

 it, and no one will be likely to notice the projecting tip of the pin. 

 An umbrella may be very useful in collecting. Hold the umbrella 

 spread and inverted under the branches of shrubs and trees, and 

 beat the branches with a stick, or jerk them with the handle, if it 

 has a hook. 



Collecting by Artificial Light. A lamp at a window, as when 

 studying, often brings valuable specimens. Electric lights along 

 the streets draw swarms of insects. It will pay the collector 

 to visit a number of lamps during the evening. Early in the 

 morning one may find some specimens, though many will have 

 flown or crawled away, and some may have been ruined by being 

 trampled upon. 



Sugaring. Many moths fly only at night. A favorite method 

 of capturing these is to make a thick sirup of brown sugar ; daub 

 this on the bark of trees, then visit these places to catch the 

 moths feeding on the sweet bait. The collector sets a series of 

 these baits, as a trapper sets a " line " of traps, and visits them in 

 series. A lantern should be carried ; the ordinary lantern serves 

 about as well as a dark lantern. Sometimes the bottle can be put 

 over the moth before it attempts to escape. In this way some 

 of the finest night moths are taken, and of kinds that are rarely 

 seen in the daytime. 



Breeding Cages. All the foregoing modes of capture are 

 likely to injure the specimens. The surest way to get perfect speci- 

 mens is to rear them. For this one may gather the cocoons and 

 keep them till the insects emerge. Better still, get the larvae, 

 keep them and supply them with food till they spin their cocoons, 

 or go into the pupa stage ; then one can be sure he knows the
