HOW TO KNOW THE INSEQS 



course about dusk by daubing the bait here and there on tree 

 trunks at convenient heights. A paint brush serves vrell for this. 

 A circular course which can be traversed in tv/enty minutes or 

 half an hour is good. By the time the last tree is painted '.7ith 

 the bait, early arrivals may likely be found at the first trees 

 and the fun begins. Many of the moths will drop into an open 

 killing Jar held Just below them. Others will fly and may be 

 caught with the net. Sugaring offers the best way to catch the 

 beautiful big underwlng moths ( Catacola spp . ) . Beetles, ants, and 

 other Insects come to the bait. One may go around the course 

 several times in one night to advantage. The same course m:ay be 

 touched Up a bit with fresh bait and be even better the seconder 

 third night. A sultry evening v.lth a storm threatening, makes an 

 ideal time for sugaring.

Separators and Collectors 



i_j, 



A device for more easily picking up small 

 Insects (Fig. 10) may be m.ade from a wide 

 mouthed bottle or celluloid vial, some bits of 

 glass or metal tubing, and small rubber hose. A piece of fine 

 gauze should be tied or soldered over the tube at (e) to prevent 

 foreign matter entering the tube as the user draws air through 



Loose soil, moss, dead leaves, fungi, decaying v/ood, etc. 

 harbor many species of small Insects. Sifting such material 

 through a fine mesh sieve on white paper or cloth v/ill reveal 

 many specimens, A separator may be m.ade which will autom.atically 

 do the work more completely and much easier. Take a clean cloth
