I. FIELD STUDIES 



Materials. 



I. Boxes for carrying insects. 2, A net. This may be 

 homemade, using mosquito netting or fish net and a stout 

 wire. If it is to be used for a dragnet for water insects, 

 the wire must be stout and the netting strong. Make the 

 net twice as long as wide. 3. A cyanide jar for killing in- 

 sects. 4. A few paper triangles for carrying butterflies. 

 5. A notebook. 



Note. — Your instructor will give directions for obtaining the material 

 called for in 3, 4, and 5. 



Directions. 



Look carefully and quietly in the various situations noted 

 below. Do not be in a hurry. Weedy meadows or vacant 

 lots and neglected roadsides are good places for your first 

 trips. Note concerning each insect found : (a) its name or 

 something by which to identify it, (3) where you found it, 

 {c) what it was doing, (^) its probable food. Record these 

 observations in your notebook. Make a special study of 

 such insects as your instructor may designate.
