REARING AND RECORD KEEPING 201 



Record Blanks 



Records of individual observations. — Rearing work yields 

 practical knowledge of insects. A good means of making it 

 specific and permanent is the making of records of observa- 

 tions on particular species. For this purpose two outlines 

 for the use of students are offered on the next two pages. 

 One of these calls for observations on the feeding, locomotion, 

 resting, shelter-making, defensive and other activities of the 

 insect selected for study. The task is one of quietly watching 

 the insect and of recording what is seen. 



The second outline is for the use of any one who may 

 have the industry and "stickability" to rear some insects 

 through their entire life cycle from the egg to the adult. 

 If such be selected as are easily supplied with common food 

 and have a brief life period, this is not a difficult task. 

 Certain common garden insects, like the cabbage butterfly, 

 or noxious household insects, like the mosquito, are most 

 favorable. 



Here are five rules applying to all rearing work with in- 

 sects : 



1. Maintain natural conditions. 



2. Supply natural food. 



3. Keep out enemies. 



4. Keep close to your stuff. 



5. Be watchful, and anticipate needs.
