SCHOOL COURSES. 31 



II. ANIMAL LIFE : 



In connection with flower studies there should be given 

 a series of lessons upon four common types of insects 

 visiting flowers : beetles, flies, bees and wasps, butterflies 

 and moths. Eecognisable distinguishing marks should 

 be noted and the relations to the flowers visited made 

 clear. Note should be made specially of those insects with 

 short jaws (beetles and flies mostly), with jaws of medium 

 length (bees and wasps), with long jaws (butterflies and 

 moths). What the insects get in each case, and how they 

 serve the flower. 



Study of the main activities in a bee-hive. Life history 

 of humble-bees. 



Rearing of insects in school observational work on their 

 habits and life histories. The following types make pro- 

 fitable subjects of study, viz. : 



Butterflies and Moths various species. 



Beetles procure " Meal-worms " (larvae of Tene- 



brio molitor) from bird dealers and rear in 



bran. 

 Crane Flies rear larvae in soil, feed with grass 



roots, or sow corn and allow them to feed on 



the roots. This can be done in a box. 



General facts learned from the study of insect life : 



Complex inter-relations seen in structural adapta- 

 tions between flowers and insects; between 

 the members of a bee colony, illustrating the 

 principle of division of labour. The same 

 principle illustrated differently in insect life- 

 histories the larval period for feeding and 

 growth, i.e. the individual interest ; the adult 

 period, usually short, for race interest, i.e. the 

 continuation of the species.
