28-^ THE PSYCHOLOGY 



Comp.-uv (ho i.-liry,s;ilis with the larva, ami toll how they resemble each other. 

 Make a drawing of" the chrysalis. Compare different chrysalids. 



How many parts in the butterfly? How many wing-s and legs? Where are 

 lhe\- attached? Make a drawing of the whole and of the parts. Compare with 

 larva and with chrysalis. 



Hi:ad and Sknse Organs: Examine the eyes with a lens and describe. 



Examine the antenna?. Compare with other butterflies and moths. Draw. 



Examine the tongue and compare with the mouth parts of the lar\'a. 



Can it hear? Experiment to discover. 



Can it smell ? Experiment to discover. 



Eggs: Observe a butterfly deposit its eggs. Where are they deposited? 

 Why? How many are deposited in a place? Keep in a box until they hatch. 

 How long before they hatch ? Observe development of the larva and compare 

 different stages with each other, and with other larvre. Make drawings of each 

 stage to keep for reference. 



THIRD STAGE, (12 to J6 Years of Age.) 



The aim of the third stage should be to discover relations. Whereas we have 

 been more concerned about the where, how and the what, we now become 

 concerned with the why. Finally, we classify the specimen as minutely as possible. 



Material: As before and in addition v;M-bal descriptions of different forms of 

 animal life and an analytical key of each branch, partly, at least, the pupil's own 

 work. 



Home: In addition to what has been learned before the student should now 

 determine what effect the larva has on its food plant. Does it destroy it entirely 

 or in part ? How does the butterfly benefit the flowers? Why has the butterfly 

 so long a tongue? What relation is there between the length of its tongue and 

 the flowers it visits? What relation exists between the time ot appearance of 

 certain butterflies and of certain flowers ? 



Movements: Why does it moult its skin ? Why does it become restless 

 before moulting? Of what benefit is this restlessness to the larva ? Has it any 

 movements which are protective? Read about the migration of butterflies, and 

 what they do in winter. Compare with other insects, and with birds. 



Food: Why are not certain butterflies found in Canada? 



What determines their range? 



Which is most easily killed by poisoning, the larva; or the butterfly? Why? 



If you find larva; on different plants, find from your botany if there is any 

 relationship between these plants. They will probably belong to the same family. 



Color: Observe if the different forms are protected by their color? 



Compare the color of the larvae in different conditions. 



Compare the color of the chrysalis with the surface on which it rests. 



Structl'RE; Compare all the butterflies studied with one another, and with 

 other insects, spiders, etc. 



Tell what is characteristic of all butterflies which distinguishes them from 

 moths, beetles, etc. Group the different species studied according to their 

 resemblances. How are they adapted to their mode of living? 



Life History : Write a complete account of its life.
