SOME SUGGESTIONS FOR THE STUDY OF -INSECTS. 163 



Hence the term " frivolous butterfly." No doubt it is 

 daintily put : 



* ; pretty painted butterfly, what do you do all day ? 

 I roam about the sunny fields and nothing do but play. 

 Nothing do but play ! 0, silly painted butterfly to waste 

 your time away." 



But this is not quite fair to the butterfly, as we shall see. 



In the course of examination of the moth, pupils will be 

 able to identify the regions noted in the caterpillar head, 

 thorax, and hind body. It will be most profitable if in 

 this study we make a comparison between the larva and 

 the adult in detail. 



We note on the head in the winged insect 



(1) Longer and finer antennae. They should be 



examined at close quarters. 



(2) Quite new eyes, large and compound in character. 



(3) The mouth parts are transformed. The biting 



jaws of the caterpillar have become long suck- 

 ing jaws in the adult. These jaws will be seen 

 on the under side of the head coiled up like a 

 watch spring (Figs. 62, 63). The moth has 

 complete control over this slender coiled tube, 

 straightening it at will and inserting it into 

 flowers when feeding. 



On the thorax we observe 



(1) The legs are longer and adapted for supporting 



the insect whilst it rests or is feeding or is 

 depositing its eggs upon the food plant. 



(2) The adult insect has two pairs of wings ; the 



caterpillar has none. 



On the abdomen we note 



The stump legs have disappeared. 



Lastly the whole body is smaller and lighter and the 

 arrangement of colour is different.
