PART I.—INSECTS 
INTRODUCTORY NOTES 
An insect must have: (1) Head, chest and 
abdomen; (2) antennae (feelers) ; (3) six legs— 
no more, no less. Hence spiders, centipedes, and 
many other crawling creatures should not be called 
insects. 
The usual insect cycle is egg, larva, pupa, insect. 
(Plural number of larva and pupa are larvae, 
pupae.) There are three kinds of larvae, viz., 
caterpillar, grub and maggot. 
CATERPILLAR has three pairs of feet and from 
two to five pairs of fleshy “crawlers." 
GRUB has three pairs of feet, but no "crawlers." 
MAGGOT has neither feet nor “crawlers” (e.g., 
maggots of blowfly and honey-bee). 
PUP2E of many different insects can be found 
amongst dead leaves and weeds, or when digging 
in the garden, especially in the months of March 
and April. If these are placed in glass jam-jars 
or jelly-jars, each having a shallow layer of soil 
on the bottom and a perforated lid, the scholars 
will in time get evidence of the different kinds of 
insects which have this previous stage of existence. 
By means of a glass-fronted box in which half-a-
