and so suitable for her purpose. Then she stands almost up- 

 right on her long hind-legs, and begins to bore a hole with the 

 sharp spike at the end of her tail, turning her body from side 



to side just as a carpenter turns 

 a brad-awl. When she has made 

 a deep enough hole, she places an 

 egg in it, moves on a little way, 

 and bores another hole. And so 

 she goes on until all her eggs are 

 laid. 



A daddy-long-legs apparently 

 has only two wings. But, if we 

 look closely, we shall see a pair 

 of small knobs at the end of little 

 footstalks, just where the hind- 

 wings ought to be. These are 

 really the hind-wings. They are 

 called " balancers ", and the odd 

 thing is that, although they are so 

 small, the daddy-long-legs cannot 

 fly without them. Even if only 

 one of them is damaged it cannot 

 rise from the ground, but flutters about just as though the wings 

 themselves were injured. Blue-bottles, house-flies, gnats, and many 

 other insects have these balancers instead of hind-wings.

LEPIDOPTERA 



This beautiful group of insects, as the name of the order 

 (Lepidoptera) implies, have their wings covered with minute scales, 

 to the presence of which they owe their wonderful colouring and 

 often gorgeous appearance. 



Butterflies and Moths are so much alike in general build, and 

 in their life-histories, that it is difficult to draw an exact line
