 Even the caterpillars take advantage of it, and by 

 their minute resemblance to twigs and thorns are 

 enabled to elude their enemies. 



Few entomologists have popularised the attractive 

 study of entomology more than Mr. Edward Newman, 

 whose works on British butterflies and British 

 moths we would recommend our young readers to 

 procure. His distinctions between butterflies and 

 moths we give, as a model of simple and forcible 

 description : " A butterfly always flies in the day- 

 time. In the second place, it always rests by night, 

 and almost always in rainy or cloudy weather. In 

 the third place, when it is resting, it raises its 

 wings, pressing them together back to back ; but a 

 moth turns its wings downwards, folding them 

 round its body. Again, the hind wings of a butter- 

 fly are stiff, and you cannot fold them up ; but the 

 hind wings of a moth are almost invariably neatly 

 folded up lengthwise, and quite hidden beneath the 

 fore wings. Then, again, both butterflies and moths 

 have two feelers attached to the head, just in front 

 of the eyes; we call these antennae. These in 

 different insects are of different shapes ; but in 

 butterflies they generally have a little knob at the 

 end. The owner cannot stow them away or hide 

 them ; whether the butterfly is asleep or awake, its 

 antennas are always stretched out in front, or held 

 quite upright. Now a moth, when going to sleep, 

 turns its antennae under its wing, or conceals them
