^ oval beetles, the common little Lady Bird 

 beetles of our nursery days and rhymes. 

 Never kill these ! They are most useful 

 beggars, as are their grubs, grey, active, 

 elongate, six-legged little objects, for 

 they feed upon the plant lice and are 

 there for this purpose alone. 



A common red one with 7 black spots 

 on either side of its back (shown here 

 natural size and enlarged) is spread all 

 over the world and is a friend of almost 

 incalculable value to man. It is the 

 commonest one of our homeland and 

 the friend of our nursery days. Others 

 there are, red and orange and pale 

 yellow with varying black marks on their 

 wing cases. They are all friends and 

 should be treated as such.
