silky thread, of use to the animal as it crawls from leaf 

 to leaf, or with many species finally forming a case, the 

 cocoon (ko koon'), in. which the pupal stage is passed. 

 From the cocoon, the adult, or imago (I ma' go), finally 

 emerges, and leads a life quite harmless to vegetation. 



Two groups of Lepidopterous (lep i dop'ter us) Insects 

 have been popularly and scientifically distinguished. 



The Moths are generally nocturnal, have the antennae of 

 variable form, and, while resting, fold their 

 wings into a roof, which covers the body. 

 The common Clothes Moth, or Wliiie,

ers. These soon hatch, and the larvae 

 begin their paths, always, however, keep- 

 ing themselves covered in a case, made from the material 

 on which they feed. Thus covered, they undergo their 

 transformation. 



The Tent Caterpillar Moth 

 deposits her eggs in a band 

 around the twig of some fa- 

 vorite tree. These hatch in 

 April or May, and the young 

 form a silken tent, in which 

 they remain, until forced by 

 hunger to crawl forth in 

 search of food, leaving behind 

 a trailing thread, which they 

 follow back to their habita- 

 tion on relieving their hunger. 

 Few birds molest them. 



The SilJwvorm, a most valuable insect, is regarded 



PIG, 130.
