Fig. 12. Development of Lepidoptera (moths and butterflies) 



The egg, a, hatches into a wormlike larva, or caterpillar, b. The larva feeds vora- 

 ciously and grows very rapidly. On reaching full growth it curls up, secretes a hard 

 covering, and goes to sleep. In this resting stage, or pupa, c, it may remain for 

 months, giving no outward sign of life whatever. At the end of the resting period 

 the cover of the pupa breaks open, and out crawls the fully formed insect, d. In 

 some species the two sexes have distinct forms or color patterns in the adult stage. In 

 the tussock moth the adult female is a sluggish, wingless animal. (All about f size)
