VIII 

 SUBFAMILY CHCEROCAMPIN^ 



THIS subfamily (the "hog-caterpillars") is named 

 from a fancied resemblance of the caterpillars to 

 pigs. 



Many of the species have the third and fourth seg- 

 ments larger than the others, and some draw the head 

 and first segment into the second, telescope fashion, 

 when at rest and when frightened. 



The moths have large, prominent heads, and fly very 

 swiftly. They are very strong, and have a habit of 

 darting downward when startled ; so the net should 

 always be placed beneath them and swung upward to 

 catch them.
