296 NATURE-STUDY REVIEW [15:7—00^,1919 



SO on, the ranks continually widening behind, like a flock of wild 



geese on the wing, but in 



perfectly regular order. 



When about half grown 



they disperse and each one 



shirks for himself." 



. , -I We were rearing a brood 



Automens to, larva 



of the lo caterpillars one 

 summer in a pasteboard box ; one day the cover of netting became 

 loosened and the caterpillars started to escape; they reached 

 the edge of the box and evidently considered it the high road to 

 freedom, for they began to march around and around on it in 

 Indian file; some were larger than the others, so the procession 

 had an uneven appearance, but it was determined and consistent 

 in morale and evidently thought it was getting somewhere. If we 

 had not rescued the little green pin-cushions and given them fresh 

 forage, they would have marched on until exhausted. The 

 caterpillars feed upon apple, cherry, willow, elm, currant and 

 many other plants. 



The Regal Moth 



This is the beautiful moth which has attained such a wide 

 reputation through the charming story "The Girl of the Limber- 

 lost." Mrs. Porter certainly did justice to this glorious creature 

 but it is not so rare now as it was in the day of "The Girl," for 

 collectors sell specimens of it for twenty-five cents apiece. Its 

 front wings are greenish-gray with all the wing-veins outlined 

 broadly with orange-red and are adorned with patches of yellow; 

 the hind wings are orange-red with yellow patches; the wings, 

 when expanded measure five or six inches across. 



The Regal moth has a perfectly adequate and magnificent cater- 

 pillar, which people uneducated to caterpillar standards call "The 

 Hickory Horned Devil;" for it is hard to imagine such a formid- 

 able looking creature to be so perfectly hannless, as it is. When it 

 is fully grown it measures four or five inches in length ; it is green 

 with a "bias" band of pale blue sometimes white on each side of 

 each segment; the head and legs are orange colored; each seg- 

 ment of the body is adorned with red spines but the upper pair 

 on the second and third segments back of the head are what 

 gives the popular name for they are long and look like red horns.
