"Woolly bear" caterplUar. 



THE ISABELLA TIGER MOTH. 



Prelimhiary zvork.^ During the autumn the pupils are always finding and 

 bringing to school this very noticeable caterpillar. It seems to them a companion 

 of the road and the sunshine, and they themselves have given to it the pet name of 

 " woolly bear." It usually seems in a hurry and a little talk on the part of the 

 teacher telling the pupils that it is trying to find some safe place in which to hide 

 during the season cf cold and snow, will at once interest them in the future of the 

 caterpillar. (See Manual for the Study of Insects, p. 322). If the caterpillar is 

 already curled up for the winter it will "come to'" if warmed in the hand or the 

 sunshine, and will make a good object for this lesson.
