Emperor," the first "hickory-horned devil," and a full grown Modesta. I con- 

 ducted thorough searches after the following manner. I would select a tree 

 along a creek bed or the road where I could search for ordure. When I espied 

 a pellet and determined that it was fresh I took a stand just over the spot where 

 I found it and looked straight up. Several fresh pellets close together rarely 

 failed to yield a "worm." Shade trees in town along the sidewalks are fine 

 for hunting as the pellets collect on the walk. The half eaten leaves and the 

 bare leaf stalks furnish other evidences of the presence of caterpillars. The full 

 grown larvae of the larger moths are usually to be found clinging, back down, 

 to the mid-rib, leaf stalk or twig near where they have been eating, for cater- 

 pillars almost always eat at night. 



If you are sure a large caterpillar is in a tree and can not sight him, climb 

 up and use a stout club on the limbs. The jar will usually dislodge him and 

 even chances the fall will not kill him. In fact, you do not lose many, if the 

 fall is not too great. Sometimes even when the pellets are comparatively fresh 

 there is no caterpillar on the tree. Doubtless he descended during the night 

 or at early morning and is wandering beneath, in search of a suitable place to 

 spin or burrow, or perhaps he has gathered leaves together near where you found 

 the half eaten foliage, and is spinning a cocoon up there.
