flares out half an inch or more from the tree all around. This 
will prevent the moths getting up, and will need cleaning about 
once a week for jour weeks or more. Probably not one trap

Tent Caterpiilars.—Several species of hairy caterpillars called 
“tent caterpillars,” or “web worms,” from their spinning covers 
of cobweb-like material, under which they take shelter in large 
colonies; but one, at least, of the group does not spin a web, 
though it lives in clusters on the tree. The worms can be killed 
by cutting off and burning the twig holding the cluster or by 
burning the colonies in place with a torch on the end of a pole, 
Larve, Pupze and Moth of Web Worm. 
or by spraying the foliage with Paris green. The pest can be 
reduced by carefully collecting and burning the egg clusters 
while pruning. The egg cluster encircles the twig, as shown in 
the adjacent engraving. 
Red-humped Caterpillar and Moth. 
Red-Humped Caterpillar—Striped caterpillars, not hairy, 
but having two rows of black spines along the back, also living 
in clusters; of reddish color with yellow and white lines; a short 
distance back of the red head of the caterpillar is a red hump on 
which are four black spines; black spines are also scattered over 
the body, but smaller than those on the back. Spray with Paris 
green, or cut off and burn colonies.
