ORCHARD INSECTS

with two nearly parallel white bands extending obliquely 

 across the fore wings. The wings of the females expand 

 about H inches, while the males are smaller and may be dis- 

 tinguished by their feathery antennae. The egg-mass is 

 from one-half to three-fourths inch long, and contains about 

 200 eggs, placed 

 together on end. It 

 is covered with a 

 glue which gives a 

 tough glistening 

 surface to the whole 

 mass, and forms a 

 knot-like band 

 around the twig. 



The egg-masses 

 may be easily found 

 and pruned off 

 during the winter. 

 It is well to leave 

 them in the orchard 

 in a box covered 

 with netting so that 

 the parasites may 

 escape. Neglected 

 apple and cherry 

 trees should be de- 

 stroyed, as they merely harbor this and other pests. Spray- 

 ing with arsenate of lead just as the foliage comes out 

 will readily destroy the caterpillars.

 one often finds a mass of caterpillars, huddled together as 

 if confessedly guilty, on the defoliated tip of an apple
