Il8 STATE POMOLOGICAL SOCIETY. 



The insects which are at this season most troubling the 

 orchard are the red-humped caterpillars and the yellow-necked 

 caterpillars and tussock moths. 



The insect which perhaps has been sent in more than any 

 other from all parts of the State this year, and mistaken almost 

 constantly for the gipsy moth, is a dark, spiny caterpillar, which 

 has been found commonly upon willows and poplars, and once 

 in a while upon apples but not often, — a darkish caterpillar 

 which grows to be nearly two inches long and has brick red spots 

 along the back, and is covered also with black spines. That 

 caterpillar turns into the yellow-edge butterfly, — the common 

 large brown butterfly with yellow border about the wings. 



This spring the insect which was troubling most in the orchard 

 was perhaps the bud moth, and that winters in clustered leaves, 

 so that when you are in search of the brown-tail moth next 

 spring you will be likely to pick off the leaves that are harboring 

 the bud moth and destroy that too. In fact this campaign

against the brown-tail moth is not only a very great benefit in 

 keeping us on the watch for the brown-tail moth, but also for a 

 great many other injurious insects. In hunting for the leaves 

 that will contain the brown-tail moth you get rid of a great many 

 others. 



Rather than to detain you longer in talking about these 

 insects, I shall be very glad to show you the insects themselves,
