NOTES FOR THE YEAR 



The season has been remarkable for the scarcity of the apple 

 tent caterpillar and the same has been true to a large extent of shade 

 tree insects. The elm leaf beetle, presumabh^ on account of the 

 relatively cool spring and summer, caused very little injury. 



The marked scarcity of early leaf feeders observed both this 

 season and last was offset to some extent by the abundance of late 

 leaf feeders which was particularly marked in the case of the red- 

 humped and yellow-necked apple worms noticed below, and to a 

 less extent than last year, in the case of hairy caterpillars, such as 

 those of the hickory tussock moth and its associates. 



A number of the more important or unusual insects attracting 

 attention during the j^ear are briefly noticed below. 



FRUIT INSECTS 

 Yellow-necked and red-humped apple caterpillars. (D a t a n a 



m i n i s t r a Drury and Schizura concinna vSm. and 

 Abb.). The yellow-necked and red-humped caterpillars, specially 

 the former, have been exceptionally abundant and injurious, par- 

 ticularly in the upper Hudson valley. These insects were unusually 

 numerous in 19 17, and appear to have been much more abundant 

 the past season. The first reports of injury were received toward the 

 last of June and related to small, red-humped caterpillars feeding 

 upon young trees in Greene county. Injury continued so that
