Ermine Moth 



Yponomentidae 



Small moths with snowy white, black 

 dotted front wings. The hind wings are 

 gray or leaden in color. 



Imported to New York from Europe 

 upon nursery stock. 



As the larvae feed upon the foliage 

 they are easily controlled by arsenical 

 sprays. 



They attack apple and cherry as well 

 as a variety of other plants.

European Fruit Scale or Curtis Scale 



Aspidiotus Ostreaeformis 

 The female is circular or broadly oval 

 in outline, dark ashy gray in color with

 nearly white. The exuvia is central or 

 nearly so, dark brown, usually naked and 

 glossy. Diameter % of an inch. 



life History 



The winter is passed by partly grown 

 individuals which become mature early 

 in the summer. The insect gives birth 

 to living young which begin to appear 

 soon after the maturity of the female. In 

 this State they are apparently but one 

 brooded. 



This scale has been recorded from a 

 number of different plants, among them, 

 the apple, pear, plum, peach, cherry, 

 birch, poplar, horse chestnut, basswood, 

 alder, haw, maple, aspen, oak. etc. It 

 has been reported in this country from 

 Maine, New York, New Jersey, Michi- 

 gan. Ohio, Iowa, Idaho, California and 

 several other states. In Maine it is most 

 frequently found on large trees in old 

 and neglected orchards, though we have 

 records also of its occurrence on cur- 

 rant bushes. Specimens the past season

Remedies 



Spraying with lime-sulphur late in the 

 winter or early spring before the ap- 

 pearance of the leaves will control it.

Eye Spotted Bud Moth 



Tmetocera ocellana Schliett

 The larvae of this moth resemble those 

 of the Peach and Prune Twig Miner quite 

 closely, and they are often mistaken one 

 for the other, but the latter work only 

 on the stone fruits, while the former 

 work on practically all of the orchard 

 trees. By careful examination they can 

 readily be distinguished by the anal 

 shield, which on the above insect is shin- 

 ing black like the head and thoracic
