sfcrt'tiiit^j theinsflves tluTcin and fecnl on tlu; foliage. I hc-y are slender, 

 pale green or yellowish green caterpillars sometimes reddish or brownish, 

 about 3/^ inch long, with the head and thoracic shield brown and often a 

 green stripe along the hack. They attain their growth in earl)- June, 

 transform to pupae, delicate brown moths with a wing spread of about fg 

 inch appearing the latter part of June or early in Jul)'. 



Rose leaf folder 



^■\ fillips rosana Linn. 



A dark olive-green, brown-headed caterpillar feeds within the webbed-together leaves 

 of rose and a number of other ])lants. 



This leaf roller is an introduced species and like its allies, iKjt verj' ]jar- 

 ticular as to its food [jlants. It has been recordetl from wild n)s<_', ai)ple, 

 hawthorn, raspberry, hazel, currant and gooseberry. Both larva and moth 

 are darker than those of most of our native species. The brownish gray 

 moth, having a wing spread of about 3_J^ inch appears in early (ime. 



Platynota flavedana Clem. This is another small rose leaf roller liable 

 to cause more or less injury outdoors and likely to invade greenhouses, in 

 which latter it may acquire the bud-eating habit. 



Walnut curculio 



Conotraclu'liis jiiglaiidis Lee. 



A curculio very mu( li resembling the |)luni ))est though 

 larger, '^ inch long, frequently infests walnuts and 

 butternuts. 



This species very closely resembles the plum 

 curculio. It is about y^ inch in length, reddish 

 brown and prettily ornamented with golden and 

 silvery hairs. The most conspicuous feature is 

 the broad transverse whitish band on the posterior 

 third of the wing covers. The curious projec- 

 tions on the wing covers seen in the plum curculio 

 also occur, and an examination with the lens shows them to be strongly 

 ridged and ornamented with several minor processes.
