Nantucket pine moth 



Jiviiria frits/raiia Sciukl. 

 Infesting the new growth o. P . n u s i n .. ,. s. 1". r 1 g i d a, .and perhaps of other 

 species spinning a delicate web around the terminal l.ud, .and min.ng l.oth the twig and 

 thebaJesof the leaves; one or several small yellowish larvae, wh,. h transform w.th.n 

 grayish cocoons, either in their burrows or fastened to the twigs, and become small 

 copper-colored moths, witit wing expanse of nearly '^ in,:h. 



The work of this species was met with on hanl i-ine at Karn.-r in 1901. 

 ■Uu- insect was not specially ahiinWanl, and th.n,-h infested lips were 

 collected, no adtilts were reared. This species is a very seriotis enemy of 

 hard pines on Nantticket Island. Profc-ssor Sciuldc-r, writin^^ of this 

 species in 18S3, states that th.^ pines set out on Nantucket Island 20 or 

 30 years before were dyin^ in lar^e numbers. He atlds that a -reat many 

 have perished, and that most of the livin;^ trees appear sickly. Miss Mary 

 Treat records this species as most destructive- to hard pines in the vicinity 

 of \-ineland X. I. Professor Comstock also received twi.ijs infested by this 

 insect from Prof. S. H. Ga-e of Ithaca. 1 )r A. D. lb.pk,ns records the 

 work of this species as very common alon- Alle-hany Tront. Mineral co.. 

 \V. \'a. He states that thot.oh the characteristic mines were t.-und, 

 scarcely anv larvae or pujiae were obtained. 



Life history and habits. Thr followin- condensed account of the life 

 history and habits of this insect is that -iv<n by Professor CtMitstock : 



About the middle of May .879. the scrub pines (Pin us i ■Y'.^'' 'n 

 Vinrinia, near WashinK'ton, were found to be i^reatly .njurec h^ small 

 le pidopterous larvae. On ntanv trees there was scarcely a new shoot to be 

 found 'which was not infestt.l at its tip by from one to f"- >-;--';• 

 blackdieaded caterpillars. They were so completely concea ed .1 .le a 

 work that their presence would scarcely be notjced, and the e fee of the r 

 work was hardly visible, until th<- twi.^^ was almost completely destroyed.
