CLEAR-WING MOTHS OF FAMILY AEGERIIDAE 131 



They seem to elude capture. D. S. KelHcott, author of the species, gives 

 an excellent account of the habits and the difficulties in rearing the insect. 

 Briefly, it is an aggravating and dirty job. In the vicinity of New York 

 City well-established colonies are found in parks, cemeteries, gardens, and 

 lanes in suburban districts. Aside from white pine the insect is partial to 

 Norway spruce, Picea abies, the nodules of resin often being most numer- 

 ous on such trees. A thriving colonization followed the planting of white 

 pine along the shores of the reservoir at Pensico and Croton, N. Y., 20 

 to 25 years ago. The trees now are of a size to be attractive. Hundreds 

 of the resinous masses have been noted here in recent years, many within 

 reach and others beyond. Small and soft, year-old masses and those three 

 years old or older, which are large and hardened, can be disregarded. 

 Immature larvae removed from their burrows invariably perish. Only 

 2-year old masses of firm, but still sticky, consistency hold promise of 

 containing pupae late in June or early in July. The exact location of 

 the pupal chamber is well concealed. Cautious probing is necessary, 

 and losses are unavoidable as the slightest prick or contact with the sticky 

 resin is fatal to the pupa. My method has been to prepare tubes of soft 

 paper to receive the pupae upon uncovering the chambers. Ten healthy 

 pupae from 100 selected masses is a fair average. Parasites of the hymen- 

 opterous family Eulopliidae and a species of larvaevorid fly take a very 

 large toll.
