This little chamber forms the cocoon, which the insect lineswith a thin, closely-woven layer of silk. The period of pupation lasts for ten days. The moths begin toappear early in June in the Northern States, where the pest is singlebrooded. Prof. Comstocks notes, taken while he was United States Entomolo-gist (1879), show that the larvae pupated in the vicinity of Washington,D. C, as early as May 19th, and the moths began emerging May is, therefore, possible that in the latitude of Washington and in theSouthern States there are two broods each season. This insect has a number of parasitic and other enemies, which aidin holding it in check. It is devoured by many insectivorous birds,and has a formidable foe in the mud-wasp (Odynerus caislilleiisis). Remedies.— It is not practicable to try to check this j)est, says 64 INJURIOUS INSECT
