Extract

A considerable amount of literature has been published on the genus Pseudohazis and its species but there is only one brief mention of the possibility of a two-year life cycle (Dyar 1904). Several rearings of P. eglanterina form normalis Dyar, completed by the author, have provided conclusive evidence that a two-year cycle is the usual life history pattern in southwestern British Columbia. One such rearing is herein described. This two-year cycle, the first winter in the egg stage and the second winter in the pupal stage, is not in phase as mature larvae and adult moths may be found in the same area at the same time. Detailed descriptions of larval and adult stages are in Dyar 1894 and Packard 1912. Acknowledgment is due to Dr. E. G. Munroe, Unit of Systematic Entomology, Ottawa, for his assistance in reviewing literature and specimen material
