Common NameSt. Lawrence Tiger SeasonalityPeak activity from mid June to early July. IdentificationOur largest tiger moth. Arctia caja and Pararctia yarrowi are superficially similar, but P. parthenos has greatly reduced white markings on the forewing, and the round hindwing spots of A. caja are absent in parthenos. The extent of the dark areas of the hindwing and light markings on the forewing can vary, and have been named as several 'varieties' (Brower, 1973). D. Macaulay image

Life History This species is semivoltine, overwintering first as a 5th instar and again as an 8th instar larva. Almost all Alberta and B.C. records for this species are from even-numbered years, suggesting it has a biennial phenology. Conservation Common. Diet Info
P. parthenos have been observed on willows (Salix) and trembling aspen (Populus tremuloides). Also reported on alder (Alnus) and paper birch (McGugan, 1958). Successful lab hosts include snowberry (Symphoricarpos),…
