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
