General DescriptionA moderate-sized, predominantly black cicada with yellowish-tan markings. The combination of both narrow forewings (width:length 0.29 - 0.31) and primarily boreal distribution will segregate the Canadian Cicada from all others except Say's (O. rimosa), which is superficially very similar; to reliably separate specimens of canadensis from rimosa the structure of the tymbal must be examined, which has 10 to 11 ribs in canadensis and 7 to 8 (rarely 9) ribs in rimosa (Alexander et al. 1972). In Michigan, rimosa is marked with a brighter orange compared to the tan markings of canadensis (Alexander et al. 1972), but it is not clear if this trait holds up for Alberta populations since museum amterial is limited. There are likely habitat and song differences as well, but this data is also lacking for Alberta populations.
