The Great Spangled Fritillary (Speyeria cybele) is a butterfly of the Nymphalidae family.
Our largest fritillary, usually with a wingspan over 65 mm. Unlike some of the other fritillaries, cybele is relatively easy to distinguish by the contrasty, dark basal half of the dorsal hindwing; the basal dark area is smaller and more diffuse in other Speyeria. Cybele also lacks the black, angled spot nearest the anal margin on the dorsal forewing base. Two well-defined subspecies occur in Alberta, pseudocarpenteri inhabiting the parkland and northern prairies, and leto of the southern foothills and prairies. Leto has brighter orange males with smaller upperside dark markings and striking, straw and charcoal females.
Southern BC and central Alberta east across southern Canada and the central US to the Atlantic seaboard (Scott 1986). A disjunct population in the Peace River region of AB / BC is the northernmost in North America.
Aspen parkland, shrubby prairie coulees, open woods of the fotthills and southern boreal.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Males use pheromones to attract females. Visual cues are also used in mate recognition. Females use chemical cues to find a suitable host plant on which to lay eggs.
Communication Channels: visual ; chemical
Other Communication Modes: pheromones
Perception Channels: visual ; tactile ; chemical
Not of concern.
Degree of Threat: D : Unthreatened throughout its range, communities may be threatened in minor portions of the range or degree of variation falls within natural variation
