The great spangled fritillary (Speyeria cybele) is a North American butterfly of the family Nymphalidae. Its wingspan ranges from 62 to 88 mm (2.4 to 3.5 in). It is characterized by its orange colour above with five black dashes near forewing base and several irregular black dashes at the base of the hindwing. In addition, two rows of black crescents run along the edges of the wings. Below, the forewing is yellowish orange with black marks similar to the upperside, with a few silver spots on the tip of the wing. The hindwing is reddish brown with silver spots on the base and middle of the wing. A broad yellow band and silver triangles are the most notable qualities on the wing, next to the brown margin. Females tend to be darker than males and individuals from the western reaches of this species range tend to be brighter orange. Similar species include the Aphrodite fritillary (Speyeria aphrodite), the Atlantis fritillary (Speyeria atlantis) and the northwestern fritillary (Speyeria hesperis). It is distinguished from the Aphrodite and Atlantis fritillaries by a wide light submarginal band on the hindwing and instead of black spots, black dashes form on the margins... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Great Spangled Fritillary is recorded against all the insects logged in Edmonton (141 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
