The Aphrodite fritillary (Speyeria aphrodite) is a fritillary butterfly, from North America. This orange coloured fritillary has rows of dark dots or chevrons at the wing edges and black or brown lines more proximally. The ventral sides of the wings are also orange with several rows of white dots. Its wingspan is between 51 and 73 mm.
Aphrodite fritillaries are sensitive to temperature with population trajectories showing declines in response to climate warming trends.

GBIF citizen-science records
It is estimated from how often the Aphrodite Fritillary is recorded against all the insects logged in Riding Mountain National Park (6 verified sightings from 2019 to 2026), 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.
