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.

Under 5% of wildlife watchers report an Aphrodite Fritillary sighting in Calgary on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 93rd most-seen of the 256 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report an Aphrodite Fritillary in Calgary on a given day, against under 5% in September to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Aphrodite Fritillary is recorded against all the insects logged in Calgary (27 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.
