Speyeria callippe, the callippe fritillary, is a North American species of butterflies in the brush-footed family Nymphalidae. Speyeria callippe can reach a wingspan of 5–6.4 cm (2.0–2.5 in). In these large and widespread butterflies the color of the upperside of the wings varies from tawny to bright red-brown with black evenly-spaced zigzag stripes. The entire outer contour is black-brown, divided by a row of pale lunules. The underside of the forewings is red fawn, with the same design as above, and a series of marginal silver lunules. The underside of the hindwings is brown, with about twenty-two large silvered spots and triangular silver submarginal spots with narrow brown edges. In the last stage the larvae are greyish, with black and grey patches and black-orange spines.

With luck
About 10% of wildlife watchers report a Callippe Fritillary sighting in Grand Teton National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 140 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Callippe Fritillary in Grand Teton National Park on a given day, against under 5% in October to May, the lowest months. That is one of Grand Teton National Park's driest months, with about 20 mm of rain against 85 mm in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Callippe Fritillary sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Callippe Fritillary is recorded against all the insects logged in Grand Teton National Park (21 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.
