Cicindela formosa
In 3 days ~10% in a week ~20%
Cicindela formosa, the big sand tiger beetle, is a species of flashy tiger beetle in the family Cicindelidae. It is found in North America. Cicindela formosa overtime has had the ability to change the color patterns on its body which was found through genetic lineages. Although some say its traits come from genomic evolution, the change in its appearance mostly comes from environmental pressures such as predation and the transfer of heat, which shows that it is an effect of the interaction of the environment rather than traits from shared ancestry.

Rare
Under 5% of wildlife watchers report a Big Sand Tiger Beetle sighting in Denver on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 206th most-seen of the 461 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and June
In those months about 10% of wildlife watchers report a Big Sand Tiger Beetle in Denver on a given day, against under 5% in May and July–March, the lowest months.
Only Denver, in our data

GBIF citizen-science records
It is estimated from how often the Big Sand Tiger Beetle is recorded against all the insects logged in Denver (17 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.
