Rare
Under 5% of wildlife watchers report a Striped Hairstreak sighting in Denver on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 292nd 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.
July
In that month about 10% of wildlife watchers report a Striped Hairstreak in Denver on a given day, against under 5% in August to June, the lowest months. That is one of Denver's wettest months, with about 60 mm of rain against 15 mm in January.

Across all the parks we cover, that three-hour window holds the most Striped Hairstreak sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 cities where we can rate Striped Hairstreak sightings, Denver ranks 3rd at under 5%. The best odds are in Edmonton (Canada, about 10%) and Toronto (Canada, under 5%).

GBIF citizen-science records
It is estimated from how often the Striped Hairstreak is recorded against all the insects logged in Denver (9 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.
