Rare
Under 5% of wildlife watchers report an Oak Hairstreak sighting in Miami on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 424th most-seen of the 826 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Oak Hairstreak in Miami on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Oak Hairstreak sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Oak Hairstreak sightings, Miami ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%).
Same family: Lycaenidae
The closest relatives of the Oak Hairstreak that you can see in Miami (family Lycaenidae, Gossamer-winged Butterflies) are Atala (about 30%), Ceraunus Blue (about 10%) and Cassius Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oak Hairstreak is recorded against all the insects logged in Miami (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.
