Rare
Under 5% of wildlife watchers report a Blue-Faced Darner sighting in Miami on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 186th 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 30%, if each day is a fresh chance.
March and November–December
In those months about 10% of wildlife watchers report a Blue-Faced Darner in Miami on a given day, against under 5% in January–February and April–October, the lowest months. Those are among Miami's driest months, with about 55 mm of rain a month against 190 mm in June.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blue-Faced Darner sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Blue-Faced Darner sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blue-Faced Darner is recorded against all the insects logged in Miami (58 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.
