Rare
Under 5% of wildlife watchers report a Zarucco Duskywing sighting in Miami on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 597th 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 a Zarucco Duskywing in Miami on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Zarucco Duskywing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Zarucco Duskywing sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Zarucco Duskywing is recorded against all the insects logged in Miami (8 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.
