Rare
Under 5% of wildlife watchers report a Slaty Skimmer sighting in Orlando on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 175th most-seen of the 294 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.
May, July and September
In those months about 10% of wildlife watchers report a Slaty Skimmer in Orlando on a given day, against under 5% in June, August and October–April, the lowest months. Those are among Orlando's wettest months, with about 150 mm of rain a month against 50 mm in November.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Slaty Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
8th of 11
Of the 11 cities where we can rate Slaty Skimmer sightings, Orlando ranks 8th at under 5%. The best odds are in Washington (United States, about 10%), Austin (United States, about 10%) and Boston (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Slaty Skimmer is recorded against all the insects logged in Orlando (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.
