Rare
Under 5% of wildlife watchers report a Roland's Sallow sighting in Houston on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 633rd most-seen of the 1057 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.
February
In that month about 10% of wildlife watchers report a Roland's Sallow in Houston on a given day, against under 5% in March to January, the lowest months.
Among the best
Of the 4 cities where we can rate Roland's Sallow sightings, Houston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%), Dallas (United States, under 5%) and Boston (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Roland's Sallow is recorded against all the insects logged in Houston (15 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.
