Rare
Under 5% of wildlife watchers report a Hyacinth Glider sighting in Houston on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 263rd 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 30%, if each day is a fresh chance.
July–August and October
In those months about 10% of wildlife watchers report a Hyacinth Glider in Houston on a given day, against under 5% in September and November–June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Hyacinth Glider sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Hyacinth Glider sightings, Houston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Miami (United States, under 5%).

GBIF citizen-science records
It is estimated from how often the Hyacinth Glider is recorded against all the insects logged in Houston (53 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.
