Rare
Under 5% of wildlife watchers report a Northern Triorla sighting in Houston on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 354th 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.
June and July
In those months about 10% of wildlife watchers report a Northern Triorla in Houston on a given day, against under 5% in August to May, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Northern Triorla sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Northern Triorla sightings, Houston ranks 3rd at under 5%. The best odds are in Miami (United States, about 10%) and Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Northern Triorla is recorded against all the insects logged in Houston (33 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.
