Rare
Under 5% of wildlife watchers report a Phileurus valgus sighting in Houston on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 847th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Phileurus valgus in Houston on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Phileurus valgus sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 4 cities where we can rate Phileurus valgus sightings, Houston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%), San Antonio (United States, under 5%) and Dallas (United States, under 5%).
Same family: Scarabaeidae

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