In 3 days ~20% in a week ~50%
Titanodula formosana, also known as the Formosan giant mantis, is a species of praying mantis in the subfamily Hierodulinae. T. formosana is found in China, Taiwan, Malaysia and the Sunda islands. T. formosana was originally placed in Hierodula, but a 2020 study moved the species to a new genus, Titanodula, based on its large size and the unique shape of the male genitalia. Wikipedia →

With luck
About 10% of wildlife watchers report a Formosan Giant Mantis sighting in Hong Kong on a given day, based on 78 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Formosan Giant Mantis in Hong Kong on a given day, against under 5% in April and May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Formosan Giant Mantis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Formosan Giant Mantis sightings, Hong Kong ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Taipei (Taiwan, about 10%), Fuzhou (China, about 10%) and Changsha (China, about 10%).
Same family: Mantidae
The closest relatives of the Formosan Giant Mantis that you can see in Hong Kong (family Mantidae, Mantids) are Giant Asian Mantis (about 20%) and Asian Jumping Mantis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Formosan Giant Mantis is recorded against all the insects logged in Hong Kong (78 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.
