In 3 days ~10% in a week ~20%
Tenodera aridifolia, the Japanese giant mantis, is a species of mantis in the subfamily Tenoderinae. The Chinese mantis, T. sinensis, was once considered to be a subspecies of T. aridifolia, but the species can be distinguished by the shape of male genitalia.
Adults are large and slender, with long raptorial forelegs and triangular head. Females are typically between 80-105 mm, and males are typically smaller at 65-85mm. Colour can vary depending on the habitat, from light green to brown. A distinctive feature is a yellowish spot on the base of the fore-coxa, and the hind wings are dark brown to purplish when opened which is key trait for determining the difference between Tenodera aridifolia and T. sinensis.
They are widely distributed across tropical and subtropical East Asia. They are found in southern China, Taiwan, and Southeast Asia.. Despite its name, the species is absent from the temperate regions with harsher winters like northern China, Korea, and mainland Japan, where Tenodera sinensis replaces it.
The Japanese giant mantis thrives in warm, open habitats with abundant prey. Places such as gardens, cultivated fields, forest... Wikipedia →

Rare
Under 5% of wildlife watchers report a Tenodera aridifolia sighting in Hong Kong on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 583rd most-seen of the 1125 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.
July and August
In those months about 10% of wildlife watchers report a Tenodera aridifolia in Hong Kong on a given day, against under 5% in September to June, the lowest months. Those are among Hong Kong's wettest months, with about 200 mm of rain a month against 25 mm in December.
6th of 6
Of the 6 cities where we can rate Tenodera aridifolia sightings, Hong Kong ranks 6th at under 5%. The best odds are in Kunming (China, about 10%), Tuen Mun (China, about 10%) and Taichung (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Tenodera aridifolia is recorded against all the insects logged in Hong Kong (14 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.
