Tetramorium bicarinatum
In 3 days ~10% in a week ~20%
Tetramorium bicarinatum, is a species of ant of the family Formicidae in the order Hymenoptera that originated in South East Asia. It is a reddish headed medium-sized ant, with mesosoma and waist contrasting with a dark gaster.
The species can adversely affect native biodiversity. It is also said to be a common tramp species which is usually found inside of houses, in greenhouses and shade houses, or in landscaped areas near houses. The Tetramorium bicarinatum's venom arrangement shows potential for a new pharmacologically active substance, bicarinalin. This antibacterial, antimicrobial, and anti-infective compound could potentially be chemically synthesized to combat antibiotic-resistant pathogens by means of drug therapy.

Rare
Under 5% of wildlife watchers report a Bicolored Pennant Ant sighting in Tokyo on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 872nd most-seen of the 1013 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 Bicolored Pennant Ant in Tokyo on a given day, so our monthly data shows no clear season.
22nd of 23
Of the 23 cities where we can rate Bicolored Pennant Ant sightings, Tokyo ranks 22nd at under 5%. The best odds are in Kochi (India, about 10%), Zhuhai [Macau] (China, about 10%) and Lima (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Bicolored Pennant Ant is recorded against all the insects logged in Tokyo (7 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.
