Possible
About 30% of wildlife watchers report an Arboreal Bicolored Slender Ant sighting in Sundarbans National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 15 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report an Arboreal Bicolored Slender Ant in Sundarbans National Park on a given day, against under 5% in January and July, the lowest months. That is one of Sundarbans National Park's driest months, with about 55 mm of rain against 480 mm in July. June has too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Arboreal Bicolored Slender Ant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Arboreal Bicolored Slender Ant sightings, Sundarbans National Park has the highest daily chance: about 30%. Next come Nagarhole National Park (India, about 20%) and Chitwan National Park (Nepal, about 20%).
GBIF citizen-science records
It is estimated from how often the Arboreal Bicolored Slender Ant is recorded against all the insects logged in Sundarbans National Park (5 verified sightings from 2019 to 2026), 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.
