Rare
Under 5% of wildlife watchers report a Tamil Grass Dart sighting in Mumbai on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 258th most-seen of the 362 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Tamil Grass Dart in Mumbai on a given day, against under 5% in October to August, the lowest months. That is one of Mumbai's wettest months, with about 380 mm of rain against almost none in January.
Only Mumbai, in our data
Mumbai is the only city on Wallace's Line with enough records to rate Tamil Grass Dart sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Tamil Grass Dart that you can see in Mumbai (family Hesperiidae, Skippers) are Indian Palm Bob (about 30%), Grass Demon (about 20%) and Common Awl (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tamil Grass Dart is recorded against all the insects logged in Mumbai (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.
