Rare
Under 5% of wildlife watchers report a Tropical House Cricket sighting in Chennai on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 298th most-seen of the 376 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.
May, August and October

Across all the parks we cover, that three-hour window holds the most Tropical House Cricket sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

Same order: Orthoptera
The closest relatives of the Tropical House Cricket that you can see in Chennai (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Painted Grasshopper (about 20%), Heteracris pulchra (about 20%) and Carinate Locust (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tropical House Cricket is recorded against all the insects logged in Chennai (6 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.
