Trigonidium cicindeloides
In 3 days ~20% in a week ~30%
Trigonidium cicindeloides is a species of sword-tail cricket widespread in Africa, southern Europe, Asia, and Arabia. During mating season males make a sound created by vibrating the last two joints of their maxillary palpi. This is either to attract females for mating or to drive off other males. Wikipedia →

With luck
About 10% of wildlife watchers report a Common Trig sighting in Chennai on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 237th most-seen of the 376 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and October–January
In those months about 10% of wildlife watchers report a Common Trig in Chennai on a given day, against under 5% in February–April and June–September, the lowest months. Those are among Chennai's wettest months, with about 150 mm of rain a month against 5 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Trig sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 11 cities where we can rate Common Trig sightings, Chennai ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Prayagraj (India, about 10%), Porto (Portugal, about 10%) and Taichung (Taiwan, about 10%).
Same order: Orthoptera
The closest relatives of the Common Trig 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 Common Trig is recorded against all the insects logged in Chennai (9 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.
