Trigonidium cicindeloides
In 3 days ~20% in a week ~40%
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 Taichung on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 172nd most-seen of the 197 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Common Trig in Taichung on a given day, against under 5% in January–July and October–November, the lowest months. That is one of Taichung's wettest months, with about 330 mm of rain against 40 mm in December.
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, Taichung ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Prayagraj (India, about 10%) and Porto (Portugal, about 10%).
Same order: Orthoptera
The closest relatives of the Common Trig that you can see in Taichung (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Short-Winged Rice Grasshopper (about 30%), Large Green Grasshopper (about 20%) and Carinate Locust (about 10%), 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 Taichung (5 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.
