Trigonidium cicindeloides
In 3 days ~10% 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 →

Rare
Under 5% of wildlife watchers report a Common Trig sighting in Rome on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 247th most-seen of the 289 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.
April, June and August
In those months about 10% of wildlife watchers report a Common Trig in Rome on a given day, against under 5% in May, July and September–March, the lowest months. Those are among Rome's driest months, with about 40 mm of rain a month against 110 mm in November.
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.
6th of 11
Of the 11 cities where we can rate Common Trig sightings, Rome ranks 6th at under 5%. 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 Rome (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Egyptian Bird Grasshopper (about 20%), Lamenting Grasshopper (about 10%) and Southern Field Cricket (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 Rome (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.
