Rare
Under 5% of wildlife watchers report an Eastern Saw-Tailed Bush-Cricket sighting in Prague on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 594th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report an Eastern Saw-Tailed Bush-Cricket in Prague on a given day, against under 5% in August to June, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eastern Saw-Tailed Bush-Cricket sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Prague, in our data
Prague is the only city on Wallace's Line with enough records to rate Eastern Saw-Tailed Bush-Cricket sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Eastern Saw-Tailed Bush-Cricket is recorded against all the insects logged in Prague (7 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.
