Likely
About 40% of wildlife watchers report an Alpine Dark Bush-Cricket sighting in Triglav National Park on a given day, based on 75 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 260 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
May, July and September
In those months about 40% of wildlife watchers report an Alpine Dark Bush-Cricket in Triglav National Park on a given day, against under 5% in February–March and October, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Alpine Dark Bush-Cricket sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Alpine Dark Bush-Cricket is recorded against all the insects logged in Triglav National Park (75 verified sightings from 2019 to 2026), 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.
