Possible
About 20% of wildlife watchers report a Common Sluggish Katydid sighting in Rottnest Island on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 7 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Common Sluggish Katydid in Rottnest Island on a given day, against under 5% in February–June and November, the lowest months. That is one of Rottnest Island's wettest months, with about 110 mm of rain against 5 mm in December.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Common Sluggish Katydid sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Rottnest Island, in our data
Rottnest Island is the only park on Wallace's Line with enough records to rate Common Sluggish Katydid sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Common Sluggish Katydid is recorded against all the insects logged in Rottnest Island (7 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.
