Possible
About 20% of wildlife watchers report a Tessellated Stick Insect sighting in Brisbane on a given day, based on 477 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December to February
In those months about 30% of wildlife watchers report a Tessellated Stick Insect in Brisbane on a given day, against under 5% in June and July, the lowest months. Those are among Brisbane's wettest months, with about 140 mm of rain a month against 40 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Tessellated Stick Insect sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Tessellated Stick Insect sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Phasmatidae
The closest relatives of the Tessellated Stick Insect that you can see in Brisbane (family Phasmatidae) are Titan Stick Insect (about 10%), Children’s Stick Insect (about 10%) and Spur Legged Phasmid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tessellated Stick Insect is recorded against all the insects logged in Brisbane (477 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.
