With luck
About 10% of wildlife watchers report a Dendrobium Beetle sighting in Blue Mountains National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 359th most-seen of the 789 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
September and December–April
In those months about 10% of wildlife watchers report a Dendrobium Beetle in Blue Mountains National Park on a given day, against under 5% in May–August and October–November, the lowest months.

Across all the parks we cover, that three-hour window holds the most Dendrobium Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Blue Mountains National Park, in our data

GBIF citizen-science records
It is estimated from how often the Dendrobium Beetle is recorded against all the insects logged in Blue Mountains National Park (11 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.
