Rare
Under 5% of wildlife watchers report a Tasmanian Eucalyptus Beetle sighting in London on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1219th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Tasmanian Eucalyptus Beetle in London on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Tasmanian Eucalyptus Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Tasmanian Eucalyptus Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Tasmanian Eucalyptus Beetle that you can see in London (family Chrysomelidae, Leaf Beetles) are Rosemary Beetle (about 20%), Alder Leaf Beetle (about 10%) and Hawthorn Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tasmanian Eucalyptus Beetle is recorded against all the insects logged in London (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.
