Possible
About 20% of wildlife watchers report an Australian Tortoise Beetle sighting in Channel Islands National Park on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 131 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.
July
In that month about 30% of wildlife watchers report an Australian Tortoise Beetle in Channel Islands National Park on a given day, against under 5% in February, October and December, the lowest months. That is one of Channel Islands National Park's driest months, with almost no rain against 60 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Australian Tortoise Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Channel Islands National Park, in our data
Channel Islands National Park is the only park on Wallace's Line with enough records to rate Australian Tortoise Beetle sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Australian Tortoise Beetle is recorded against all the insects logged in Channel Islands National Park (44 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.
