Rare
Under 5% of wildlife watchers report a Tryon's Hawkmoth sighting in Sydney on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 520th most-seen of the 742 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 Tryon's Hawkmoth in Sydney on a given day, so our monthly data shows no clear season.
2nd of 2
Of the 2 cities where we can rate Tryon's Hawkmoth sightings, Sydney ranks 2nd at under 5%. The best odds are in Brisbane (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Tryon's Hawkmoth is recorded against all the insects logged in Sydney (8 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.
