Rare
Under 5% of wildlife watchers report a Twig Looper sighting in Sydney on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 558th 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 Twig Looper in Sydney on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Twig Looper sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Twig Looper sightings, Sydney ranks 3rd at under 5%. The best odds are in Melbourne (Australia, about 10%) and Hobart (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Twig Looper is recorded against all the insects logged in Sydney (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.
