Rare
Under 5% of wildlife watchers report a Waved-Lined Geometrid sighting in Brisbane on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 856th most-seen of the 1083 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 Waved-Lined Geometrid in Brisbane on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Waved-Lined Geometrid 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.
Among the best
Of the 2 cities where we can rate Waved-Lined Geometrid sightings, Brisbane ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Melbourne (Australia, under 5%).
Same family: Geometridae
The closest relatives of the Waved-Lined Geometrid that you can see in Brisbane (family Geometridae, Geometer Moths) are Apple Looper (about 10%), Comostola laesaria (about 10%) and Cleora repetita (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Waved-Lined Geometrid is recorded against all the insects logged in Brisbane (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.
