Rare
Under 5% of wildlife watchers report a Guenee's Emerald sighting in Melbourne on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 441st most-seen of the 875 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 Guenee's Emerald in Melbourne on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Guenee's Emerald sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Melbourne, in our data
Melbourne is the only city on Wallace's Line with enough records to rate Guenee's Emerald sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Guenee's Emerald that you can see in Melbourne (family Geometridae, Geometer Moths) are Apple Looper (about 20%), Plantain Moth (about 20%) and Red-Lined Looper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guenee's Emerald is recorded against all the insects logged in Melbourne (19 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.
