Idaea costaria is a species of moth of the family Geometridae. It is found in south-eastern Australia. Idaea costaria is externally very similar to Idaea inversata but, unlike that species, has a two-coloured head pattern. Idaea costaria has a creamy-white patch between the antennae, whereas I. inversata is dark reddish throughout this area. Wikipedia →

Rare
Under 5% of wildlife watchers report an Idaea costaria sighting in Melbourne on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 808th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Idaea costaria 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 Idaea costaria sightings with a recorded time, and nearly all 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 Idaea costaria sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Idaea costaria is recorded against all the insects logged in Melbourne (5 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.
