Rare
Under 5% of wildlife watchers report a Dark Posy sighting in Singapore on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 511th most-seen of the 1045 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 Dark Posy in Singapore on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Dark Posy sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Dark Posy sightings, Singapore ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kuala Lumpur (Malaysia, under 5%).
GBIF citizen-science records
It is estimated from how often the Dark Posy is recorded against all the insects logged in Singapore (28 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.
