With luck
About 10% of wildlife watchers report a Striped Blue Crow sighting in Singapore on a given day, based on 79 verified sightings from GBIF citizen-science data. It is the 276th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January, March–July and September–October
In those months about 10% of wildlife watchers report a Striped Blue Crow in Singapore on a given day, against under 5% in February, August and November–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Striped Blue Crow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Striped Blue Crow is recorded against all the insects logged in Singapore (79 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.
