Rare
Under 5% of wildlife watchers report a Blue-Striped Nettle Grub sighting in Singapore on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 847th 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 Blue-Striped Nettle Grub in Singapore on a given day, so our monthly data shows no clear season.
9th of 9
Of the 9 cities where we can rate Blue-Striped Nettle Grub sightings, Singapore ranks 9th at under 5%. The best odds are in Nagoya (Japan, about 10%), Mumbai (India, about 10%) and Osaka (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue-Striped Nettle Grub is recorded against all the insects logged in Singapore (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.
