With luck
About 10% of wildlife watchers report a Blue-Striped Nettle Grub sighting in Mumbai on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 362 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Blue-Striped Nettle Grub in Mumbai on a given day, against under 5% in July–September and December–May, the lowest months. That is one of Mumbai's driest months, with about 15 mm of rain against 830 mm in July.
Among the best
Of the 9 cities where we can rate Blue-Striped Nettle Grub sightings, Mumbai ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
Same order: Lepidoptera
The closest relatives of the Blue-Striped Nettle Grub that you can see in Mumbai (order Lepidoptera, Butterflies and Moths) are Common Mormon Swallowtail (about 40%), Tailed Jay (about 40%) and Lime Swallowtail (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-Striped Nettle Grub is recorded against all the insects logged in Mumbai (18 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.
