Rare
Under 5% of wildlife watchers report a Ravanoa xiphialis sighting in Kochi on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 428 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.
August and December
In those months about 10% of wildlife watchers report a Ravanoa xiphialis in Kochi on a given day, against under 5% in January–July and September–November, the lowest months.
Only Kochi, in our data
Kochi is the only city on Wallace's Line with enough records to rate Ravanoa xiphialis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Ravanoa xiphialis that you can see in Kochi (family Crambidae, Crambid Snout Moths) are Hawaiian Beet Webworm Moth (about 20%), Hydrilla Leafcutter Moth (about 10%) and Rice Case Bearer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ravanoa xiphialis is recorded against all the insects logged in Kochi (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.
