Possible
About 20% of wildlife watchers report a Malaysian Moon Moth sighting in Guwahati on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 77 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Malaysian Moon Moth in Guwahati on a given day, against under 5% in March to January, the lowest months. That is one of Guwahati's driest months, with about 20 mm of rain against 370 mm in June.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Malaysian Moon Moth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Guwahati, in our data
Guwahati is the only city on Wallace's Line with enough records to rate Malaysian Moon Moth sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Malaysian Moon Moth that you can see in Guwahati (order Lepidoptera, Butterflies and Moths) are Red Pierrot (about 50%), Common Evening Brown (about 40%) and Common Mormon Swallowtail (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Malaysian Moon Moth is recorded against all the insects logged in Guwahati (6 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.
