Rare
Under 5% of wildlife watchers report a Myllocerus discolor sighting in Bengaluru on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 288th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January and July–August
In those months about 10% of wildlife watchers report a Myllocerus discolor in Bengaluru on a given day, against under 5% in February–June and September–December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Myllocerus discolor sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Bengaluru, in our data
Bengaluru is the only city on Wallace's Line with enough records to rate Myllocerus discolor sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Myllocerus discolor is recorded against all the insects logged in Bengaluru (10 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.
