Rare
Under 5% of wildlife watchers report a Macroglossum corythus sighting in Hong Kong on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 819th most-seen of the 1125 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.
December
In that month about 10% of wildlife watchers report a Macroglossum corythus in Hong Kong on a given day, against under 5% in January to November, the lowest months. That is one of Hong Kong's driest months, with about 25 mm of rain against 280 mm in June.
Yes
Of the 2 cities where we can rate Macroglossum corythus sightings, Hong Kong has the highest daily chance: under 5%. Next come Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Macroglossum corythus is recorded against all the insects logged in Hong Kong (8 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.
