Rare
Under 5% of wildlife watchers report a Broad Spark sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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.
June and July
In those months about 10% of wildlife watchers report a Broad Spark in Hong Kong on a given day, against under 5% in August to May, the lowest months. Those are among Hong Kong's wettest months, with about 230 mm of rain a month against 25 mm in December.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Broad Spark sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Broad Spark that you can see in Hong Kong (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Plains Cupid (about 20%) and Abisara echeria (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Broad Spark is recorded against all the insects logged in Hong Kong (11 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.
