Rare
Under 5% of wildlife watchers report a Blackjack Fly sighting in Hong Kong on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 868th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Blackjack Fly in Hong Kong on a given day, so our monthly data shows no clear season.
Among the best
Of the 5 cities where we can rate Blackjack Fly sightings, Hong Kong ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Auckland (New Zealand, under 5%).
Same order: Diptera
The closest relatives of the Blackjack Fly that you can see in Hong Kong (order Diptera, Flies) are Ptecticus aurifer (about 10%), Yellow-Shouldered Hover Fly (about 10%) and Microstylum dux (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blackjack Fly is recorded against all the insects logged in Hong Kong (7 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.
