Rare
Under 5% of wildlife watchers report a Native Drone Fly sighting in Perth on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 254th most-seen of the 275 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.
October
In that month about 10% of wildlife watchers report a Native Drone Fly in Perth on a given day, against under 5% in November to September, the lowest months. That is one of Perth's driest months, with about 30 mm of rain against 130 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Native Drone Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Native Drone Fly sightings, Perth ranks 4th at under 5%. The best odds are in Melbourne (Australia, about 10%), Brisbane (Australia, about 10%) and Sydney (Australia, about 10%).
Same family: Syrphidae
The closest relatives of the Native Drone Fly that you can see in Perth (family Syrphidae, Hover Flies) are Yellow-Shouldered Stout Hover Fly (about 10%) and Common Halfband (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Native Drone Fly is recorded against all the insects logged in Perth (5 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.
