Rare
Under 5% of wildlife watchers report a Dideopsis aegrota sighting in Sydney on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 621st most-seen of the 742 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 Dideopsis aegrota in Sydney on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Dideopsis aegrota sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 8 cities where we can rate Dideopsis aegrota sightings, Sydney ranks 8th at under 5%, level with the leaders once rounded. The best odds are in Hong Kong (China, under 5%), Tuen Mun (China, under 5%) and Taipei (Taiwan, under 5%).
Same family: Syrphidae
The closest relatives of the Dideopsis aegrota that you can see in Sydney (family Syrphidae, Hover Flies) are Yellow-Shouldered Stout Hover Fly (about 10%) and Native Drone Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dideopsis aegrota is recorded against all the insects logged in Sydney (6 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.
