Rare
Under 5% of wildlife watchers report a Southern Migrant Hawker sighting in Vienna on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 599th most-seen of the 1406 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 Southern Migrant Hawker in Vienna on a given day, against under 5% in August to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Southern Migrant Hawker sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 6
Of the 6 cities where we can rate Southern Migrant Hawker sightings, Vienna ranks 3rd at under 5%. The best odds are in Rostov-on-Don (Russia, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Southern Migrant Hawker is recorded against all the insects logged in Vienna (21 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.
