Rare
Under 5% of wildlife watchers report a Philhelius dives sighting in Vienna on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 454th 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 30%, if each day is a fresh chance.
June and August
In those months about 10% of wildlife watchers report a Philhelius dives in Vienna on a given day, against under 5% in July and September–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 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Philhelius dives sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Philhelius dives sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Barcelona (Spain, under 5%) and Kyiv (Ukraine, under 5%).
GBIF citizen-science records
It is estimated from how often the Philhelius dives is recorded against all the insects logged in Vienna (32 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.
