With luck
About 10% of wildlife watchers report a Grain Support Beetle sighting in Vienna on a given day, based on 128 verified sightings from GBIF citizen-science data. It is the 142nd most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Grain Support Beetle in Vienna on a given day, against under 5% in January–February, May and September–October, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Grain Support Beetle sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 6 cities where we can rate Grain Support Beetle sightings, Vienna ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Budapest (Hungary, about 10%), Lyon (France, about 10%) and Bucharest (Romania, about 10%).
Same family: Cerambycidae
The closest relatives of the Grain Support Beetle that you can see in Vienna (family Cerambycidae, Longhorn Beetles) are Alpine Longhorn Rosalia (about 10%), Common Grammoptera (about 10%) and Dorcadion aethiops (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grain Support Beetle is recorded against all the insects logged in Vienna (128 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.
