Rare
Under 5% of wildlife watchers report a Trachonitis cristella sighting in Vienna on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1090th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Trachonitis cristella in Vienna on a given day, so our monthly data shows no clear season.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Trachonitis cristella sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Pyralidae
The closest relatives of the Trachonitis cristella that you can see in Vienna (family Pyralidae, Pyralid Snout Moths) are Meal Moth (about 10%), Indian-Meal Moth (about 10%) and Rosy-Striped Knot-Horn (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Trachonitis cristella is recorded against all the insects logged in Vienna (7 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.
