Rare
Under 5% of wildlife watchers report a Knapweed Ghost sighting in Munich on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 334th most-seen of the 521 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.
July
In that month about 10% of wildlife watchers report a Knapweed Ghost in Munich on a given day, against under 5% in August to June, the lowest months. That is one of Munich's wettest months, with about 140 mm of rain against 60 mm in February.
Among the best
Of the 3 cities where we can rate Knapweed Ghost sightings, Munich ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Tel Aviv (Israel, under 5%).
Same order: Diptera
The closest relatives of the Knapweed Ghost that you can see in Munich (order Diptera, Flies) are Marmalade Hover Fly (about 10%), Common Drone Fly (about 10%) and Hornet Mimic Hover Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Knapweed Ghost is recorded against all the insects logged in Munich (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.
