Rare
Under 5% of wildlife watchers report a Green Silver-Lines sighting in Prague on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 647th most-seen of the 724 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 Green Silver-Lines in Prague on a given day, against under 5% in August to June, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Green Silver-Lines sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
10th of 10
Of the 10 cities where we can rate Green Silver-Lines sightings, Prague ranks 10th at under 5%. The best odds are in Porto (Portugal, about 20%), Kharkiv (Ukraine, about 10%) and Essen (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Silver-Lines is recorded against all the insects logged in Prague (5 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.
