Polyergus rufescens
In 3 days ~10% in a week ~20%
Polyergus rufescens is a species of slave-making ant native to southern Europe and parts of Asia, commonly referred to as the European Amazon ant or as the slave-making ant. It is an obligatory social parasite, unable to feed itself or look after the colony and reliant on ants of another species to undertake these tasks. To replenish these servant ants, it raids nearby ant colonies and carries home pupae and larvae, and these are reared to provide future workers for the colony. A newly mated female P. rufescens needs to make its way into one of these "host" nests, kill the host queen, and be accepted by the host workers in her place.
P. rufescens workers in western and southwestern Europe are dark red, while eastern specimens are more orange-red. Darker ants often have a purplish or brownish tinge to their gasters and appendages. Morphologically, ants of this species are similar to the Mexican Polyergus topoffi, but have narrower heads and petioles and the first tergites of their gasters are more hairy. The total length of this ant is 4.7 to 7 mm (0.19 to 0.28 in).
P. rufescens is native to parts of Europe including Spain, France, the Netherlands... Wikipedia →

Rare
Under 5% of wildlife watchers report a European Amazon Ant sighting in Prague on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 543rd 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a European Amazon Ant in Prague on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most European Amazon Ant sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 4 cities where we can rate European Amazon Ant sightings, Prague ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%), Bucharest (Romania, under 5%) and Vienna (Austria, under 5%).
Same family: Formicidae
The closest relatives of the European Amazon Ant that you can see in Prague (family Formicidae, Ants) are Jet Ant (about 10%), Central European Bicolored Ant (about 10%) and Dolichoderus quadripunctatus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Amazon Ant is recorded against all the insects logged in Prague (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.
