Myrmica ruginodis
In 3 days ~10% in a week ~20%
Myrmica ruginodis is a species of ant that lives in northern parts of Europe and Asia. It is very similar to M. rubra, but has a more northerly and higher-altitude distribution. Overwintering larvae may become either workers or queen ants, with up to 20 queens living in a colony of up to 2,500 individuals. Two subspecies are recognised, differing in the relative size of the queen.
There is a close resemblance between Myrmica ruginodis and Myrmica rubra, another common species across much of Eurasia. They differ in the shape of the base of the antennae, which are curved in M. ruginodis and sharply angled in M. rubra, and in the spines projecting from the back of the thorax – in M. ruginodis, these are as long as the distance between their tips, while in M. rubra, they are shorter.
Myrmica ruginodis is found across the northern Palaearctic region, at higher altitudes and latitudes than M. rubra. Its range extends from Western Europe to Japan, and from Italy in the south to the Norwegian North Cape in the north. M. ruginodis is the only species of ant to have been recorded from all of the vice-counties into which the British Isles are divided... Wikipedia →

Rare
Under 5% of wildlife watchers report a Woodland Red Ant sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th most-seen of the 1504 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 Woodland Red Ant in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Woodland Red Ant sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Nizhny Novgorod (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Woodland Red Ant is recorded against all the insects logged in London (6 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.
