Nebria brevicollis, the short-collared gazelle beetle, belonging to the Carabidae family, is a ground beetle. With nearly 500 species and over 100 subspecies, Nebria is the most diverse genus within the Nebriini tribe of ground beetles. Members of the genus occupy a wide range of habitats. Nebria brevicollis is native to Europe and the Near East but has been introduced to the western United States and Canada. Its rapid expansion in North America is characteristic of an invasive species. Due to the variation in habitat, their diet consists of small arthropods (less than 4 mm in length) including Collembola, Diptera, earthworms, mites, and spiders.
Nebria brevicollis has a dark brown body with reddish-brown tibiae, tarsi, palpi, and antennae. The pronotum features two lateral setae on each side and is densely punctuate across its base. This species is most abundant between October and December, then from January through mid-May. It is of modest size, ranging in length from 10–14 mm. It has two sets of wings, protected by a hard shell that is black or dark brown. Only a few beetles have functional flight muscles. No sexual dimorphism has been observed between males and...

Rare
Under 5% of wildlife watchers report a European Gazelle Beetle sighting in Paris on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 827th most-seen of the 916 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 Gazelle Beetle in Paris on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most European Gazelle Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
12th of 12
Of the 12 cities where we can rate European Gazelle Beetle sightings, Paris ranks 12th at under 5%. The best odds are in Portland (United States, about 10%), Vancouver (Canada, about 10%) and Seattle (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the European Gazelle Beetle is recorded against all the insects logged in Paris (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.
