Carabus granulatus, common name granulated ground beetle, is a species of beetle. It is found across the Palearctic from Ireland to the Russian Far East and has been introduced to North America. It is widespread in Europe. C. granulatus lives in fields, prairies, taiga and in forests. Also along river margins, in fens, lakeshores, and upland peat. It is occasional in gardens.
It is a small Carabus (length between 14 and 20 mm), winged and characterized by an elongated body which is not very convex and an enlarged thorax. The antennae and the legs are black, the upper part of the animal shiny, predominantly greenish bronze, green or occasionally black. The elytra are subparallel with "chain link" (longitudinal grooves with granules).
Carabus granulatus is one of the very few species of ground beetles that have not completely lost their ability to fly, only the mountain forms are short-winged. Nevertheless, the nocturnal animals generally remain on the ground, where they prey on insects, worms and snails. During the day they hide under tree trunks or stones. From autumn to spring, the animals often spend the winter together in tree stumps. The females... Wikipedia →

With luck
About 10% of wildlife watchers report a Granulated Ground Beetle sighting in Vancouver on a given day, based on 105 verified sightings from GBIF citizen-science data. It is the 72nd most-seen of the 482 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March–May and July–January
In those months about 10% of wildlife watchers report a Granulated Ground Beetle in Vancouver on a given day, against under 5% in February and June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Granulated Ground Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 19 cities where we can rate Granulated Ground Beetle sightings, Vancouver ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Edmonton (Canada, about 10%) and Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Granulated Ground Beetle is recorded against all the insects logged in Vancouver (105 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.
